Title: Teds new project a CB500 K1 mostly version 0.5 circa 1972.
Post by: McCabe-Thiele (Ted) on September 10, 2022, 10:22:03 PM
Firstly thanks to Bryan(j) for parting with his long owned yet unrestored  500 plus a huge thank you to (Laverda)Roo for his part in delivering the bike to me here In Derby today.
On the plus side it runs.  I'm sure Bryan would agree it needs some restoration / tlc.
I know there are several ongoing 500/550 builds but I feel the need to add my journey to the list. I will post a before photo shortly.

I could not wait until morning so tonight I fired her up - she sounded so much better than my 400 did on first time start up - somehow I could feel the extra power when I blipped the throttle.
So many decisions to make - I'm minded to sort out some insurance cover & ride it to decide if the engine need to be taken apart as part of the restoration.
Lots of pimply chrome etc as you would expect for a 50 year old bike - I love the rear grab rail arrangement.
Lots of work to do - lots of time to spend sorting her out - I'm going to be a little more sensible about costs on this build but those signature gold alloy rims are already pecking at me to be fitted.lol

It's a good start.

I have noticed though that it looks like the D washer is missing from the N/S top yoke pinch bolt, they might both be missing. You need these in to stop the top yoke breaking when the bolt is tightened.

Looks to be a US K1, the left hand switchgear isn't correct for that model, looks to be off a 550F.

Top hat missing from headlight screws, Graham does some nice stainless ones Ted.

Shame the tanks dented, looks nice.

Not being critical or picking holes in it Ted, just pointing out some small things you would be advised to fix. You can keep the left hand switchgear though if it works, does it have the headlight flasher?

Let me know if I can help with anything.

Nice project Ted! Good luck, we look forward to updates. (Check clock mounting bracket, bent or loose) maybe just the angle but look as if they are sitting flatter than the norm.

You probably want to check the bottom yoke and lock stops; it looks as though the headlamp ears have clouded the tank?

Is it a USA model? The clocks look like the ‘small type’ flatter presentation with odometer adjustment on the side rather than underneath. My comparison is based on a 1973K2, which may not be relevant. Dunno. Bit it looks to be substantially all there more or less. Definitely a good start.
Title: Re: My next project a CB500 K1 circa 1972 has arrived.
Post by: Bryanj on September 11, 2022, 09:01:43 AM
The clocks are correct for the K0 and 1, the K2 was a US model with bigger clocks and the trip knob downwards. The US K1 had a bracket that angled the clocks more towards the rider and full chrome backs instead of the open ones.
I explained to Ted that this was not a restored bike and was built for a specific reasom with the most useable bits i had acess to at the time and we were both happy with the bike and price.
Roo was very kind in transporting it as i no longer have a vehicle with towbar and even when his initial reason for going that way fell through still transported the bike for Ted.
I am more than happy to give reasons for anything seen and me and Ted have agreements that we wont discuss here.

I should think Ted is well satisfied with that. An honest, unpretentious example ripe for strategic attention. Wish I’d bought a more substantially complete 550- Finding some parts was a real headache.

I was responding to the earlier suggestion it was a US model….not that it really matters IMHO- they are all Japanese exports.

Good luck Ted. You have got to take the motor apart….it’s mandatory 😀

Great lttle bike, really honest and Ted was super chuffed with it. Also, for somebody buying one of these old bikes, he fired it last night and it ran on all four!!!

Ive only ever bought two bikes that have run on four when I bought them. And one of those was a Ducati ;D



Great to meet Ted and Wendy yesterday, I had a fantastic couple of coffes there and a good giggle.I know who wears the trousers ;D ;D ;D (sorry Ted)


What great folk, brilliant to meet them both. I'd have bought that had I the dosh and a shed not full of machinery in bits ;D I know Ted will love working on that this winter its a lovely little bike that.

Cant believe that Bryan threw the cobwebs and arachnids  in FOC, he's obviously mellowing in his old age ;) :D

Thanks for your observations Ken you are correct neither D washer is in place -  wow aren't they pricey at £8.88each at DS.
No pass switch fitted but everything works - well I can hear the horn click once but not sound.lol
No top hats on headlamps.
The tank needs painting as it has some scratch marks on the top & elsewhere.

A promising start I also cant see a fuse box just one added in line blade fuse ??

Fooled me with that one Bryan. The grabrail threw me as I knew the UK didn't get one. Looks to be off a 550 as well as they are higher at the back than the 500 grabrails.

500 only ever had a single inline fuse Ted, it was a big mistake by Honda IMO, if it blows EVERYTHING dies, engine included. If you can't find what's causing the blow you're stranded. The 550 has much better electrics which was why I fitted a 550 loom to my 500.

You must be super chuffed Ted. Great starting point for a bike that you can build to your spec. We shouldn't get hung up on everything being as it came out of the factory and should build a bike that you are happy with. My 750 and 500 look standard to the average model admirer but could be pulled apart by model experts (UK handlebars/indicators on US 500K2) plus stainless bolts throughout. But it's what I want!
Big advantage is you know it's background and it comes from an expert - a luxury most of us never have when buying a 50 year old bike. Good luck and enjoy the build.
They are great bikes!

Although the 500 is a runner I need to find out if it's a rider.
I'm going to take the back wheel out as it's binding I suspect due to some rusting in the hub area. The throttle movement is quite stiff even though the carbs have been refurbished - not sure if it's the twist grip or the cables so I need to fix that plus reduce the front brake lever travel before I ride her on the road.
This is plan A before the strip down starts.

No I wanted to see if Bryan could check it for me that's why it was aboard Ted. I bobbed into Brmingham to see a mate and drop her a few bits in for her bikes she has.

That piccy was this morning before I started faffing about.

It's more of a mechanical issue with the brake lever. There is about an inch of movement at the end of the lever before it starts to actuate the master cylinder - It does not feel like pivot pin wear just a load of movement that does nothing?
Once the lever meets the master cylinder the brake feel is as it should be. I did wonder if it's the right lever.

Post by: Bryanj on September 12, 2022, 10:23:22 AM
It was a pattern lever but there is only one type for the sohc, Goldwings have a different one.
The play was a common complaint back in the day, never really found a cure, i have heard of the yanks aralditing a dime on the end of the master piston

Post by: K2-K6 on September 12, 2022, 11:15:45 AM
Ted, I test hydraulic systems all the same to assess integrity ( this not to judge Bryan's competence) by squeezing the lever with both hands until you eyes bulge, or the lever touches the end of travel, multiple times.

In essence a proper "Gorilla" stress test that will find any failure to survive in safety. Ordinarily that's way above any in use pressure that it'll be subjected to and give confidence that the seals etc are working.

On the free travel though, something that I've never like and as Bryan indicated, some system seem to inherently have mechanical geometry that gives too much travel. Maybe someone else can help with example fro another 500 that agrees or dispels with this example. I've always used genuine Honda levers as not keen on material specs for many non oem types.

Post by: McCabe-Thiele (Ted) on September 12, 2022, 05:00:37 PM
I've had the back wheel out and sorted out the hub binding  - a very small dent in the hub flange edge  area was the culprit. Cut most of the alloy out with a Stanley Knife then a bit of polishing with a cutting wheel - cleaned brake shoe contact area plus roughed up the shoes a tad.

Next sort out the stiff throttle - just drained the tank prior to removal to get at the open & closing cables - seat removed to make it easier to access all areas.
Definitely need to look inside the engine for peace of mind.

On the subject of brake lever travel, I (and a good few other riders that I know from our evening bike meets) have found that replacing the original Honda master cylinder (smooth reservoir) with a pattern type (fluted reservoir) reduces lever travel immediately, for reasons that I am unsure of, but assume that perhaps the piston sizes differ slightly?

I have a DS replica on my 400 - there is virtually zero movement.
I'll try a spare original lever see how that is if it fits.

Most of the heavy throttle action was down to cable routing so that's one less item for now - needs a new throttle tube and grip for the rebuild but works well enough for now.
Nice chrome stopper in the handlebar end. - not sure if that's original.

Started first clean of the spare crank cases that Bryan has provided / lent me - boy was there some oil crud on the case halves. As I'm giving it some stiff brushing with petrol in a plastic box that the cases arrived in I realise petrol is leaking every where - the box has a split in the base!

My 400 has the fluted type that I bought from DS they list the same part for the 500. Clearly the lever on the DS part is right up against the piston when the lever is at rest with no floppy movement. The 500 piston is more rcessed plus the lever flops back as well. For a trial ride the brakes are solid enough but for the rebuild I will go for the DS one methinks.

Ted, for the throttle pipe I'd recommend buying one off a CB1300, 2003-2010. The ears where the cables connect is bigger so you get more pull for the same action, I tested it when trying to reduce the throttle movement the 500 is plagued with. It reduces the amount of twist you need to make by around 14% IIRC.

You could find one cheap on Ebay and the grips are good as well, don't get the 500 genuine grips, they are frankly awful, uncomfortable even with gloves on and without sheer agony to use. The 550F grips are far better and the 1300 grips look just like them.

If it has any cables coming out of it don't buy as it's hand heated grips fitted and you'd need the other side to match and the 500 couldn't run them anyway.

Post by: Oddjob on September 14, 2022, 02:09:21 PM
The 1300 throttle pipe comes with grip already attached so even though it's pricey if buying new at least you get both pipe and grip and buy the matching grip for the left side and it's acceptable for what you get. Plus the grips are nice, stylish and comfortable.

AND,

You don't need to order from DS, any Honda dealer will get them for you.

Presumably they are the same diameter handle bars the, do you have a part number for the 1300 option by any chance?

The bike is taxed & insured from  today only cost £26.99 to add the 500 to my Policy with Peter James.

Just fitting a spare horn as the existing one just clicks - tried the adjuster screw - result a louder single click.
Can't dismantle as it's rivetted together.
Throttle routing sorted using existing cables just need to sort the horn so it's road legal.

First ride before the weekend hopefully.

Amendment:- Spare horn fitted & operational. (Gawd it does sound a pathetic beep).

Post by: Oddjob on September 14, 2022, 06:21:26 PM
Yes Ted, same diameter bars and I also checked the extra height of the pipe ears fit the existing switches without fouling.

Part number is shown on that link I posted but just in case, part number 5 is 53140-MFP-N00 £28.55 and the corresponding grip to match is part No6, 53166-MFP-N00 at £15.90. Prices include VAT. Total £44.45. You can ring any local Honda dealer with those part numbers and pay over the phone, they'll advise when in stock and just one trip to pick them up.

As comparison, throttle pipe, 53141-300-010 is £16.08 , R/H grip 53165-390-780 is £12.12 and L/H grip 53166-390-780 is also £12.12. Total £40.32 plus £7 P&P DS charges. Reasonably comparable I'd say.

I was lucky in mine, I fitted genuine Honda heated grips to the 1300 and it came with throttle pipe included so I removed all those parts, thus my upgrade is free.

Ted, for the throttle pipe I'd recommend buying one off a CB1300, 2003-2010. The ears where the cables connect is bigger so you get more pull for the same action, I tested it when trying to reduce the throttle movement the 500 is plagued with. It reduces the amount of twist you need to make by around 14% IIRC.


I thought it was just me thinking the twist was ridiculous !! Cheers :)

The local Honda dealer was Bob Minions in Derby who is now selling Royal Enfields - nearest dealer is a good 20 miles away (None in Derby itself now) so cost more in fuel to drive over.

What is the test rig you refer to Ken?

Did a massive reply yesterday on my Ipad, was just about to press send when it just went off. 75% battery power and it said the battery was flat. Put it on charge and of course the reply is now gone.

So here goes again.

Test rig. Used my old genuine Honda handlebars, a genuine left hand switchgear and some old but good throttle cables. For the carbs I just used the frame with the butterfly on as carbs are not needed for this. I marked everything up at rest and then remarked when throttle fully open. Check reply 137 on this thread. http://www.sohc.co.uk/index.php/topic,19895.135.html It explains what I did and what the results were.

20 miles would be good to do the test run on the 500 Ted, but hey ho, it's your money and I can see why postage may be better.

Whilst you've got the left hand switchgear open have you checked to see if the throttle clamp is working. This is the large chrome screw under the switch and between the cables, when you wind it in the throttle stiffens up, which I can see you frowning thinking why would I want that, well on a motorway you can wind this screw in as you ride and the throttle will stay open at a set speed, all that pressure of holding the throttle open goes away, in case you need to shut off the throttle you just twist it and the return cable closes the throttle against the pressure of the clamp. The screw should have a chrome spring on but there is an internal ramp? which usually falls out when you open the switchgear and rolls away and you never notice it. Check to see if this ramp is there. It's a very handy bit of kit, can be used to set the tickover at 3000 to check the advance retard mechanism for instance, which is what Honda fitted it for IIRC. The 750 and the 500 got this clamp, the 550 did not. However everything on the 550 switchgear is there except the drilling for the screw, I converted my 550 switchgear to fit one as I use it a lot.

I've ordered the 1300 grip & grip tube for the LHS.

Can't ride my 500 today as it's stuck on my bike stand - on it's centre stand - either my brother or a friend will have to help me get it off safely.

On my 400 I could stradle the bike on the stand, put my left foot on the stand lever and push forwards pulling on the front brake before the front wheel hits the front stop plate - the 500 is heavier plus the lever is higher off the ground I just can't hold the stand with my left foot the whole bike moves forward instead on the darn ramp base. It might be the centre stand pivot is a little seized.

I've tried putting a long piece of wood between the ramp end & the foot of the cente stand but it's just does not quite come off the stand. Not worth risking me falling over with the bike trying to do it alone - or even worse the bike falling on Wendy's car in the garage -

Ted, the 500 is my baby, I've done things to 500s that most others haven't even thought of. One of the things is fitting the centre stand with a grease nipple. Now the tube of the centre stand isn't thick enough to take a nipple without it fouling the pin, so what I did was drill a 5mm hole central on the tube, in a location that I knew I could get a grease gun to when it's fitted and where there was little chance of it fouling anything. Tap the hole to 6mm and flat spot the tube, insert a 6mm bolt with a nut on, flanged might work better but mine was just a plain nut. Thread the bolt into the hole and then tighten the nut down onto the flat spot. Get it welded there, a seam weld so grease doesn't escape when the pressure is on. Remove the bolt after and using a 6mm copper washer fit a grease nipple. A few quick squeezes once a year and the stand will never seize again, it rolls on and off like it's not even there. You can do the hole 4mm and use a 5mm nipple if you so choose and stainless nipples are now readily available when they weren't when I first did this back in the late 70s.

I fitted grease nipples all over the bike, the rear brake pivot tube for the brake lever has one, both front caliper mounts have them, swinging arm got a central grease nipple to improve the way the bushes got greased, even the headstock got one, I can grease the taper rollers without taking the bike apart.

I have further plans to improve the side stand and make it cut the engine out if you set off with it down (and you will do this, everyone has), lots of ideas, some good, some just weird.

Thanks again Ken for the advice I'll look at doing something similar when doing the strip down.

Good news young Marco (I got him through his driving test almost 5 yrs ago) dropped by on his way home from work to help me get the bike safely off the ramp.

You’re just teasing us….

You have shamed me into a first ride now I'm back home from my appointment Philip.

After a tin of Popeye's best spinach I rode around the estate at the back to see how I managed - it felt as heavy as my old XJ 900 as I pootled round the block only got as far as third gear due to traffic, speed limit, seemingly poor  heavy front brake plus  rear pedal is a tad low. My feet seem too big I keep on striking the alternator housing with my size 12's- shame its not heel & toe shift.

The bike certainly fits me better in terms of comfort / height - it seems to have a lot more grunt/torque than my 400.  As the bike has been standing it might be prudent for me to check the caliper piston operation before I do another run to get into top gear. 

