Title: OAP Ted's CB400F2 rebuild - engine not run for about 12 years.
Post by: McCabe-Thiele (Ted) on August 29, 2020, 05:32:01 PM
Okay so here is my Honda CB400F2 purchased via e-bay from a local seller who unfortunately knew they fetch fair money so it was no bargain at £2000 as a thrown together to sell bike- looked good