A promising start from my perspective. It reminded me of when I first rode my Triumph 21 when I was 19/20.

BP & Pulse back to normal.

Moving the splines may not be the answer though Ted. Honda used punch marks so as to make it easy to not only get the mechanism right but also to highlight when it had a problem.

If the punch marks line up, not only on the brake pedal and brake spindle but also on the brake drum arm and it’s spindle and things still don’t feel right it shows that somewhere there’s a problem. It could be worn brake shoes or the pivot pin has excessive play or one of the levers is bent etc so just moving the splines may in fact cover up the fault.

The brake shoes look very new with naff all wear I'll check the punch mark & follow your diagnosis advice. Not likely to do much before Tuesday as the Gaffer is at home & shopping beckons. (sigh)

Update:-  Managed to sneak a look at the bike - the rear brake levershaft  dots are just one half spline out - if I rotate the lever just one spline anticlockwise it will be sorted. Must have felt stronger today as I managed to get the 500 on the centre stand without drama this morning after resting overnight on the side stand. (The bike not me)

Ted its a knack, you stand on the centre stand with one foot(usualy right)and rock backwards lifting on grab rail at same time. The brake shoes were new pattern but had to be shaved a bit as i think that was a relined rear hub, not 100% sure as i had 3 done umptiy didly twelve years ago. That means they will probably need a bit extra bedding in to work 100%

Yesterday I tried the same method to get it on the centre stand after 3 fails it was on the side stand overnight. This morning same way as yesterday - left hand on the bars, right hand on the rear rail, pressed down with my right foot - straight up on the stand.

I know life is a series of challenges but today did not quite end as I planned.

Last Friday 16th Sept 2022 I managed to get round the block at the back but due to a lack of safe braking I returned home only managing to get as high as 3rd gear. I did not mention previously that as I turned into my drive the engine stalled at my gates.

After opening the gates the bike did not want to restart so I was forced to walk it up ino my garage with leg power. I then noticed that the choke was fully on in the up position. Choke off and she fired up okay.

Today I had lunch out with my brother I stuck to alcohol free beer as I had a longer ride out planned this afternoon. Bike started up so initially I thought a short ride around the estate to try the brakes out before the test ride propper.

I started off well with some extra revving to keep the engine going as it was warming up. As I rode round the block  it was running progressively worse so decided to return home. Once again the engine struggled to keep going as I turned into my driveway where it conked out. The choke was once again the culprit being in the fully on position.

I'm not sure why the choke comes on - could be I catch it with my boots when changing gear?

Is this something others here have had an issue with - I might need to put a rubber band on it somehow to stop accidental operation. The engine is now misfiring so I will need to clean the plugs again and try again at the weekend.

Post by: Oddjob on September 23, 2022, 04:58:30 PM
Does the choke move and open/close with a sort of click Ted?

There is a small spring and ball bearing fitted behind the lever, if it's been left out on the rebuild the lever will essentially just move under the vibration of the engine. There are small indents on the back of the choke lever for the ball bearing to go into at fully open/close, you should hear the click as the bearing locates at both these positions.

I has however been known for boots to close the choke as you ride as you suggest, just check where the boots are in relation to the choke lever and see if it looks a possibility

Post by: McCabe-Thiele (Ted) on September 23, 2022, 05:11:37 PM
Yes Ken the choke does have a nice click when fully off  - Bryan had them restored (Gerben?) about 12-18 months ago- just gone out into the garage with boot in hand - with the boot on the foorest the top part is almost level with the lever.

Its a series or four/five  roads round the block with lots of up & down on the approaches to give ways. On my 400 the choke is much higher up & out of the way so not a problem.

Even Gerben cam make a mistake Ted. Always worth checking.

As for the boot, you may have to alter your riding position a bit or wear shorter boots. I've got some Marc Marquez ankle boots by Alpine Star and find them really comfortable, much more so then my Sidi boots.

I struggle with the gear upshift due to my size 12 feet in my Daytonas - not sure if I can shift the lever a bit lower down on the splines.

On my 500/4 I found it impossible to ride the bike with full - length boots, due to the choke activating on some upshifts - not what you want when overtaking! (I'm a size 10, by the way).

The answer was to wear only ankle boots when using it, something that I found so comfortable that my new full - length boots remain virtually unused, except in very cold weather or when touring.

By chance, I ended up fitting a 750-gear lever on the 500 as the splines became worn on the original and I had a 750 lever in my box of spares. I subsequently found that, after riding my BMW and jumping straight on to the 500 in full - length boots, it had cured the tendency for me to catch the choke lever on upshifts - something that you might like to try yourself?

Finally went out on the 500 this morning without any drama - choke lever fixed in the OFF position with a narrow cable tie for now.

All five gears were good - I did quite a bit of accelerating & gentle braking to get the front pads settled - brakes got better with every application as the pads warmed up a little. Most importantly my hips were fine - it felt an easier ride than the 400 with the extra torque as you would expect.

A 10 mile road trip revealed a few things to look at during the re-build - an odd clonk from the front suspension area - plenty of general clatter from the engine but nothing too sinister sounding.
I'm thinking cam chain & primary drive chain & clutch area noises to my semi-trained ears plus a noisy exhuast blow near the silencer joint area.

Not that there was really ever any doubt - the engine will need stripping down it will be a few months before I start in earnest as I want to finish my 400 spare carb rebuild and put a few more miles on my 400 before the cold & rain sets in. I'll do a compression test beforehand to get a datum point. The engine pulls very well despite the above only wound her up to 60 mph briefly to feel the burn. lol

Looks like the oil filter has collapsed, had the same thing happen to me although mine almost covered the mesh. Check the filter and see if it has deformed, mine spiraled like someone had wrung it out. That's what you get for using non Honda filters.

When removing the filter Ted, don't forget that the spring has a large washer on top of it that gets stuck to the rubber of the filter and if you're not careful, thrown away with it.

Certainly not supposed to be there Ted, and looks similar to some filter material.

However, the oil filter is only in line supply from oil pump and out through the pressured points at crankshaft etc. Makes me wonder if that's possible to pass so much material (is it more or less one piece) through an entire system without blocking it. Perhaps I've missed something along the way.

As Ken says, inspection of the filter may give a clue, but I can't immediately see it all going through that system to arrive at the sump in first place.

The material completely covered the gauze - as the black sludge fell off it clumped into the bunch in the photo.

I'm going to investigate the filter but of course it could have come from a previous one.

Update: The filter I just removed looked fine - looks like a build up from previous filter(s).

Mine went completely through the system as it ended up exactly like Teds, it may be fibres pass through and then mat onto the mesh. I do know it resulted in oil pressure light flickering on/off and scoring of the oil pump rotor tips, luckily I spotted it as I had an oil pressure gauge fitted at the time so I was able to slow down to avoid a seizure.

Don't beat yourself up about it Bryan I have started refering to the "PO" not Bryan's old 500 - its a 50 year old bike that prior to yourself had a bunch of owners.

Good news for me is so far no seized bolts to contend with as the engine has clearly been stripped down before.

I felt like Popeye after his spinach when I got up this morning,
 
I have removed the camshaft that was in superb condition - the cylinder head came off pretty easily only odd thing was when I was undoing the head nuts in order I thought the socket was slipping on the nuts  - it made such a strange clicking noise as the nuts undid for the first half turn or so. After removinmg all the nuts & washers I squirted plenty of releasing fluid along the gasket line. A few taps with my big rubber mallet and it let go same with the block.

Most fidly bit was getting enough slack in the cam chain after undoing the  drive gear to lift out the camshaft. Even now I have not worked out how I finally managed to get the chain off the gear so it would feed through so as to speak. I did have to have a coffee break to overcome that hurdle.

Some decent vertical scoring on a couple of the piston skirts - the engine knew I was going to to end up inside.
Crankcase splitting will have to wait until I have some floor space and have put stuff into storage.
Engine lift out within a week is my plan A.

Never used freezer bags I use clear plastic takeaway boxes and some odd plastic woven boxes for bulky stuff (Wendy threw them out)

Cam covers, cylinder head & block go in a big black plastic box with old towels or bubble wrap to stop damage. I try to  arrange them in some sort of order on my garage shelves.

Today I have been searching for the alternator rotor end bolt without success. I'm eyeing the Chihuahuas as suspects.

The freezer bags are great as they have that slide fastening so you can open and close em as much as you like. I get them up to 18" long for the bigger bits. They come in mixed packs on flea bay for ablut 12 quid odd. I dont have the room for boxes so have everything separated into these bags and written on as to where and what it is and then goes into the main build box.

I have one tote for all new stuff and another full of the bagged bits ready to be cleaned, fettled, sworn at etc. they both sit under the bench when its up so works ok for me. i tried the take away containers but endedup with loads of lids and no bottoms so went back to the bags. Its the same place where I get those little tubs from that I sent that  snot in to you last month. Theyre god to and great in the sonic cleaner bath meaning you can do heaps all together without having to remember whats what after mixing it up.

I do have slight OCD though which might explain it. I haven't really done a huge amount over here yet, concentrating on cutting the hedge and getting the place tidy as i couldnt stand to look at it any more, it looked like someone had just stabbed it with a trimmer and I just HAD  to sort it!

I am a strange chap sometimes ;D ;D ;D

This is what was behind the fork ears the left one was worse rust extends down to the gaiters. - both front gaiters were split.

Looks bad even though some is  hidden behind the fork ears / headlamp brackets.

I am guessing that is an expensive fix.

Yes Ted, that's them. They collect and deliver as well. I would have thought with recent price increases, it'll be over £200 now. Turnaround is 4-6 weeks at the moment.

They do offer a dismantle and rebuild service Ted but you will be fine taking them apart. Also send them the top fork nuts as well and they will do them.

Post by: Oddjob on October 01, 2022, 02:37:25 PM
The bottom one looks to have a slight bend in it, Philpotts will correct that as well FOC

There is also Dynasurf in Sandbach, who are slightly cheaper but won't do the top nuts for free.

To save money Honda didn't chrome the stanchion under the fork ears, it wasn't seen so why bother, hence why they all look like that, some are a LOT worse.

Put a fork back into the yokes, clamp it up and then remove the 6mm allen key hidden under where the bottom end cap goes, do it BEFORE undoing the top nut, get it loose then undo the top nut. Repeat for other fork. You sometimes need a air hammer or impact gun to get the bottom allen key to shift, I suspect yours won't be that hard as they look to have been apart before.

I've removed the column from the frame can I just fit the yokes to the two fork tubes and clamp them off the frame to undo the bottom allen key bolt?

The top of the column has some damage where it has been clouted with a hammer sometime in the last 50 years - luckily the top thread is okay for the nut.

Not a great picture of the top bit.

Ted, I have just had the fork tubes done by Philpotts, took a while but perfect job. As they belong to Lazarus they were a lot worse than yours and i was unsure if they could be saved. Ring up philpotts and you will speak to a very nice lady who will arrange for collection next day and I was charged £215 all in inc delivery, and did my top nuts free. Only problem is if they are kinked, if so they wont do them for safety reasons.

Sounds a brilliant service I can't see any physical bend in them the photo & angle make them just look odd.

Not sure if it's damage or how they are - both fork ears have small creases on the inside. One is well pitted with rust the offside one is not bad.

Big bolt is the gearchange selector drum retaining bolt. It was used on early models to aid positive neutral selection.

The one circled is one of the 6 bolt holes and uses a 6 x 100mm flanged bolt.

Thanks Ken - a missing bolt then - no problem. Next I need to dismantle the primary gear drive as it's nothing like the 400.

Sharp rap on a piece of softwood will separate the primary drive to access the rubbers. This is where it gets interesting as many report the rubbers as being as hard as marble, but my 1977 17k miles example was as soft as originally installed, which is by the way not ‘soft’, just ‘compliant’. I replaced mine anyway as a matter of course. They ain’t cheap. That primary drive looks past its best by the way…..

I’d replace it Ted, but before you do try to evaluate the actual wear. This photo provides a simple visual check. The one in the background is a new Kawasaki item, the one in the foreground is 17k miles.

If you do replace the chain it would be useful for you to post a similar comparison just out of interest.

I convinced the BIL to replace the primary chain in my other 500 when he had it apart a few months ago. I had a spare Kwack chain so I sold him that one, 2 days later he's saying he's going to buy a new genuine one from DS as the Kwack fails the tank track test, which is what I called the method when I discovered it many moons ago, he's adamant he can get the chain to touch along a lot of the links. A new chain will touch but it really needs to be forced, whereas an old one will touch without even trying. I spent 5 minutes telling him he must be wrong, he's adamant he's not. After a while I asked him, are you testing on a flat surface, yes, you do have the chain on it's edge like a tank track? Silence. An embarrassed few seconds later and he admits he's been testing it lying on it's side, puts it on it's edge and of course it refuses to touch links. I wonder about him sometimes.

Fowlers has some in stock Ted. Cheap as well, sure they were dearer last time I bought a couple.

The casing that I am dismantling has crank codes BAAAA.
The mains coded A are Green bearings, no code at the moment for (B) mains 1.

The donor casing I have to use has crank codes AABBB.

Looks like I will have fun sorting out the new combination.

Green, Green, Brown, Brown, Brown.

That's the biggest shell allowance for the crankcase coding, A can only have had Yellow or Green from the factory, B can only have had Green or Brown. So chose the thickest of the 2 colours available and run it in carefully.

You do realise that if you go with brown you'll have people saying that's a really shit colour mate  ;D ;D ;D And they'd be right.

I've seen a couple of frames when going to pick my bits up from the powder coaters, one was Candy Blue and the other was Candy Purple like the old Fords, Aubergine I think it was called. Utterly stunning the pair of them, I was gobsmakced by how nice the blue one was, I even convinced myself to have mine done in that colour it was so nice. However it wouldn't suit the rest of the paintwork so I talked myself out of it.

I'm seriously considering having the 1300 frame done in Candy Apple Red, they did a model with a post office red frame in 2007, always liked it. Plus my 1300 is Pearlescent white with Candy red inserts so it would go really well with it.

I got my 500 parts book from a shop in Derby, I'd ridden down with the future missus and I'd bought and asked for so many parts that he asked if I was interested in buying a parts book to make it easier, cost me £5 and I still have it, it's really battered and tatty now and pages have come loose but I'd never swap it. It's even got some prices hand written against part numbers, which make me smile when I see them and compare them to todays prices.

Shop was a main Honda dealer, somewhere close to the city centre IIRC. I may recognise the name if you know it. Palins? maybe

There may have been two Honda Dealers as Bob Minion was a Honda Dealer for many decades 40 (plus firstly on Park St then London Rd) as was Samways when they were on the corner of Nuns Street & Mill Street before moving onto Ashbourne Road as Pedal Cycle only dealers they closed completely about 3/4 years ago.

I used to look into Samways showroom window looking at the new Honda CX500 for sale.
I have no memory of Palins being Honda though they may have replaced Samways.
Bob Minions is still going I think it's a son of Lionel Minion or Bob's that runs the site - now Royal Enfield & Royal Alloy.

Palins were definitely a main Honda dealer at one time. Would have been around 1976-7 when I was there, for some reason Osmaston Road keeps nagging me as the address, is that correct?

Definitely Palin's / Honda. Spent too much time and money there in the 70's and 80's.

Minions were Suzuki for sure in the main. Probably some Yams and Kwaks too?

Always thought of Samways as bicycles / small mopeds etc?  Probably wrong... Their slogan was "Samways for the Highways". Isn't the mind a wonder (even in the degenerated state mine is in)

I believe like car dealers most motor cycle dealerships in the 1960s were multi-franchise until later decades. I went to Samways for Triumph spares & Mackton Motors for Aerial when they were on Osmason Ted.

Google still shows Minions as Honda.

I had real trouble on my 550 removing the taper roller bearings as there is no space to get a long drift to knock them out, the bearing is the same diameter as the housing. In the end i had a mate put a bead of weld around it and it just fell out. Same problem now with Lazarus.
I removed the top bearing race at the bottom of the column today. I was very lucky with there being a small gap between the shoulder of the inside of the frame and the bearing. I found a bit of metal ( steel part of magnetic kitchen door catch) I was able to insert the metal plate into the column so it was jamed on both sides in the gap. With a long drift I gave the plate a whack close to the edge. Two taps on opposite corners it came out undamaged. An NTN 30x50x14 taper bearing race.

BiL visited and removed the bottom bearing from my headstock/column using what looked like a big clumsy puller - but it worked a treat!
It took longer to assemble the puller than to use it!

It was similar to the one in the link below - worked like a dream.

I just use a chisel and hit them upwards, never failed to work. Most times you’re doing this you binning the race to fit a new one so it doesn’t matter if it gets trashed but I did my taper rollers the other month and they’ll be going back on, no damage.

My 500/4 had the same damage to the lock stop and it was found on an MOT (albeit many years after it became mine, and the umpteenth MOT at the same dealer).

It didn't fail because the bars didn't touch the tank, although I replaced it as a matter of course when I renewed the steering head bearings as the differences in available lock left and right proved an irritation after the issue was pointed out to me.

They bend if the bike falls off it's sidestsnd when stationary, not particularly strong.

It's usually the right one bent when the bike is parked with bars to left and "rolls" off the stand, or not fully stood onto stand securely.

You can heat it to bend back, but don't quench it afterwards.

Different part numbers so yes Brian not the same.

With the bent steering stop, slight damage to the top of the column where the top nut fits - might be worth trying to find a better one.

That may be hot enough as you've only to get it glowing dull red to get it moving. The very tip of the blue flame is hottest and will let you target the stop easily to try it. There's at least no risk of going over temperature, just that it may soak the heat out into the rest of the structure fast enough to prevent that bit getting hot enough. You'll soon see though if it's possible (if you do it in dim light you'd see colour change more easily) and just tap it gently with a metal hammer.

Roughly if it's red temp you should be able to gently tap it, yellow and it would push with a drift but doubt you'll get it to yellow with just gas.

It's pretty safe as the only risk is not getting warm enough to move.

If you don't want to tap the metal directly, then just place a ring spanner over the peg loosely and you can tap that to move it.

Get a thread pitch finder like you can get in a tap and dye set, check what thread you have and the different sizes working surfaces are  written on each side of the file. When you use it you can feel when its working as you'll feel the vibrations and feels positive and you should see worked material dust on the vice underneath what youre working on. I only use it on a forward pushing stroke and have managed a 100% success rate. I bought a  brand new ecentric hub assembly for the VFR as the owner had cross threaded the big 50odd mm nut that goes in it really badly. Twenty minutes and it was as good as ever and now sitting on the bench ready to be fitted to the new rear arm I've had painted up ready to go on with the new shock and other gubbins I've got for it. Without the file the part was junk but its now virtually brand new.certainly looks it.

Every side is for a different pitch. Again, if you're not sure, get on You tube you'd be surprised what instruction you can find. ;) :)

Ted, I think that I have an undamaged top yoke for a 500/4. I replaced both on mine once the tester discovered that the lower was damaged on the lock stop.

If that's the case, you are welcome to it if you arrange collection from me (Norfolk). Previous experience does suggest that most carriers will allow you to organise it from your side, leaving me to simply pack it and hand to the courier.

Let me know and if you need it, I'll look in my stock of spares tomorrow.

Whatever happened to the "It's your bike, your build, your money, your choice ethos?"

I don't know why but brown just appeals to the retro look in my brain, when Ken sees the finished bike instead of itemising what's not original K1 he will just think -  crap colour it matches the rest of the  bike.
I'm not thinking outside the box more outside the closet/latrine.

Sorry Ted, you're right, it's your build and your choice. I'll be honest and say the brown colours on the 500 and 550 were frankly awful, I hated that colour, I've had quite a few 500s and 550s and never have I bought a brown one, had black and golds and blues and purple but never brown. It's just a personal thing, whilst we are being a bit cheeky and taking the piss a little bit, that's what friends do to other friends. There's no malice in it.

However I really do think an all brown bike is a poor choice, the 500T had a brown seat and it always looked like you'd shit yourself riding it. First impressions and all that.

Ken I'm jousting I'm not offended at all - if it wasn't for the fact that the bike colour is a brownish bronze colour I would not dream of a brown frame.

I like Apple Candy Red and Black. I take the frame tomorrow to the painters. Gawd knows what I will chose they have some colour samples so I might find something else or go for BB.

Whatever happened to the "It's your bike, your build, your money, your choice ethos?"


Sorry mate, only yanking yer chain like Ken said bt I'm with Ken, sorry mate. Bikes should never be brown. You do your best and have whatever lovely shade you want buddy, wait till you see the metal flake ORANGE I've gone for with a cream bottom border, youll laugh yer arse off. It looks like its come from a Baha beetle beach buggy, its that offensive ;D ;D.

Its going to look like a dodgem car so get yer ammo ready.

Enjoy the painters is always really interesting and you'll learn heaps so make sure you ask loads of questions ;) 8) 8) 8)

For me it's that the frame is no "looker" in design or detailed execution, and doesn't need attention drawing to it.

Nota a Bridget Bardot

Or for balance/diversity/framework, a David Gandypants  ;D

To demonstrate framework

The bikes are lovely looking and fabulous as a whole, but having frame lighter than the paintwork just seems to draw attention to the less aesthetically appealing aspect.

You make a good point K2-K6 about a lighter colour drawing attention to the frame.
I think I got away with it on my 400 but the 500 especially if it ever gets the original silencers is a very different kettle of fish.

Agree Ted, the 400 was a shift in style to more modern with tank and seat form being noticeably a step away from earlier traditional drawing of these 4 cylinder Honda. They seem to take on colours more easily as they originally were those very plain tank colours without real embellishment, also the pipe "display" being front predominantly.

The 4 pipers are all about the display of those pipes to give the character from that era. Obviously very personal choice to make and a little difficult to fully visualise at this stage. Hope you get what you want as it's always nice to own something that you can just look at and be very pleased with, especially given the cost and effort put into it.

I do like brown, with many of the original paint schemes on these having that colour pallet (technically the golds are really a lighter brown in colour spectrum) it's prediction of ultimate combination that's a trial and error.

Coincidentally I've recently bought a mtb cycle frame in that very dark metallic brown with manufacturer logo in black, a very nicely made aluminium welded structure that looks spectacularly good as it shows that element off so well.

Hope you can decide by the time you reach the paint shop  :)

Thank you everyone for talking me out of Nut Brown - when I looked at the colour sample swatch it was too light in the daylight anyways - they had no very dark browns like I fancied.
I even went to my brothers yesterday to look at one of his brown pedal cycles - an early Carlton - it looked pretty good.

In the end I chose the dullest 30% Gloss Black.

Oh NO, NO, NO, NO BORING BLACK has won ;D ;D ;D

It does give me more freedom of choice when it comes to painting the tank & side panels - at the moment I'm inclined to go for Black like Simons even though I love the Candy Reds.

 ;D ;D yes Ken I know it must be a shock when people find out it's not real gold. A little like a pools winner's bath taps  ;D

Interestingly, when you think about it these era Honda are all monochromatic originally.  With black, white, chrome etc all having no "colour" and just the candy paint to offset that, giving such prominent impact to that single colour. They are really striking with this effect though.

Finally I've finished removing all old gasket material from the engine casings - they have been cleaned inside & out using Petrol wash applied with a paint brush.

Next step is to strip the paint from the engine casings hopefully starting on Monday if it is not raining as I need to be outside when I apply & eventually hose it off directly into the sewer manhole.
I put on all my safety gear as the Industrial Grade stuff is nasty -  then apply my first coat of Paramose paint stripper.

Despite all my safety gear when I finish an item & return to the house minus my gloves, mask, eye & face  protection for a coffee I always feel itchy and end up washing my hands & face!
Probably a combination of fear sweat & my imagination. (I hope)

I'm lucky Roo only ever had a verbal caution during the fuel crisis back in the 1970s when it was 50 mph maximum.

That said I've had a few parking tickets - two on the same day one where the rear of my Mini was 1ft over the double yellows. I've only ever won one appeal when Wendy parked for over 30 mins in a drop off zone - she was dropping her Dad off when he accidentally touched the door lock button as she was helping him out of the passenger side. Key was in the ignition - it took me 40 mins to find the spare key and drive to Burton Hospital to unlock her car.

A lot of Police forces, including here in Lincs have recently done away with, or are doing away with the 10% rule. If the speed limit is 30, they say that is the maximum speed and you should be under it anyway, not 10% over.
The 10% rule was only a recommendation anyway, which is fine if its a real Poice person that catches you but all these automatic speed trap cameras can't use their judgement.

Post by: McCabe-Thiele (Ted) on October 15, 2022, 05:20:42 PM
The 10 % rule was written into the Construction & Use regulations decades ago - effectively saying a vehicles speedometer had to be accurate within 10 %. This you means you have to exceed the 30 mph limit by 3 mph to commit an offence.
What causes confusion is they have deducted the. 10% from the figure already. Similarly the drink drive limit is 35 milligrammes of alcohol per 100 ml of blood - but only prosecute at 40 or above - the exception might occur in the case of a fatal accident when you might blow 38 on the machine when in theory they could go for impairment due to  alcohol rather than over the prescribed limit.

Used to be +or- 10% of actual speed but now is +0 to -10%.

The law makes it a clear as mud (see below) - when I last workded in Police Prosecutions in 1990 we worked on the 10% rule - then ACPO said differently on policy introducing zero tollerance via the back door. In reality most prosecutions ignored the ACPO decision & worked on the old 10% figure.  This avoided arguments over older cars that had speedometers that complied with previous Con & Use Regs.

Thing is if you pay the fixed penalty then the legality of speeding is never verified as you have admitted the offence when you pay the ticket or accept a Speed awareness course. It's not until until you engage the services of a Mr Loophole and plead not guilty at the Magistrates court that the truth emerges.


United Kingdom

The amended Road Vehicles (Construction and Use) Regulations 1986 permits the use of speedometers that meet either the requirements of EC Council Directive 75/443 (as amended by Directive 97/39) or UNECE Regulation 39.[17]

The Motor Vehicles (Approval) Regulations 2001[18] permits single vehicles to be approved. As with the UNECE regulation and the EC Directives, the speedometer must never show an indicated speed less than the actual speed. However, it differs slightly from them in specifying that for all actual speeds between 25 mph and 70 mph (or the vehicles' maximum speed if it is lower than this), the indicated speed must not exceed 110% of the actual speed, plus 6.25 mph.

For example, if the vehicle is actually traveling at 50 mph, the speedometer must not show more than 61.25 mph or less than 50 mph.

It was always the case that you could refuse to accept the fixed penalty notice and elect for a not guilty plea at the Magistrates Court - effectly a trial at the Magistrates bench either a Stipendiary sitting alone or 3 ley Magistrates. Subsequent conviction at a Magistrates  Court would be appealed at the Crown Court. I've been retired for 19 years so maybe things have changed but it is a summary offence only not an either way offence.
What can confuse folk is when they go to court it's often a Combined Court Building that houses both Magistrates Courts, Family Courts and probably now a Crown Court in the same  building.

Casings have had the first two petrol washes, next it's paint stripping, then surface preparation for painting, a full internal clean again including galleries & threads with suitable bottle brushes.

Plenty to keep me busy for a couple of weeks before I paint them.

Picked the frame up from the powder coaters today - good thing  is you can still see the stamped frame number.
Used a different powder coater this time RPT Engineering Ltd at Somercoates DE55 4LS Cost with VAT was £190 including stands, swing arm, battery box & rear frame grab rail part. 

Not as thickly applied this time so well pleased with the  30% gloss black finish.

A little more progress this afternoon - rear swing arm Brass bushes fitted plus shocker mount bushes - a couple of days in the freezer made the first 75% of the fitting easy - then use alloy drift tool and a big rubber hammer they fitted far too easily.

Spent a good 30 minutes looking for the rear brake pivot that I finally found in a takeaway box with rear brake pivot written on it. Work has ground to a standstill now until I find the return spring that was not in the box.

DS say its discontinued so another day for that search party - I have a feeling I put it somewhere too safe to find easily - keeps me fit I guess looking in the same places as before several times over.

Run out of beer so having to drink some Pineapple & Passion Fruit Cider (4%) to make do for tonight.

No - I am looking for a circular spring I take it 46514-323-020  I assume - found the pedal & the rod definitely a job for another day I must have looked in three shelves of boxes plus umpteen big boxes on the floor four times over - at least as you progress it gets easier with fewer parts to look through..

Fueled by Cider & a can of Mango flavoured Gin & Tonic I've had one last search - I  found the missing brake pedal return spring in a box I had looked through at least 4 times that mainly contained old 400 parts!
That just leaves one gearshift fork spring left to find that against all logic shot into the air as I was dismantling the gearbox - at least you can buy them cheap enough from Mr Silver.

Looking great Ted and you must be pleased with your progress. Just one observation on the powder coat job, which looks mighty fine by the way. Is that surface corrosion on the bottom r/h side rail between the foot rest and lower engine mount or just an optical illusion? Just wondering about a potential structural weak point in the frame that I have absolutely no knowledge off, but others on the forum may wish to comment…..just in the interests of safety you understand.

I'm pretty sure it's a combination of poor lighting & odd reflections.
I will look again and post a better picture - the frame looks like a scrapper when you zoom in. :-\



It was mainly dust plus copperslip you can still see some of it - there not dents in the tubing its a reflection of the rubber mat!

Might be a fire hazard when it's powder coated in the future.

I attended a garage fire back in the 1979/80 where an enthusiast was carrying out some electric welding on his beautiful Vauxhall PA Cresta. The POs Waxoyl caught fire gutting the interior. The poor chap was in tears it was in that lovely two tone Silver Sage combination.

Fitted Tee Shirt & Video ?

Anyways the return spring I found is not the correct one - it's the old one for my 400 that I replaced.

Done another sweep of the garage and failed to find the brake pedal spring plus the stop lamp switch they are together somewhere no doubt.
Can't fit the swing arm until I find it or a replacement!

Found the rear brake switch & its spring with the ignition wiring - no trace of the brake pedal return spring afetr another fruitless 40 minutes looking in everyone of my parts boxes.......sigh.

I’d replace it Ted, but before you do try to evaluate the actual wear. This photo provides a simple visual check. The one in the background is a new Kawasaki item, the one in the foreground is 17k miles.

If you do replace the chain it would be useful for you to post a similar comparison just out of interest.


A bit late in the day Phillip but this is my tank track from the 500.

I have fitted the two outer races into the steering column today - made up a nifty tool using threaded bar & alloy drift  discs to avoid all the hammering especially for the bottom race as the frame has the back wheel in place to support everyting safely. Fitted the top bearing first - partially in place so it was square then pulled into place - repeated for the bottom race - tool was easy to tighten up. One of the drift discs was just the right diameter to fit in the lower column & seat on the bearing.

Both races were fresh out of the Freezer when fitting.

Photo is after the bearings have been pulled into place - slack in the threaded bar so top is not shown as central but it was when tightening the nuts.

Probably was not needed but to help with centralisation I put some big washers in place to help with general centering of the tool - small enough to fit through the races but big enough to help.

Always nice when things go to plan.

Note to Ken the outer races are the right way up btw!

I have no idea - Bryan might know the answer - it's not the original alloy plate as is obviousy been hand engraved from a blank to match the headstock stamping.
The headstock stamped frame number it's the same as the V5 1030*** first  regd 23-3-1972. So what does it being a KO change assuming you are correct?

The engine number starts with a 2 - I was advised it was not the original engine by Bryan.

AFAIK the K1 had the frames and engine numbers starting with a 2 not a 1 which was how you could tell from the K0 version. It's possible it's had a new frame fitted at some point OR it could have had a K0 frame fitted by the factory but I'm doubtful about that, the frames were essentially the same so it's not a big issue, just a curiosity. Have you checked the frame itself for the stamped number on the headstock? to make sure they match.

Ken, the frame and V5 came to me in a "job lot" from either London or Liverpool, cant remember which as i did a grand tour collecting bikes and bits after putting an add in Classic Bike for parts wanted and getting a few answers. Absolutely no chance of remembering where from as it was before i got together with my now wife and weve been together over 20 years.
I engraved and fitted the vin plate as the stampings were not that "heavy" and i reckoned they would be damn near invisible whe$ powdered. I thought the 1 was K0 and 1 and the 2 was K2, which we never officialy got but Honda carried on the numerical order by year, i will look in my id book, which admitedley is US and post a pic of the page later.

The stamped headstock frame number matches the V5.
The V5 only reflects the numbers someone informed DVLA  of. If you inform DVLA of an engine or frame change, they change the numbers on the system and the V5 is changed to reflect that. It doesn't mean the engine and/or frame numbers are the originals they left the factory with.
Edit.. I should have said does it really matter in your case anyway Ted? Its not as if you are restoring a bike to standard spec or concours. My Mongrel build Millie is a 550 K3 frame with an 550 F2 engine and I don't loose any sleep over it. If it were a miss matched pair on one of my 'proper bikes' then I would worry 😁😁😁

On the riveted on frame plate the date of manufacture has been entered as 8/71.

You are right Julie I'm not fussed if the frame is a K0 or a K1 I'm happy that the frame is in good solid condition clearly having benefitted by Bryan getting the frame powder coated plus it's been his bike since June 2003.

If it is a K0 frame will this make any difference when obtaining parts? Are there easy ways to see the difference as regards the frame design?

So if its got a rivited VIN plate on it it's a USA frame as we didn't have the VIN plates on UK bikes until 1976. The easiest way to tell if its a K0 or K1 frame is to show us a photo of the seat lock assembly as they are totally different K0 to K1.
Here is our K0 seat lock. The K1 has a totally different design, it's a normal plunger type lock.

Whilst Julie is 100% right in pointing out that the biggest difference between the K0 and K1 was the seat lock I’m not sure if the K1 seat lock bracket wouldn’t also fit the K0 and vice versa. There is a slight change in the part number for the frame from 130B to 140B but whether the difference was in the positioning of the holes for that bracket or something else I couldn’t say.

My comment wasn’t meant to criticise the frame, it was to ask why when the title says K1 is it wearing a K0 frame, seemed odd. I’d imagine an 8/71 build date would also mean it’s a K0 rather than a K1.

It seems that K0 models are worth more as well, so a set of K0 cases may increase its value, need an engine number beginning with a 1 though Ted. The K1 engines all began with a 2. Strangely the K2 didn’t start with a 3, which you think would be the case. Both my K1 bikes have frames and engine numbers beginning with a 2 and the L reg bike has a build date of 5/72, so your frame being much earlier than that must mean a K0.

It’s not important as you say though, it’s just odd.

I had 2 sets of engine cases spare from way back in the 70-80s and both began with a 1, which is very odd as I never had or broke a K0 but I did buy quite a lot of broken engines back then but how they both ended up coming from a model that was never officially imported into the UK is strange.

I still have a set spare if you ever want to make the bike into a K0.

Yes the seat lock brackets interchange, it was fitted with a later type lock as the best recovered seat i had was a later type, dont know what was original as nothing was on it.
Julie, i fitted the vin plate and had to drill holes for it as i said above the stampings would disapear under powder coat.

FWIW the later seat lock does not quite sit flat on the frame like my 400 one does.

Yes the seat lock brackets interchange, it was fitted with a later type lock as the best recovered seat i had was a later type, dont know what was original as nothing was on it.
Julie, i fitted the vin plate and had to drill holes for it as i said above the stampings would disapear under powder coat.
Ah yes, I've just read about the VIN tag on a previous post Bryan, sorry about that. Ted, on the V5 what date does it give as being registered in UK?


                 

The V5 shows B. Date of first registration as 23 03 1972
   [B,1]Date of first registration in the UK as 23 03 1972

FWIW the later seat lock does not quite sit flat on the frame like my 400 one does.

It needs a little fettling on one area before I fit it back on.

Could be the bracket is slightly bent Ted, or of course it could also be the difference between the K0 and K1 frames coming into play. Hard to tell without testing another bracket and seeing if that does the same.

With a first reg date of March 72 it looks like the bike was what is called a "Grey Import".

Agreed, its a 71 build registered in UK in March 72.Therefore its either an original UK K0 or most likely a grey import.
There are a lot of differences between K0 and K1 but as you say Ted, you're building a mongrel, so it doesn't matter. If you were to try and restore it to a stock UK K0, it will cost a fortune. It also shouldn't have a VIN plate, but I can see Bryan's reason for fitting one.
Title: Re: Teds new project a CB500 K0 circa 1972.
Post by: Oddjob on November 28, 2022, 03:04:26 PM
I'd agree with that Ted. If the bike already had a lot of K0 parts fitted then I'd say it may be worthwhile to convert it back but that doesn't appear to be the case. The differences whilst not extreme were subtle but easy to spot if you knew what to look for, most people don't and TBH it doesn't matter anyway.

Officially Honda never imported the K0, I asked back in the late 70s when on a course at Honda and spoke to a few of the guys there, they said that Honda only ever officially imported 3 500K0s. One black, one brown and one gold, these were all for press testing. One was written off whilst on test, one was scrapped (no one knew why) and one was sold to a member of staff, they seemed to think it was the brown one. So unless yours is that one (and with that frame number it's almost impossible, the first ones imported would have had very low frame numbers I'd imagine) it's not meant to be here and was clearly meant for the European market. However interest in the 500 back then was high so some dealers imported some from contacts on the continent and hence were called grey imports. There won't have been that many imported like that as expense for one would not have made it commercially viable especially as the K1 was already on it's way. A genuine UK first registered 500K0 is a bit of a rarity so I'd be proud of that, not many about especially after all these years.

Noooo Ken, I'm not saying that, I didn't imply that and I didn't mean that, we have all our frames powder coated. But Ted went for a more satin finish IIRC which would be a no no.

Yeah but it's black, does that really matter. We do our yokes in satin and I'm fairly sure they came in gloss for instance or vice versa. We have repaints where we have the stripes painted on and not transfers, we use stainless spokes instead of crap normal steel ones that rust for fun, loads of examples like that.

IMO, we place far too much emphasis on it being exactly like it was when it came out of the factory and frankly that's virtually impossible, unless you've got one stored in a packing crate somewhere there will always be something that's not original fitment. If it works, look right and goes and stops right that's good enough for me.

It may be good enough for you Ken but not for everyone.

When I said it looks right I meant does it still look original, would anyone not an anal expert comment on something not fitted as standard?

If you've just spent the last year or so restoring a bike to OE spec and someone came along and started to rip it to bits how would that make you feel. Comments like, Those tyres are wrong, should be Bridgestones, the master cylinder wasn't quite that shape, is that a copy, you've repainted the handlebar switchgear and the colour of the letters is the wrong shade of red etc. You'd quite rightly tell them that all that doesn't matter so long as it looks the part, tyres were changed because new tyres work where the Bridgestones were just ditch finders.

I prefer to build mine so they look original but I don't like to repeat the mistakes Honda made in the first place, rear dampers that worked like Pogo sticks, it was common in those days for the speedo or tacho needle to bounce around like mad, would we settle for that now? Do we have to accept a wiring loom where all the power runs through one fuse, if that blows you stop. I had a mate back in the late 70s who was killed by just this thing happening, fast lane of the motorway, doing 70 or so, not speeding, just tootling along like you do, fuse blew for some reason, we never found out why, he suddenly slows as the bike loses power, car behind doesn't expect it and hits him up the rear end at around 100mph, catapulting him off the bike, his helmet flew off and he landed on his face, ripped most of his face off, he was just 17. His dad had to identify him in the morgue and it broke him, first of our gang to die and to this day I still get upset remembering him and the waste of that life for such a simple reason. Car driver got off BTW even though he was speeding it was deemed an accident.

I think it's arrogant of anyone to try and inflict their ways of restoring on anyone, so it might be the wrong black, who cares, it's black. Would you really notice if it was next to you at the lights? BTW Ted, we'd notice a nut brown frame, just saying  ;D ;D However if Ted had done the frame nut brown I might not have agreed with the choice but I'd certainly have admired the will to say "sod it, it's my bike I'll do it so I like it, if you don't, well hard luck"

Well done Ted,
looking at that top clamp on 'the net' last night, it's clear that the PG who had my 'heap' had cut the middle out to make two separate clamps. :o He's then ground them down badly, like a threepenny bit and tried to hide it with matt paint......eeesh! ;D Theyre smaller than the lower half of the clamp they sit on he's taken that much off........Lookslike I've doneit  ;D ;D

I knew they were for the bin but hadn't offered them up until last night when I pulled the bag out to have a look. They were chucked in the 'to fettle later' bin. As I'm still waiting for the frame from the coaters............Covid at their end................I said I'd hang on ;) :o I'm just prepping all the faff bits like this and sorting switches and the like...

Spent a lot of time bimbling about sorting out what bits were where - putting some parts in Evaporust etc.

It's much warmer today so I've been doing some work on both lower fork legs cleaning out the threads & the sediment inside the legs.
I need to do some more polishing on the right fork leg as ther left one is much shinier at the moment.
Once I am happy with the polishing of the fork legs I can get the front suspension fitted with a view to fitting the front wheel for better frame stability.

When the cold weather returns I can do some soldering on the Pilot light loom now I have some better lamp holders & rubber shroud fitting thingys.

Post by: Oddjob on December 20, 2022, 03:37:46 PM
Depends on what you already have Ted, you need a spare caliper and disc, a set of 550 sliders, a longer set of disc bolts and another part of the brake line. Not that expensive if you already have some of these. There's a little work involved as well adapting the speedo drive.

For me it's a good investment, if it stops you quicker it could just avoid an accident and those can be very expensive. 
Title: Re: Teds new project a CB500 K0 circa 1972.
Post by: Laverdaroo on December 20, 2022, 07:03:00 PM
Thats why I did it, for both those reasons. Looks far nicer for a bike of that size and braking is ony going to be improved as a result which just may be the deciding factor in a situation. The speedo drive isnt a biggie once you get your head round it. I had a spare disc floating about so apart from already having that the whole set up stands me at about 70 odd quid. Cheap win really.

I have a spare set of 550 fork lowers, and some 500 sliders that have just been re ground at Philpots and faultless, going on ebay after crimbo but if you need anything you have first dibbs Ted, goes without saying ;)

Post by: Oddjob on December 20, 2022, 07:13:42 PM
Don't forget you need to space out the caliper bolt on the new side Roo, if you don't the arm sits at an angle and the pads wear funny. It's because the new caliper mount sits ON the mudguard brace whereas the old side it sits under the brace, you also need to ensure the arm sits directly above the disc like the other side does. IIRC you need some washers between the top mount and the brace and a thicker one on the bottom mount bolt. I seem to recall I put the new caliper onto the new arm complete with pads, pushed it onto the rear of the disc not the front as that movable and left the bolts out, swung the arm until it was level with the mounting bolts and measured the gap. I ended up welding the washers to the brace and then having it chromed so I wouldn't lose them if I dismantled the front end.

Depends on what you already have Ted, you need a spare caliper and disc, a set of 550 sliders, a longer set of disc bolts and another part of the brake line. Not that expensive if you already have some of these. There's a little work involved as well adapting the speedo drive.

For me it's a good investment, if it stops you quicker it could just avoid an accident and those can be very expensive.

I have no spare caliper,disc or 550 sliders  not too woried about the look / accident risk for the mileage I am likely to cover. The Brembro pads certainly feel good so I'll keep that bit original.

Thinking about improvements / mods from the original  has made me re-think  the exhuast situation. I was minded to fit the original four pipe system to keep the period look and gloss over the cost. That got me thinking about the owners who went from twin pipe  to 4 into 1 systems  as they performed & sounded  better.

Just thought I would put that out there for added public humiliation to add to the Nut Brown saga - I still have regrets about settling for boring black.

I think after all the time and work you are putting in .... the original style system would be icing on the cake :)

I’ve had a few 4 into 1 systems Ted, a Piper system that howled like a Banshee having a prostate exam, had to remove it to change the oil filter though and it rusted for fun. A Yoshimura that was much quieter until you wound it up but it didn’t stop you working on the engine etc.

For best performance though the OE system takes some beating, sure the Yoshi performed better but only at the top end of the rev range, it lagged at mid range though, the Piper sounded better but it also had a hole in mid range, the 4 into 4 system looks awesome, it performs excellently and it just suits the look of the bike better.

For me it’s the exhausts that make the 500 so appealing, there’s just something about them that floats my boat in a BIG way.

Purists look away now - my DS Chrome finished plastic headlamp bowl & aftermaket rim kit arrived today so I was able to fit a neat Land Rover LED headlamp unit without any alterations.
Thanks for the tip Allankelly & the link. https://www.ebay.co.uk/itm/303960372602

Ted, nice h/lamp option. I want to build a bobber from many old Triumph 3T bits I have and this would fit the bill perfectly. Will look good on your 500.

Guys, spacing the calliper….I don’t recall having to do that? Do you mean spacing the caliper carrier pivot mounting on the fork bottom mounting?  I found using 2no 6mm washers sorted that. I’ll turn permanent spacers at some time in the future. Apologies if I’ve read that wrongly it’s just that I’ve got eye floaters again.

A work mate back in 1978/79 would give me a lift on his black 500 from York to Leeds. His was equipped with a Marvin 4:1. To my young ears it sounded mint, it really howled at the top end,  though he did complain of flat spots. He eventually changed back to standard. And I agree with Ken, the original 4 pipe appearance is best for the standard bike.
I’d even thought about putting 4 pipes on the F2, but the cost was prohibitive for an uncertain and unconventional appearance. I’ve gone for Dekelvic which is ok, but no substitute for standard.

Speaking of standard pipes, my CB175 pipes rotted out in 1977.  I tried all kinds of arrangements, but in order to make it run properly I eventually had to dig deep for standard replacements.

It's the long relatively small bore primary pipes that give the engine It's low to mid rpm torque. Mostly removed on 4:1 system, but doesn't need to be.

A friend drag raced a 750 years ago for which we tried sets of pipes, easily the fastest through initial phase and rpm range was a 4:1 with long thin primary pipes into short, stubby big bore less restricted "silencer" this for road orientated motor tune and not a really high revving race motor.
It takes alot of combustion volume/rpm to really make use of big bore short primary "headers" and mostly way outside capacity on bikes of this era.

Yes, I know all about that. I used some cheap reverse cone megaphones from that outfit in Rochdale- Unity Ill equipped or something like that. The noise was horrific. My mum asked me to coast or push the bike the last hundred yards after 10pm. I was able to reach back and place my boots over the ends so rarely bothered.

Fibreglass or Brillo pads…those were the days.

 I recall trying to pass from France to Switzerland in about 1980. We were sat patiently waiting for the border guard to put down his paper and coffee. While we waited a guy screamed up on a Yamaha 350 c/w expansion pipes. The BG dropped his paper and spilled his coffee in his haste to stop this hooligan entering Antiseptic land (the Swiss had and has very strict noise abatement laws), but before he could scream halt(in Swiss) the lad neatly navigated the barriers and sped off in a cloud of two stroke smoke. I got the distinct impression it was a regular occurrence. It’s the only funny thing I’ve witnessed in Switzerland. The guy who should have been stood at the barrier was having a leak and returned to a very red faced and loud colleague.

So after an absence over Christmas as SWMBO is out so I've spent  just under an hour this afternoon on each of my fork legs.

Used the light green then the grey little discs & finished up with some blue paste on my buffing wheel to see how they look spending just 5-10 mins with the buffing wheel using the lightest pressure as I don't want a fork leg in my face.

Clearly there are some deepish marks on the legs after 50 years but to hell with getting out every little imperfection - I will polish them some more but tbh I see the marks as a sort of Patina of age.

I'm unsure as yet what I'll be having done with my crankcases, I may do the same Ted (I also have the same AEG oven BTW) I may do that but I'm thinking of maybe putting a matt lacquer over the top which is petrol resistant, not 100% sure what would happen if that silver gets petrol on it. All you need is a carb overflow or a leak from a float bowl and if it all lifts it's an expensive fix.

Doing it yourself is miles cheaper though Roo.

As you know I dropped off a load of parts at the ceramic coaters on Wednesday, as one part wasn't mine I asked him to quote me for just those parts.

In the bag were the carb bracket where all the carbs mount, the 2 small lifter arms that go onto the rod and the 4 lifter boxes that sit inside the bank of carbs and rise when the throttle opens. All done is silver and lacquered over afterwards, cost was £50 to 7 bits. Got to be honest and say it was far more than I expected and I wasn't at all pleased. Especially as I had 2 of the carb brackets myself to be done, 6 exhaust clamps and 24 exhaust collets, 2 Brembo radial calipers, 2 1300 wheels plus a few other small pieces, gonna need a new mortgage if it's as expensive as I fear.

I'm feeling  suitably down hearted about the lack of side mounts - I've had quite a few bits from DK so hope they give me a refund as they seem to have a good reputation.

I trawled through most of the rear fenders they had in their shop concentrating on the number plate mounting points - missing the obvious lack of side mounts.

I feel the detail is appreciated here, though often used on mainstream sites to criticise a person........

I believe unconditional criticism toward someone that offers intricate details that are pertinent ordinarily display a lack of knowledge in the person delivering that critical view. It follows that the person without that knowledge feels vulnerable and insecure in the need to ridicule the one with knowledge.......from psychology in workplace environment study  8)

As the old front indicators were of different stem lengths with one being very rusty I bough myself a pair of aftermarket ones that are 30 mm longer.

Never mind the wind resistance just look at the King Charles stance.

I rather like the ears (thumbs up emoji). I wonder if you tilt them one way or the other you might get a bit of a 'chord' out of them as they catch the wind. Bit like a single church organ pipe ;D

Bars just in place nothing tightened up yet any lack of symmetry is a combination of camera angle & steering not being dead straight.

I've gone back a bit having stripped down the front forks to sort out a stripped thread on the left leg where the top calliper arm is fitted.

As a result I have found that the fork seal that are 35 x 48 x 11 has moved up on one side towards the circlip - there is what seems a big gap as though there ought to be a spacer between the seal & the circlip. When I fitted the seals they were flush at the bottom what's going on here?

Wonder if it’s bad fitting Ted? Cant see that it would shift touching against stanchion. Assuming they are correct seals for the job.
Maybe an attempt to get worn seals to seal?

They were new seals of the correct size for a 500  - they shifted when I was dismantling the forks -there was a substatntial gap 2-3 mm between the circlip in the groove when they were fitted fully down against the shoulder earlier in the year.

Bryan might be onto something about an alternative seal size being fitted.

According to parts book the seal should be 35 x 48 x 11, and from what has already told me that's what's printed on the seal. I do seem to recall some seals having a metal spacing washer fitted under the seal, snug fit inside the slider but bore too big for it to ever touch the stanchion. Maybe that's what this needs. After checking my spare sliders I can confirm the shelf the seal sits on is 14.5mm from bottom of shelf to circlip recess, so if the seal is only 11mm that's a 3.5mm gap allowing the seal to move up and down. Doesn't seem a good idea to allow it to do that.

I agree Ken that is the seal I have 35 x 48 x 11 - the old seal was binned so I can't compare it now but 100% certain there were was no spacer fitted.

You could try this Ted, remove the circlip, knock the seal back down to the bottom of the shelf and then fit 2 of these, https://www.ebay.co.uk/itm/372421144641?hash=item56b607b041:g:tlsAAOSw0NlbiUol&amdata=enc%3AAQAHAAAA4I%2FsHyGiSMZ9YZ%2Ba020U60gNkob1Cv7cHVttJkwDCZNq9QKHmRV1VTfNemcNLlDEs5MVN5tSUojX7Vy%2FsOdyzcUsYScOvHRO5sVORwuzxrYtYx9lViCmLpfh1n3Dua8TFyaqn7UzkzmSZy5owihdA%2FXvHxi2HqTx3mkm4wkbmySSXQDhjzvRDd2zeBwAG0TmN6benfDFLP35Yw3eRp450COeDomd5Cyce5rOGxoh%2BIT2sD2xIWnAlxjfjDVcstj19GwSr8mZ%2Fq072d9ox0q0DRc5TFm8GdtHKEdJ9sq%2BPv01%7Ctkp%3ABk9SR_S_gMrQYQ

You'd need to enlarge the hole from 32mm to say 37mm to give it a small clearance so it can't touch the stanchion, saying that they are nylon so wouldn't really harm it if it did but better if it didn't. Next time fit the washers under the seal, if you ever do them again that is.

I have messaged them for details of the meaning 13/14.5 in the description.

Ted, the Pyramids seals have just this minute arrived.

The difference in the stated depth is because they state the depth of the body of the seal at 13mm but they also include the depth including the upper lip of the seal, the part that touches the fork stanchion.

They are double lipped but no springs are visible at all, they appear to have sealed the springs inside the seal body, they weigh a lot more than standard seals due to this. I can expose one of the springs if I peel back part of the the rubber seal lip but the upper one is completely enclosed. Small packet of rubber grease included.

They look really good, I'd say go for them.

Just realised I have not updated my 500 project for a while - front forks now re-assembled and back on the bike with new front mudguard etc in place.
Gear shafts  in place in the upper engine casing waiting for a pair of Brown mains from DS - Plastigauged existing Big End shells & all good.
Red assembly lube needs cleaning out - it is remnants from when the old crank was in place last year.

Did something to my lower back last week whilst working in the back garden & pond so presently being sensible until my back pain subsides - I'm going to see if I can hang by my arms from the garage loft hatch to help ease the pressure on my back - it used to work when I was younger.

We have a little outside gym near us, set out in a nice parkland, that has overhead bars plus other parallels etc to do this on. A very simple but useful set that I've used for years. I think it's quite beneficial Ted.

Now fully recovered from my back injury (I hope) so today inspired by Dave's progress I have assembled the crank casing halves.
Hondabond applied thinly & tube from 2022 was still nice and spreadable.
All bolts tightened as per manual. Used existing bolts for under the engine - new SS normal bolts for the top as they are vissible.

Despite new bearings, drive chain & rubbers primary drive shaft fitted  into place without too much force being needed....phew.

Before I fitted the primary drive shaft when I had just fitted the lower casing bolts I packed the primary hub with a folded tea towel to prevent the starter clutch from separating from the drive hub when rotating the cases.

I know the clip you mean - thanks - I will look for it as it was not attached to my bolt storage system with the washer  - cardboard with holes in marking the layout of all the bolts for top & bottom cases.

Just fitted the bearing lock plate - mine had no washer just the 6 mm bolts - neither do I have the oil guide plate (item 3) photo E15 Page 34 ish - I assume that is for early models?

Okay so today my Brother came over to help me lift the crank case unit into the frame.

Engine base unit went in easily, bottom front lower two bolts plus  long bolt at rear slotted into place to keep it stable.

I know the upper rear long mounting bolt has a spacer but it looks as though there should be a much shorter spacer between the clutch side of the engine & the rear frame hanger - just a guess there should be a thick washer/spacer something around the 10-12 mm mark?

The parts book & my Haynes Manual show a right hand distance piece (item 9 p/n50357-323-010) it looks very much bigger so was this for earlier frames/engines?

Just need to know what if anything I am looking for as if it is a 10mm spacer I should find it listed in my parts location spreadsheet. I suspect I might even have bought a SS one from Max that was months ago so it will be in an ultra safe place of new parts - contents not listed?  ::) ::) ::)

Nothing on the upper rear bolt except the spacer fitted on the left hand side between the crankcase and the frame. The hanger goes on the inside of the frame.

50357-323-010 is fitted on the left hand side of the lower bolt, again between the crankcase and the frame. Nothing else Ted, if there was you'd see it on the parts book diagrams.

So do I, I've found the top one, I have the axle ones plus the brake hub special bolt. Plenty of time to slip it in when I find it. As my build progresses I have fewer boxes to search.

I plan to do an audit of my parts boxes over the next few days to reflect what I have recently fitted as well as reduce some of the boxes. Good organisation saves time especially wasted time looking for things that might not exist.

Updated:- Found the SS bottom rear engine spacer. ;D ;D ;D

Bottom bolt Ted, goes between the crankcase and that frame lug sticking off the frame. It's quite thick TBH, about 10-12 thick IIRC. Max does them in stainless.

I'll own up I misread the picture in the parts book  -the rear tube where the stand pivot shaft is looks as though it was part of the spacer!

A little bit of progress today - I've fitted the pistons without drama.
 - no lost circlips.

Next up is fitting the block I'm okay with the pistons just need to work out how the cam chain tensioner fits first. I'm presently cleaning up the two oil restrictors in the ultra sound cleaner. I have the 4 cylinder bottom O- rings & bottom gasket at the ready.

In my head I do not fully understand the placing of the fixed blade the manual should help.
Any tips welcome.

The front, static, blade goes INSIDE the chain with the rib facing forwards.
If you dont you wont get the cam sprocket on.
I find it easier to fit the tensioner mechanism with the barrells not all the way down to make sure the bottom goes into the pocket its supposed to

Second that. Leave the barrels about 1" from the crankcase, fit the tensioner bolt through the barrels, don't fit the nut. As you drop the barrels watch to ensure the tensioner goes into the slot in the lower crankcase. When it does, fit the oring, the washer and the nut. Push in the tensioner blade all the way and then lock the nut off. Don't release it until the cams in place and setup correctly.

Same for the front guide, fit when the barrels are standing slightly proud of the cases. It has an arrow which faces up, also says UP IIRC and as Bryan points out it goes behind then chain so that the chain goes between the guide and the front of the barrels.

Thanks for the pointers both of you:-

So the cam chain adjuster screw is on the rear of the engine,  the fixed blade being fitted so the chain is between it & the front of the block.

For the fixed blade I can see it has the word UP on it with a two pairs of arms  - I can see the side arms that sit in the engine casing recess at the bottom - so it sort of hangs from the slots in the top of the block until it fully engaged at the bottom - sounds fun.

Block fitted today:-

Lower block gasket & O rings & restrictors  in place - the four larger block seals fitted to cylinder block - part lowered block to fit cam chain through tunnel.
Block fitted onto studs lowered down to a small wooden support block on rear edge of chain tunnel  - pistons fed into bores 2 & 3 then 1 & 4 with cam chain through tunnel - cam tensioner & guide fitted into place - adjuster locked back once block fully lower into place.

All feels good - plenty of exercise walking round the bike ramp whilst feeding piston rings into block.

Check the tensioner has located in the slot in the lower crankcase, then check again just to be safe.

Should also have said to check the tensioner itself, after speaking to another member recently it's apparent a number of these tensioners are actually bent like a banana, caused by fitting the tensioner into the lower slot and then trying to fit the bolt through the barrels, doing it this way can bend the lower part of the tensioner as it's only pressed steel with little structural strength. This causes the blade to bend ever so slightly thus putting more pressure onto the chain than it should and if the chains new that means it's harder to get the chain onto the sprocket and the sprocket onto the cam.

I have 6 or 7 tensioners all restored and bagged, one showed signs of not being in the slot, the bottom edge gets chewed by the primary chain, 4 others showed bends in the lower half of the tensioner, when new the tensioner is straight, if yours looks bent it's because it is. Another way it could be bent is in how it's removed, you remove the nut etc and then try and remove the bolt from the barrels, this can do the damage in reverse. Always lift the barrels slightly before removing the tensioner, just to disengage the tensioner from the locating slot.

Thanks Ken,
The long tensioner blade was nice & straight I positioned it vertical with a gap of around an inch at the bottom. Fitted the fixed guide so it was pivoting at the top - I could see the lower section engage in the recess. I knew the rear blade was in position at the bottom as it did not move sideways when block down- after locking the nut in place with the adjuster screw in the fully back position - top part looks nice & vertical.

Getting there Ted. Forks look shiny ! Some of the bolts around the headstock and fork tops look comparatively less so. I have bought a couple of new fork tops from DS and will put an order in with Kay fasteners for some stainless nuts and bolts. Not expensive and I always think stuff around the instruments handlebars  and forks that you see when riding is the most satisfying to restore.

Going backwards today taking my swingarm in for a second go at powder coating….
After all that work on the engine best to keep dog hairs etc well away…. :)

I've also polished some stainless bolts not from Middletons and they look chromed if you do them right.

Clutch unit now assembled and shimmed up behind the new SS circlip.
Now back to more polishing work on the clutch cover/ case just done a number of 30 minute sessions on the buffing wheel in the last couple of days using  coarse then medium soap.

Keeping the deep scuff marks for now just aiming for a nice shiny overall finish when I move to the fine & very fine soap over the weekend - trying to do stuff whilst Wendy is at work during the middle of the day in her new part time summer job.

Starting to get the hang of this polishing lark Ted. Looking really good.

There are some Dremel attachments with a small felt drum on them, already impregnated with buffing compound, they ain't bad for those screw holes etc.. Not cheap but they last a while.

Only thing I will say is I would consider doing those small marks on the top surface between the dipstick and kickstart holes, you will start to regret leaving them after a while I find. Although it means doing a bit more sanding on a polishing surface it's only a small area and it will buff up nicely again afterwards. Just my opinion, feel free to discount it.

Personally I've yet to find a 500 that doesn't have 8 fitted from the factory, my engine number is WAY past what Honda claim to be the cutoff point and that had 8 as standard. The K2 parts book for instance shows them still be fitted and by the time that came out it should have changed over to the 4 shafts only, so why show the 8?

Parts manuals seem all over the place about the number of shafts.
in Aladdin's Cave the Japanese CB500 K0 parts list only shows 4 shafts.
+ the CB500 K0 K1 list dated Jan 30, 1972 also only shows 4 shafts.
+ I have a parts list (downloaded from honda4fun I think) that is supposed to cover K0 K1 K2 as Page 4 pictorially showing both 4 and 8 shafts. 4 shafts to 2006337 and 8 shafts from 2006338. (or maybe this is a mistake and should be the other way round)

None of these had the later 4 pinned shafts fitted to later 550s. SB08 11/08/76 covered this. It seems strange that Honda did not fit this mod for a full five years after 500s were first sold. Or for some reason did it only become apparent on later 550s.

I think people read the parts book wrong, says 4 shafts UP TO 2006337, 8 shafts AFTER that number. Must admit to doing that myself. My 05/71 parts book only shows 4 shafts, no picture or mention of 8 shafts.

When they changed back to 4 shafts again much later in the production run they weren't staked like the 550 ones, the 500K3 were staked as that's using a 550 style rocker box

My cylinder head is having a very light skim to remove a couple of marks that I was not happy with as they were where the four circular metal seals on the head gasket fit around the cylinder bore. Can't collect it from the Engineers until I test negative for Covid (hopefully Friday).

In the meantime as I am feeling a lot brighter I've started to sort out various electrical connections as it is a bit of a mess in several places with the ravages of age making many of the PVC type sleeves hard plus a bit of a mix of connectors from previous work. You can see why I was thinking of replacing the loom but for now making do with some new connector blocks & some tape work fitting new connections where needed.

Not 100% sure but I know the 550 loom routing is different than that Ted. It goes under the lower yoke and is held by a clamp which bolts onto the yoke. Whilst there is no 500 routing diagram to my knowledge I think the 550 routes better. There is also another loom hanger which goes behind the tank mount rubber.

Whilst there is no 500 routing diagram to my knowledge I think the 550 routes better. There is also another loom hanger which goes behind the tank mount rubber.

I have a spare loom guide for a 400 that fits behind the left front tank rubber so plan to use that if it helps, as regards the route at the front column area I have atm routed mine like this photo below I think its Julie's 500. No wires connected up as yet as I'm taking my time to get the various wires in the Headlamp bowl in the best position.

My cunning plan (if it even works) is to work with the battery earth connected normally, the starter motor cable disconnected for now.  I plan to use an inline lamp between the positive battery post and the live end of loom as a sort of safety fuse (suitably insulated joint).   

The lamp I use is an old lamp unit that used to be part of an old car tool kit from the 1950's that you clipped to the battery before the days of illuminated engine bays. I can put a variety of bulbs in the lamp fitting, atm I have a 12 V 5W bulb in the lamp.  As I connect various wires if I happen to accidentally contact a live wire to earth then it will illuminate the bulb/or blow it instead of overheating the main wiring loom. I will use my AVO meter & additional Hella test lamp where connections are uncertain.

If its anything like my 400 was most wires are a straight forward colour match so the more that are plugged in the loom the fewer unknown wires that remain. Some colours such as light blue/light grey/ light green are not easy to decide what they are. I'm not colour blind as such but faded colours can be tricky to identify as your eye sight ages.

Ted, I had the same problem as you identifying wire colours that were faded and similar. Then I fitted LED light battens to the garage instead of the original light bulbs and using an inspection lamp in some areas. What a difference the better light made! I could differentiate the wire colours easily. I just didn't realise before how poor my garage lighting was. Not an expensive upgrade either.

Nice tip about  wiring in a test lamp Ted, I ll try that.

I started connecting the Indicators today I found that instead of them flashing they just lit up the test bulb even when I upped the bulb from 5W to 10W so my idea has not really worked out.
Decided instead to fit a temporary in-line blade fuse where the test lamp was fitted as a precaution until the loom connections are all sorted.

First good outcome was the left side indicators work just fine including the additional left side LED unit in my tail lamp unit.
Next will be sorting out the idiot light repeater connection.

Did a tad more on the wiring front all indicators now working including panel light, neutral light, oil light & brake lights. Ignition circuit part done.

I'm scratching my head over the starter button as the yellow/Red wire is live but the button contact wire is black?

Next job is side lights & headlamp wiring.

I had a good couple of hours on the wiring connections today, sorted the side lights, headlamp & dip beam all now working as they should.

Items not currently working as they should are the pass switch & starter button.  No Horn fitted atm  - that should be straight forwards.

ATM the connections are anyhow in terms of orientation/routes with some temporary bridges, once everything works I will tidy up the Spaghetti appearance so I can fit my slim LED headlight unit.

Only blew my inline fuse once yesterday & one today (5 amp) so pleased I went to the trouble to fit one as a temporary measure on the live battery terminal.

PS: Not checked the kill switch as yet!

The problem Ted is your trying to marry up 550 switchgear with a 500 loom and that's not going to be a doddle.

First of all the yellow/red is supposed to be earthed by the starter button on the 500, on the 550 it's a different arrangement as the 550 has a clutch switch and sensor so the starter solenoid won't work if the bikes not in neutral or the clutch isn't pulled in. You haven't got the wiring for that. On the 550 the yellow/red connects to a green/red when the button is pressed.

You also seem to have a yellow/black connected to 2 blacks for some reason, yet there is a female yellow/black up near the top connected to something else, what's that about.

What does the black/blue wire connect to in the switchgear? I have a sneaky idea that's the power source for the headlight flasher and horn, try testing to see if there is continuity between the blue and the black/blue when the pass switch is operated and also light green to black/blue when the horn is pressed If so that wire goes to the black connectors in the loom..

I have some connections that have no colour logic but work - it's certainly not completely finished as yet.
I have a black live double connector on the loom end connected to  a single Black/Yellow trace wire from the right side light switch - this made the sidelights & instrument lights work as they should when ignition is on.
I have a temporary bridge between the left switch - male Black/Yellow trace connected to right switch - Black/Red trace, This made the headlamp position on the right handlebar  switch work, main & dip work on the left handlebar switch.
I have an unused black male wire  on the right side handlebar switch - this is probably related to the kill switch?

I need to check the solenoid connections again, if it's just a matter of earthing the starter button I have a spare black wire on the right side switch that I can connect to earth but at the moment pretty sure that would blow the fuse as the Yellow/Red trace is live & reads a good 12 volts.
As you have mentioned there is a "Spare" Black/Blue trace wire on the left side switch as yet unused.


My switch gear came from Germany listed as follows - CB 400 500 K2 550 750K3-K6 Four

Short update Bryan - I've connected the spare black from the right side switch to earth & solenoid now clicks - starter motor lead not connected at the moment. I've wrapped the black with earth coloured tape.

You would be better connecting the black to black power, the yelloe/red to yellow/red and at the solenoid the small wire that DOES NOT connect to yellow red is connected to an earth(green).
That keeps everything in the shell colour to colour for next time and only the solenoid, which is rarely looked at, different to standard

At the moment I am painting my cylinder head prior to re-fitting the valves etc.

Whilst waiting for paint to dry I did a tad more on my headlamp & switch connection issues with having 550 switches on my 500 loom.

With the exception of the Pass switch function I have everything working now so getting closer!
Trouble is I have no spare wires so it's closer but not quite right - I might end up fitting a relay for the headlamp flash function.

Oh oh when I take the key out in the far right Park position rear side lamp & front beam on! I'll leave it until I've fitted the cylinder head.

Bryan did say I might have some issues with these switches..lol

These are my switches  Bryan links below, in one of the photos most of the wires look to be all black but they have a trace colour on them that does not show in photos.

Both the starter button & the horn have a separate earth wire connection so they were pretty straight forward to connect up. I'm distracted at the moment as I want to get the cylinder head & camshaft all buttoned up before the cold weather sets in so wiring work will be at a standstill for a couple of weeks - any pointers welcome though.

Not helped by having another minor operation tomorrow afternoon to remove a BCC on my shoulder - top marks to my Dermatologist for spotting it & my two Melanomas that he has removed in the last couple of years. They blame sun damage but aside from one holiday  back in 1967 I have never sunbathed or worn a sleeveless T shirt as I am and never was a beach Adonis or sun worshiper.

OK ted, i know what you have done but not what wire colours you have done it with.
The wire from the H on rh switch needs to go to the input of the dip switch on lh side
The P from rh switch needs to go to brown and/or brown white in headlamp
Black from rh switch(should be two of them) go to black power
Black from lh switch goes to black power(may be two of those as well)
Pass switch may have a seperate wire to shell or may connect inside to dip switch
Horn will need to have ground wire at horn as switch will power it.

You have already found starter has two wires and i explained how to keep shell standard instead of way you have it.

Hope that helps mate but long distance electrics aint easy, remember electrikery dont smell(unless you let the smoke out) dont taste much but by christ it bites

Plan B

Until I have the sutures removed from my right shoulder shoulder I am leaving the cylinder head assembly & fitting for a couple of weeks so instead I'm biting & bobbing with the wiring again.
 I have following Bryan's wiring tips with some success. (Early Days)

I have undone the switch halves from the handlebars  to try to work out what goes where inside and made quite a bit of headway I think.  As yet the pass switch is not functioning but everything else seems to now work.

I no longer have the front beam coming on with the switch in the far right position - parking light I think - trouble is just the rear lamp illuminates not the front side light. Is this how these old bikes were wired up?

Post by: Oddjob on September 06, 2023, 07:35:24 PM
Seem to recall the front side light also lit up on park position Ted.

There should be 3 wires going to the pass switch, light green, dark blue and black. If you have the light green and dark blue whatever the other wire is goes to black on the loom. It should work then.
Title: Re: Teds new project a CB500 K1 mostly version 0.5 circa 1972.
Post by: McCabe-Thiele (Ted) on September 06, 2023, 09:12:23 PM
I think you are right the front sidelight should illuminate as well.

I'll look at the Pass switch again as I have some spare wires atm.


Update: 
I had a bit of a Eureka moment when I went to bed last night, this morning I changed the way the Horn function operates (as hinted by Bryan) so there is an earth wire at the horn end instead of the button earthing it. The black wire now supplies power to the horn instead of being an earth connection (much like the starter button). When I tried it this moring the Pass switch now works as does the Horn.  I am now left with just one unused wire from the right handlebar switch - Black/blue trace. The original right side switch had 6 wires the new switch has 7 wires so not an issue to have a spare wire. I have a couple of wires that seem to contradict the matching colours I would expect - I will take a look at those & see if it changes anything.

Only very minor  issue left is the front side light does not come on in the park position only the rear one - if I do not find a fix for that I can live with it as I have never used parking lights on a bike anway. Seems strange really as the front & rear side light are on the same circuit in the P light switch position. I would have thought that if the Park light position on the main ignition switch sends power to the rear lamp that it would also power the front sidelight - clearly it does not.

The sidelight issue had me scratching my head too. If the side light comes on when headlamp switch is on, but not when ignition switch is in park, you probably have wrong wire to front sidelamp. It should be a brown wire, NOT brown/white (these supply tach and speedo). I did not realise that the power for sidelight/rear lamp takes a strange path, from r/h handlebar via brown/white wire back to ignition switch terminal TL1 then to TL2 which is the brown wire, then to pilot/rearlamp. when ignition switch is in park position power goes directly to TL2 for parking. If you look on the wiring diagram i sent you it makes sense. The odd blue/brown wire you have would have gone to fusebox on 400/550 so not needed on your 500.

I think you have identified my issue Mick I have the front sidelight in the same connector as the instrument lamps.
The old side light bulb holder & short harness on my 500 looks suspiciously like an old instrument light harness.
It has a moulded bulb holder at the end - the wires are green (earth) & brown/white trace.
I have that connected with the other brown/white wires in the harness with the instrument lamps.
The plain brown wire in the harness has a feed from the right handlebar P side of the switch it is black/yellow trace on my switch iirc.

I will need to put an extra connector on this to siamese the side light into the feed from the P side of the switch. I have just done my first fit of the LED headlamp unit into the bowl spreading the wires evenly so the light unit fits okay. There is plenty of space as my LED head lamp unit is quite shallow.

I will try that in the morning and report back.

TBH if Ted had done some close up shots and concentrated on the wires from the switches we could have worked it out much easier. You need close pics to work out the traces on the wires, you can't tell what's what from a distance.

Had I needed the bike to go to work then it would have been a major issue - as it was just spending half an hour attaching a few wires seeing the result, bimbling about looking at the wiring diagram, blowing a couple of in-line safety fuses, swapping a few wires, testing, reading tips here, it was all sorted in 10 earth  days during that time I had Covid again & a minor operation so in reality its been just a few hours of real work. Anyway today I checked everything is wired up & all is well.

I'm under close survaillance by Wendy atm so the cylinder head & camshaft fitting will have to wait for another 6 days until I have the 10 or so sutures removed. It will be nice to have the engine buttoned up for the winter if everything goes to plan.

Over the weekend I fitted the cylinder head using the 12 flat washers & a few new head nuts kindly supplied by Ken all torqued up without event. I decided to leave the fitting of the camshaft until today so this morning revising my plan from  the  workshop manual & some tips here on old posts I tried to fit the chain.

I failed completely to get the chain to fit on the sprocket  after 40 odd minutes of sweat getting hot & botherd so I gave up. I knew the old chain was a snug fit so my new H/D chain would be difficult. I had  pub lunch with my little brother. (At lunch I was going through areas in my head that could be a cause - chain too short, tensioners not fitted correctly, self doubt starting to depress me).

At about 6.00pm this evening I decided I would have one last go for today so I did something slightly different that I suspect is of significance as the chain/spocket are now in place with the valve timing checked as per the manual.

Sorry if this is obvious to the experienced members this is what I did. Cam chain had a cable tie through it looped over the top of the frame, likewise the sprocket had a cable tie through one of the bolt holes. Crank timing marks was at TDC 1/4 position.

I then started  to  feed the camshaft from the right side of the engine but put the chain over the camshaft first then started to thread the camshaft throught the apatures in the sprocket until the sprocket was in place but not  fully seated on the boss (cable ties removed when no danger of chain or sprocket falling into the engine). doing it from the right side - this gives you some slack - I made sure that the chain was in the right position for the two bolt holes to line up with the camshaft end marks in the right position. Checked that crank still at TDC. It is quite easy to rotate the sprocket with no chain yet in place checking the camshaft timing mark is where it should be. So visually if the chain was on the sprocket the valve timing would be correct if you get my drift.

For some reason with the chain to the right side of the boss this enables the chain to be fed onto the sprocket by hand. All that remained was to give the sprocket a little bit of leverage from the left side through one of the appertures that then lifted the sprocket onto the raised boss - bolted in place making sure a cloth covered any chance of dropping a bolt down the chain tunnel. It went on a treat - my earlier failure was starting with the chain on the left side of the sporcket so somehow doing it from the right side worked.

So let me get my head around what you've said Ted.

You've essentially threaded the camshaft with the cam sprocket hanging loose on it through the chain, with the engine at cylinder 1 TDC, T mark 1-4 lined up with notch. You've then turned the camshaft so the slot is flush with the head surface, then sort of aligned the cam sprocket so that if you were to fit it now it the bolt holes would line up. Then mounted the chain onto the sprocket and then levered it onto the cam, bolt holes lined up, slot was still aligned and crank hadn't shifted.

If that's so then that's exactly how you should do it. I seem to think people are trying to fit the chain onto the sprocket with the sprocket mounted on the cam and that's not possible, not unless the chain really stretched that is.

It's fit cam through chain, mount chain onto sprocket and then fit sprocket onto cam, IF the holes don't line up then work out how many links you need to move so that they would, dismount sprocket, move chain and try again. Most times you're a link out.

Post by: McCabe-Thiele (Ted) on September 11, 2023, 09:20:03 PM
Essentially yes Ken that's what I did. When I tried it with the chain   to the left of the sprocket first not only was it almost impossible to get the chain past the top of the rear tensioner but I just could not get the chain on the gear teeth even when it was not on the boss.

The manual just mentions passing the camshaft from the right side through the chain & sprocket without specifying the order.
I think the order is important as it affects the space you work in and the angles.

I've read my post about fitting the cam chain - it reads oddly complicated.
Put more simply the camshaft is fed from the right side loop the chain through the camshaft first, then feed the lobes through the sprocket. Doing it this way results in the chain being on the right side of the sprocket & boss on the camshaft.

Wouldn't it be easier to fit the sprocket past the lobes whilst it's off the engine Ted, leave it hanging next to where it fits and then thread it thorough the chain?

Post by: Sesman on September 13, 2023, 08:11:18 AM
As Ted described, the trick is the initial set up as pictured. The trick is to engage the chain on the sprocket off the cam, rotate anti-clockwise to locate the first bolt then turn clockwise to engage the second bolt. Check the alignment. If it’s incorrect reset the process, but compensating for selection of the correct cam tooth. I know you know that by the way, Ken.

It's difficult to explain but if you do it  that way I found  the left  end of the cam grounds on the head well before it can reach the end bearing. You need to end up with the chain on the right side of the sprocket not the left. Phil's photo says it all.

On a used chain it might work if the chain is on the left side.

It is indeed K2-K6 plus my negative inner self is telling me I must have the guides in wrong whilst my "you can do it" side of my brain says no you did them right and tries to calmly look at all the angles.

Yeah, I was pulling your leg as well. It's a bit like fitting the primary chain when it's new, sometimes it needs a helping hand to get it to fit. Whilst a part worn one just falls on.

Oddly, I've never had a problem removing a camchain, I tend to remove the 2 bolts and knock the sprocket off the cam, loads of slack then.

Cam cover now finally in place so that is the engine unit buttoned up for winter. Currently sorting out the carburetors that should not need too much work doing to them as they were restored a couple of years or so ago by Gerben. Standing has taken its toll with rusty carb bowl screws and what appears to be loose O rings that I will replace.

Hit a small snag when assembling my cleaned carbs with new O rings using NJ's excellent kit.

The first three carbs went together a treat but number four carb has one stripped bowl thread - not too bad just one out of 16 screws - almost half the screws were rusted so probably due to removing a screw that was rusted.

IIRC from DomP post a M4 Helicoil will sort it - any links to a suitable repair kit welcome - I am a Helicoil virgin regarding DIY kits so any advice is welcome. I assume kits come with a drill bit - can this be done hand held as I do not have  a pillar drill?

I will look on U tube for an idiots guide.

Don’t drill unless you really need to. In alloy the metal is so soft you can normally just use the tap to enlarge the hole. I’ve done loads of M4 repairs in carbs and they’ve all lasted. Buy a kit off eBay

The insert is normally a few threads too long so cut a couple of threads off.

Petrol pipe & vent tubing  arrived today so now have the carbs ready for fitting to the mainiolds - I will attach them to the bike and test for fuel bowl valve leaks.
I know they are only fuel vents but think I will slip some new short pipes in between the carb bank as the left one is a tad manky.
Bench synch done.

Adjuster screws seem high to me Ted, you may find hanging idle with them that high. Try winding them all right down and then bench sync with a 2mm drill instead of a 3mm one, wind the idle adjusting thumb screw right out so it's not touching the lifter arm.

Also open the choke and check all the flaps are level when the chokes fully open.

Pic from the front as well please, I'd like to see how that ceramic chrome effect bracket looks when all the carbs are fitted.

I thought they looked high as well - I used a 3/32" drill bit.

Post by: McCabe-Thiele (Ted) on October 18, 2023, 08:33:35 PM
My idle adjuster thumb screw was not fully wound out - about a quater to a third  turn off the stop - does that affect the screw height?

I did this intentionally so if my idle ended up too high it left me with a bit to play with as I could lower the slider height evenly. Presumably me doing that has lifted the other part of the linkage so more thread shows.

Would I be better off unscrewing the thumb screw off the stop completely then setting the sliders at say the thickness of a pop rivett shaft?
Title: Re: Teds new project a CB500 K1 mostly version 0.5 circa 1972.
Post by: Oddjob on October 18, 2023, 09:58:35 PM
The thumb screw needs to be fully wound out so it's not touching. When it does start to touch it lifts ALL the lifter arms, the screw doesn't move, that's there to lift each arm separately so the slide are the same level. Unless the thumb screw is fully wound out you can't do the bench sync as it will be miles out.

Try winding the screws right out. Look down the front of the slides, they should be fully bottomed, now do each screw in turn until you see the slide just start to lift, stop there. Do each screw so the slide is just starting to lift. Then screw in the thumb screw and you should see them all lift at the same time, when they do check they all look the same. This way the slides will be fully shut if the thumb screw is wound back out again in the event the tickover is too high or it starts to fast idle etc.

I like that idea Ken - if all  the sliders are just on the point of opening then a hanging throttle shoud be banished.
I guess also pressing down on the brass cap will give little movement from the above setting.

No fuse holder Ted?

Missing the black plastic cover off the kickstart lever. Keeps the crap out of the knuckle joint. Seem to recall someone making them and selling them on Ebay. https://www.ebay.co.uk/itm/143595737695?hash=item216ef9125f:g:ZOQAAOSw3axerz5U&amdata=enc%3AAQAIAAAAwLuy3C3OQhU4zlKnwPJLWjEOmwDTqoW1C5kHiSHqlK85R9s%2F5Q6TMEOfXlqcNbqJJsd7ra2JWQx4GyVXOhS5%2Bk9W3%2FFJOy419uId7Ul%2BEjAusA%2FC%2Fm78u6CDjZqKs0nfY954LwyCiRg%2FQPaQHRBhuXuzTdscUV%2F2BO%2Bz7AgJmZutQsZX0n%2Fsx8aMgGi89k7gTVzQpkPuST7waq%2BRreNqsCqPFaEnmpbNpI%2B6a5d82EqUPIJ%2BYpjj09AlH8SdA2UUcg%3D%3D%7Ctkp%3ABk9SR9Dw4ZLsYg

Be careful using domed nuts on the intake manifolds, I've found that unless they are really deep ones there is a chance the nut bottoms out on the bolt, you think it's tightened up so you stop, then you find it isn't tight and it's allowing air to be pulled in past the oring.

Something like these are better. I use those on the exhaust studs as well, keeps the thread from rusting and you struggling to remove them afterwards.

Not supposed to be a grommet on the tooltray Ted although I suspect you know that. It doesn't rattle in use so it's not really needed TBH.

The HT cap shown is wrong for that location, that's for 2 & 3 cylinders, the outer ones use a long right angled one.

Coming on, starting to look the part. I suspect the breather cover is off a 550 BTW, the vent pipe outlet comes out on the other side to the 500 one IIRC.

Pay attention to the way the bolt fits for the rear brake lever adjusting bolt, can't remember offhand which way it fits, bolt head down or up but it's one you can't change over without removing stuff so it's better to get it right before fitting the brake lever. The workshop manual shows it bolt head up but there is a pic in there I'm convinced shows it bolt head down. I'd fit it bolt head up myself.

Thanks for the feedback Ken it is very helpful.

I expected some comments on my excessive use of copper washers on the cam cover.
My temporary fuse holder was on the live side - now removed - what fuse holder do you mean?
The domed manifold nuts were fitted by Bryan and are a tall domed type.
Plug caps - my bad just wanted the overlong wires out of the way.
I fitted the grommet to hold down the front of the tray as it tends to stand up on the left side with no seat in place.
I'll see if one of my rubber blanking grommets fits the kick start - I might even have one from a 400 lever I had.

Sorry in advance Ash for the SS Hex Head side cover bolts - fitted by PO.

I have fitted the new throttle cables this afternoon - throttle return is okay but feels a little bit three penny bit on the return when you let go of the throttle completely. Action feels like a sort of spiral binding.
Should I have lubricated the new cables first?

My cable routing might be questionable as they pass through the forks.

Nice reduced amount of throttle rotation needed for full throttle as a result of fitting the throttle tube that Ken told me about. (CB1300)

You can use silicon oil to lube the cable inners Ted, only silicon oil though. Check to see if they are aftermarket ones, the genuine have a teflon sleeve over the braided inner cable, aftermarket tend not to. Routing is VITAL on those and the clutch able. Check 550 appendum as there is a routing guide in that..

Fuse holder goes in the little slot in the tooltray, it holds 3 spare fuses which is vital for the 500 as it only has a single fuse and if it blows everything dies, and I mean everything. You're pushing it home if the fuse blows and you don't have a replacement handy. Very hard to find, even I have only one.

One of these.

https://www.cmsnl.com/honda-cb500k1-four-england_model14660/case-fuse_38205323000/

Quite rare, Graham had some made a few years ago, no idea where he got them done. Maybe 3D printed?

The tooltray must be bent if it sits up at the front, it shouldn't. Maybe a little heat and some persuasion is needed.

Good progress Ted. Why did you use copper rather than ss washers on the valve cover ? I would love to see a photo of those bolts you used next to the tappet covers on the front. Your engine paint looks great. I’m  way behind now - haven’t rebuilt my carbs yet. Looking forward to your first start up. 👍

Photo of bolt Dave only fitted them to the two outer front bolt holes where the issues were with fitting the cam caps due to cost.

Cam caps in photo have not been cleaned up as I have some standard replacements - the chromed ones I bought from DS are too bling as well as my concern over the threads.

Not sure what specifically did it but I spent some time on the throttle cable adjustments for opening & closing plus altered the angle of the point where the cable unions  connect to the throttle body so that the curves on the cables followed the line better. I did look in Ash's Dropbox but could not find anything that helped me. (probably looked in the wrong places)

ATM the cable routes go from the the throttle, loop down between the forks then follow the frame above the round tank mount (can easily be moved to below the mount above the coils). Photos to follow as I'm going out for lunch & my phone connection is on my PC not the laptop I'm using.

Ted I had mine below the tank mounts on the 550 but they were having a tendency to hook around the lower corner of the fuel tank when manouvering. Definately I would say above the tank mounts can’t drop from there.

So over the fork top on the top yoke, through the gap in the speedo/tacho bracket, round to the left of the headstock, under/over the tank mount rubber (which is odd as one image shows it above and one below, see which looks right, I suspect below as it would bend the cables less) through the gap in the frame where the coils sit and onto the carb bracket.

Thanks for the pics Ken, I saw something similar on the PDI pics for the 500. (USA bars I suspect as the throttle cables are above the clocks and feed down through that slot/hole in the bracket)

I tried to route my throttle cables through the hole in the speedo bracket as per the photo.  The cables would somehow have to get past the rev counter with not much of a gap, swooping up from the throttle grip below the bars through a tight gap near the master cylinder pipe then tight down thought the instrument bracket. They were routed better above the master cylinder but ended up part over  the rev counter.

Hence why am now as per these photos.

One problem at a time Ken I have not fitted the ramp yet but the hole in my switch gear is threaded so will look at that eventually.

I have very loosly tried my clutch cable route - from the bar lever, drops down the slot/apperture in the instrument bracket out on the RHS then through the coil frame hole to the left side  down through the gap between carbs 1 & 2  to the forwards facing hole in the left side housing.

The route looks good except there seems to be excess loops of cable near the tank area - I did wonder if there is a shorter cable for the UK 500 & mine is an aftermarket one. The cable is in good condition - even the rubber bellows at the engine end  looks like new.

I'd leave the top routing alone but route the cables around the other side of the headstock and through the coil opening Ted. See how that feels. The tighter the bends the worse the throttle feels.

Presumably Johnny both your throttle cables were not routed between the forks but to the right side of the frame?

I think that what Ken is suggesting. Do you have any tips regarding the clutch cable route?

At the moment though not connected at the engine end, mine goes from the handlebar lever down the hole in the instrument bracket, crossing to the right side of the frame then crossing to the left side of the frame through the gap at the rear above the coils. Finally dropping down between intakes 1 & 2 so the cable reaches the hole on the left side engine cover.

Do you know the correct length of a UK clutch cable Bryan as I suspect mine is for US bars?

The only way I can find to route mine without loads of 'spare cable' is by routing it not through the hole in the instrument bracket but as it was when I originally rode the bike - the cable passes over the speedo going down to the right side of the frame between the forks. This route does mean the clutch cable passes high over the speedo clock. See below photo as it was.

I have measured the clutch outer cable from ferrule tip to ferrule tip (excluding the adjusters)  it is 4ft 1/16" so that's a nominal 4 ft - with my cable routed in what looks like the best route (#).

That looks like an excess of six to seven and a half inches of outer cable,

# My route is currentky from the clutch lever down through slot in the instrument bracket coming out on the right side of the frame routing above the tank mount then passing through the far end of the coil gap in the frame down between carbs 1 & 2 and into the left side cover.

Interesting read Phillip,   some books & owners seem to show/say throttle cable runs down the left side of the frame others the right side.
I am now happy with my throttle cables running down the right side - they no longer stick - it seems the cable curve/run makes for a smooth operation - even if it's not original. I can't test effect of steering as I have no wheels in place atm.

All the things I have read appear to agree that the clutch cable starts on the right side then crosses over at the coils to the left - this looks good to me.
If I route my clutch cable through the instrument bracket I have loads of spare cable looping.
Even if I route it as it was not throught the instruments but between the right side of the forks there is an excess of cable loop.
The clincher will be when I know what the correct clutch cable outer length is excluding the adjuster for a UK 500.

If my cable is correct at 4ft then the route certainly can't be through the instrument bracket - I suspect that is for the higher US bars.

A genuine UK clutch cable is 107cm from ferrule to ferrule, or 42" if you prefer.

I don't think it routes through the coil opening Ted, I suspect you are correct in saying through the clock bracket down the right side of the frame but I think it crosses to the left just where the throttle cables join the carbs, just before there where the frame starts to flatten out. It then goes through the carbs between 1 & 2 and into the sprocket cover.

I've been looking at pics in the workshop manual Ted, figure 245 shows cable routing for the 500, shows both the clutch AND the throttle cables passing through the speedo bracket, throttle cables then go to the LEFT of the headstock and pass through the coil opening, figure 272 shows them there along with what looks to be the clutch doing the same thing but in reverse. The throttle cables appear to be above the tank mount but I would have thought below before seeing that pic, however they could have moved before the pic was taken and not spotted, I seem to recall putting the tank on and making sure they went under the rubber.

Figure 299 shows the clutch cable passing through 1 & 2 inlet manifold bracket, as does fig 86 and fig 56. In fig 310 you can clearly see both throttle cables to the LEFT of the headstock

Post by: McCabe-Thiele (Ted) on October 26, 2023, 04:56:37 PM
Hi Ken I have seen that throttle cable route through the instrument bracket to the left side of the frame - even worse imho as it's a tight turn up from the throttle grip down into the instruments then back throught the coils to the carb connection on the right side of the frame.
The carb shaft mechanism sits to the riight of centre so atm I prefer my route even if its wrong.

Thanks for the info on the clutch cable being 42" mine is aftermarket - I will see what the clutch cable looks like if not routed through the coil hole.  Most of the manual photos seem to show it going through the coil hole area - that's how mine was routed but not through the instrument bracket.

Advantage of the clutch cable going through the coil hole is it drops at a nice non binding looking angle between the carbs to the left housing.

Oh what fun. ;D ;D ;D

There's something wrong Ted IF the throttle cables are having tight turns when routed correctly. They should exit the right hand switchgear pointing almost straight along the bars, not pointing forward so much. This then points them toward the hole in the speedo bracket. Are they like that?

Exactly that is why I think the manual routes are wrong for the Uk bars as the throttle grip is not above clocks tops but almost level with them. On the US bars they would drop down nicely between the clocks.

On my bike when the throttle cables exit the bars the fixed right angle part of the cable ends means they are pointing not dead horizontaly but very slightly downwards  exiting approximately  3" below the centre line of the switch clamps. The instrument bracket is about an inch and a half below the centre line of the bars but is also angled. The path between the instrument bracket hole and the throttle grip body is not a straight line as the rev counter is in the way.

For the cables to then go upwards they have somehow get past the front of the rev counter as there is no space at the rear of the rev counter due to the brake hose etc. This route is not viable for me - not to mention crossing through the coil gap as well.

You can see there are no tight bends with my present routing plus it should not cause issues when turning left or right as there is just the one gentle swoop/curve of cable.

My bars are not genuine Honda so no dots to align - I have the location holes for the switches & cables so the bar position is basically what looks level & right with the levers etc.

I'm happy with my throttle action even if it's contrary to the manual I need to fit the clutch cable route so it works properly as it did before even if it means the cable loop near the clocks.

Surely that would depend on where you measured them from? I know mine is a genuine UK one from around 1979, back then I doubt any parts depts had any USA stock as imports were almost non existent back then. There is quite a large mark on the sheathing of the cable, right through to the inner braided steel outer, I'd imagine that roughly complies with where yours passes around the tank mount. Next time I fit the cable I intend to split some fuel line and position it so the cable gets some protection.

It might not fit (my bars are not genuine) on the routing I want so decided a DS one (22870-323-621) was a bit pricey for a trial at £54.29 plus postage. At just under £12 it's cheap enough to try plus the seller took the trouble to measure it up for me.

Interestingly my old cable still has the part number on the outer sheath it is 22870-392-000 not sure what model that was for originally. Not sure what -392- part refers to - google says a CB750 A

Replacement clutch cable arrived this morning - fitted at lever end routed throught the instrument bracket gap over to the right side of the frame - loops past the bottom of the coils dropping just right down between the carbs 1 & 2.
The cable is around 8" shorter now fitted at the bottom end.

New cable has the extra outer protective sheath plus the bottom ajustment shroed - presumable that is to enhance cable protection when it passes through the frame or it could be for between the carb banks.

Good to be rid of the 8" of spare cable!

All the genuine clutch cables should have the extra outer sleeving that starts nearer the bars end. The black rubber block (grey on early cables) just slides down as far as it goes at the engine end.
All my measurements were outer cable only, including engine end adjuster.

They were spot on thanks I am happy now with the correct length clutch cable,  the routing is I believe now correct - the clutch action at the lever seems to be fine though clearly can't be sure until its a runner but the lever action feels spot on with adjustment available in either direction if needed. 👍👍😁

Now that the clutch route is correct it's nagging me to change the throttle cable routing - I definitely can't go down 
via the instrument bracket but could do much closer to the correct route - from the bars down through the front forks to the left side of the frame, crossing over to the right side at the coil gap to the carbs.

With my luck the currently smooth throttle action might be lost.

Before the temperature falls any further decided to check the engine for oil pumping, plugs removed, on the third three second burst the oil light flickered before going out. Took a peek at the rockers there was oil on top of the valve springs.

Lastly checked the kick start worked - that's pretty much me done on the 500 until I fit the wheels & an exhaust system in the new year.

Ted, I'm nearly at the point of getting my 550 back I'm the frame so thinking along the same lines as you regarding the cold and engine internals as I'm going to have to save up a bit before the exhaust system goes on.  Are you going to leave your engine topped up with oil and turn it over now and again until spring before you run it in?

Before the temperature falls any further decided to check the engine for oil pumping, plugs removed, on the third three second burst the oil light flickered before going out. Took a peek at the rockers there was oil on top of the valve springs.

Lastly checked the kick start worked - that's pretty much me done on the 500 until I fit the wheels & an exhaust system in the new year.
It’s reassuring to see oil pressure is there after all that work inside the engine isn’t it? I’m fitting a delkevichb4 into 1 on mine - that’s what I had in the 70’s and it frees me up not to get over worried about trying to recreate an oem original bike - just one that looks good and works well and has my labour invested in it.

I kept a bike indoors once for the winter, it was when I was actually rebuilding the 500 I'm doing again now. It had never been run, in the spring when I was getting ready to get it ready for the road I checked the oil only to find it was full of water, clearly condensation was running down the insides of the cases and collecting in the sump, me kicking the bike over ever week or so had just mixed it all up like mayonnaise. I ended up taking the engine completely apart again just to clean it out of all the cracks and crevices, luckily I was still in the trade then so the gaskets were cheap. No damage or rust in the engine but bloody annoying even so.

Keep that in mind.

This is the silencer I got with the bike. It’s new as the 4 into 4 fitted when imported was unsalvageable. I thought about spending 1200 quid with DS but reflected that this is a nostalgia project for me and the  bike I rode to Italy and back in 1979 had a similar 4 into 1. It’s liberating if your bike is for personal use not to be nailed to the cross of originality.

Tip: You need to keep the central heating on overnight to avoid the condensation Ken.

I'm toying with the idea of one of those wardrobe tube type heaters under my bike ramp - trouble is it would need a floor to ceiling curtain round it as well.  ;D ;D ;D

It was in a small shed which is actually part of the house, however the door to it opened onto a small atrium, covered over but on the other side was another small shed which was built to be what we Northerners call the Coal Hole, so even though the house had central heating this part did not. In fact it didn't even have any plugs in, just a single light, the coal hole didn't even have that. It's all gone now, I extended the kitchen to include the coal hole and the atrium, the shed which was built as a sort of storage room by the builders is now the Utility Room, has the washer and the dryer in there and another sink for soaking clothes etc along with a very large upright freezer and a very large upright fridge along with a lot of extra cupboards. The door now opens into the enlarged kitchen and the opening in the side of the house now has a door in it which opens into my bike garage.

As Wendy is away this week I took my wheel hubs to CWC for them to rebuild to my specification - looks like it will be the end of January or early February before they are done.

I've been trying to paint the chain guard finding the ambient air temperature not condusive to rattle can painting in my unheated  garage -  bike work has now effectively ground to a halt until spring.

My seat has had a new cover but the metal base has surface corrosion on the edges where the clips have scratched the paint.
The seat foam does not look great where the holes are - you can see the foam degredation. Never been one for upholstery - my local guy Stan Chilton died a few years ago he fitted the new roof on our R129 a decade or more ago - he would have done a quality job.

I will post some pics of the seat for advice as what to do about it - if anything - as a teenager I would have just brush painted it with Hammerite but somehow that does not cut it for me today.

Ted I had my K3 seat stripped and redone with new foam, cover and base blasted and powder coated. When the seat was stripped it was found to have a split on both sides of the seat pan due to flexing over the years. That alone for me made it worthwhile having it professionally done. The problem with the deteriorating foam is it can end up getting into the intake. Cant block the holes either they are there for a purpose.

I need to find a local firm if I go for new seat foam & base powder coating that might be something for next winter - I hope to have the bike as a runner again by early May 2024.
The seat looks better from one side than the other though to a casual observer its good for a 50 year old bike - just a bit lumpy on one side for want of a better description.
The clips are LIGHTLY rusted but might clean up with a wire brush & some painting in the short term.

Decided to keep the seat as is due to costs until the seat has to be restored fully.
I rubbed off the rust with W & D then zinc primer left it to dry for a week.
Smooth Hammerite paint - just need to touch in a few more bits to stop it getting worse on the underneath.
Photo makes it look like I painted it with a yard brush with streak of brown - I must try a soft focus lens next time - looks better in the flesh than in the photo.

I've just checked my build log, I dropped the bare wheel hubs off on the 30th November 2023. They said they should be done by mid February 2024 or thereabouts.

I chased them up after the 15th February by e-mail they replied that they were waiting for the Rims to come back from the Anodisers. Time scale wise it was about the same time for my 400.

On the plus side it's removed the temptation to get frozen in my garage over the winter plus time to save up too.

I collected the wheels from CWC - happy with the wheels and the left side rear sprocket carrier hub part all powder coated in a sort of chrome / alloy finish similar to my 400.

I will post some photos up later - my only disappointment was the rear brake hub that was a less than a perfect finish having a few spots & small pimples. I had what I thought was a quite defensive discussion with one of the Guys who basically said on 50 year old alloy it was the best they could do due to an issue called "Gassing" when powder coating.

In reality when the exhausts are fitted it might not be too visible - it just spoilt an otherwise good outcome.

At least you have got them back Ted and can now continue the build.  I had my hubs painted with Ford Silver Fox. The wheel builder took less than 24 hours to lace them up. Just waiting for my tyres now from Demon Tweaks, I bought a pair of Pirelli City Demons, they are on special offer at the moment with a 45% discount. If I could get into my bank app I would tell you how much I paid but the app is on my waterlogged phone! I know the two tyres, two pirelli inner tubes and two rim tapes cost less than £200 so maybe worth a look if you haven't bought the tyres yet.

My hubs are okay - if it bugs me in the furure I can have the brake plate  re-done next winter - the Guy at CWC was a  Brummy with the famous patter so I accepted his reasoning that it was old alluminium causing the gassing problem. I had done some preparation on the brake plate beforehand as well.

Despite the warmer weather I am leaving fitting the wheel bearigs until I've done some other household tasks plus some garden work. I plan to ride the 400 as soon as the weather really warms up for me - I can finish  the 500 build if we have a wet summer.  My original plan to have the 500 done for my Birthday in early May 2024 has been put back a month or two.

Never say never -  atm the 500 is my last full project - I've gone off the Maicoletta idea for now as there is a very small pool to choose from with all the attendant parts finding problems. Might all change when I go to Stafford Bike Show as the Maico Owners Club will be there.

I haven't the room for 3 bikes and despite it being too small for me I like the 400 more each time I ride her so I can't bear the thought of it having to go to make room for a  Scooter.

My opinion for what it’s worth Ted. Don’t sell your 400 Ted after all that time , effort, blood sweat and tears. Only you know and can fully appreciate how much has gone into it. Going slow and tinkering away with the 500 will keep you garage busy this summer. Wthrres no rush if you’ve got a bike to ride and enjoy. When both are finished would be a good time to think about another project, if any. 👍

Not  worthy of any photos as it's a pretty mundane task needing a bit of energy with a medium sized lump hammer.
So this morning fitted the front wheel bearings in my 500 hubs.

As well as the bearings being kept in the freezer for a couple of days I warmed up the hubs a tad with one of Wendy's old Hairdriers on full heat as I did not want to risk anything hotter.
I had checked that the new retainer fitted the threaded section beforehand.
After fitting the bearing the new retainer did not want to go in by hand - I started to panic.
I saw that there was a slight bit of thread near one of the four original stake marks that was slightly flattened - probably caught the edge with my drift tool.
I used the old retainer as a sort of thread cleaner after loading it with grease. (I cut four slots across the width of the thread, wire brush and remove any burrs.)
New retainer then went in by hand after clearing out any debris in the grease.

I have a small piece of plastic speed fit pipe with a slot along it's length that I use to hold the retainer in position when fitting the second bearing. It might have been my imagination but the bearings  seemed to knock in a tad easier with the added heat on the hub.

I could not find a torque setting so settled for very tight plus a bit of extra on two opposing slots with a small screwdriver blade.

It's something my late father taught me when I was in my early teens David and have never forgotten.
Not done it for several decades though as I pretty much stopped servicing my own cars twenty years ago.

For the range of smaller Honda threads I have a few taps & dies.

Question (ftp://Question)

Do the rear hub cushion rubbers need to be fitted completely dry ?
I was thinking a light smear of rubber grease might help with fittinng the outer drive part.

Post by: McCabe-Thiele (Ted) on April 09, 2024, 04:36:07 PM
I have fitted the left rear fixed bearing in place together with the short & long spacer & retainer ring nipped up. Spacers all held in place with a piece of slotted plastic overflow pipe to maintain alignment.
My next task is to fit the right rear wheel bearing - my concern is to avoid any chance of thread damage to the bearing retainer threads whilst fitting the other bearing.

I was going to leave the retainer screw off, then fit the bearing but want to avoid any chance of damaging the hub thread as I use a wooden support at the centre with a rubber pad on top.

Would it be okay to fit the retainer ring first and just support that instead?

Is there a best way round to do it?

I plead guilty to over thinking in advance!

thinking it through Bryan  it will make no differance if the sprocket carrier is in place or just the steel retianer ring - same force on the same part when knocking the bearing in - I'll make sure I've warmed the housing up first.

Nice warm day so decided to finish fitting the rear wheel bearings this afternoom, new bearing had been in the freezer in a zip lock bag for a few days, heated the hub center up with an old hair dryer - they knocked in without difficulty using my drift tool. Center spacer held in position with piece of plasic pipe. so it's all good for when the axle is fitted nicely aligned.

Fitted all new drive cushion rubbers into the slots with a very light coat of red rubber grease, D ring fitted using same grease.
Greased  hub center it pushed in by hand but not fully home for the last 2 or 3 mm.

Not sure if it should go flush by hand or if the retainer has to pull it fully home?
I don't want to force it at this stage so have left it for tonight - tea & beer reward.

It might be worth pulling it out to check the D ring is okay - I fitted it as it came I did not turn the D ring inside out.

My rear hub tool for the left hand threaded retainer does not seem to want to fit on the new retainer ring but it fits the old one perfectly wtf is going on here?
It's a DS retainer ring.

Update Fresh day, removed the hub, D ring was undamaged, used some extra grease, it went in easier just needed to tighten the retainer ring to pull it home the last few mm. I used the old retainer as my tool fits this. No big leverage needed on the retainer just screwed in easily.

Just need to decide what to do to about the poor fit of the new retainer in the tool - two pegs line up nicely but the fourth just does not engage by hand - I'm reluctant to hammer the tool to make it fit!

Could it be the DS retainer ring or is it the tool?

Do you mean this retainer and tool Ted?

If so, I recently bought the tool and an aftermarket retainer from a different supplier and the tool didn’t fit correctly, as you can see. When I contacted them, they checked their stock and found the new batch of retainers didn’t fit the tool but the original Honda retainers did. They sent me a genuine Honda one as a replacement which was fine. I wonder if DSS has the same issue?

I've contacted the tool provider who supply the same tool to DS. It appears that the supplier for the retainers were the issue. I've been offered some turned down pins as an option for my tool. I will contact DS and see if they can supply a better part.
The rear tool is a different design to the front one.

The 500 retainer has a different pitch circle so my 400 tool is too small, on the 500 it also holds the rear drive hub in place.

Update DS have tried their tool in the three retainers they have on the shelf - one does not fit the tool. They will not send me a replacement part until they have recived my part back and tried it in their tool!

Just a bit of an update and to give credit to Vince Goosey at this firm who I bought my lock ring tool from back in May 2023. www.gbmotorcycleproducts.com

I today received f.o.c. a set of four pins to replace the ones in my tool that fits the poorly made replica part supplied my DS.
That's what I call customer service.

I decided against sending my lock ring back to DS for them to change it as they were not prepared to do so until the faulty part was back with them to compare- clearly they still have the faulty ones left on the shelf. I did not want to take the risk of them sending the same part out again not to mention the time delay.

Clearly DS knew there was an issue with a batch of their lock rings - they could have sent me a replacement that I would have paid for on the basis of a refund on the returned part. This was an opportunity for them to give better customer experience that they missed.

This morning I tightened up the lock ring with the new pins fitted to the tool.

It's clearly not my day today.

Well, came to fit the oil seal in the retainer and it does not want to fit - it clearly is the right size as it looks as it will fit the old retainer just fine when I tentatively part fitted it!
I dont want to risk damaging the seal trying to make it fit so I am sending the retainer back to DS for replacement.

That's put me back a few days now - I am going to return the DS retainer ring part in the hope that a replacement one is from the new production batch.

Ted, for the life of me I can't remember an oil seal sitting in the retainer. The only oil seal fits in the sprocket fixing plate which the rear wheel collar comes through.
This is a 550 but should be the same.

But I might be wrong!

My 500 has eight rubber dampers four are thick on the drive side four are thinner on the overrun.
Looks like the 550 is different.
Definitely another seal on the retainer item 20 in the parts book p/n 90753-283-000 the left side spacer runs inside it plus a large O ring for the sprocket cover I think.

550 and 500 same shape but later ones had a connector bit, the screwed in retainer does not have a seal, only the big tim pressed plate

So the seal fits into the sprocket cover plate Bryan not the retainer ring - that makes sense.
It confirms what seablower said as well.

I should have taken more photos and listned the first time!

Plan C now used the DS retainer ring having fitted the different pins to my tool - tightened up nice and tight - all looks good

The 500 rear wheel when fully assembled felt so much heavier than the 400.
Seal fitted into the sprocket tin plate after fitting the left side spacer wide end to the bearing. Large O ring fitted to the hub all in place as per the parts exploded diagram.  Spocket nuts nipped down with some new locking washers fitted.

I've done the first fit of the wheel - looking good - not torqued up the sprocket nuts yet or bent the locking tabs into place. I'm worn out now for today.
I'll tighten up the rear axle to check the wheel rotates freely before I fit the chain etc.
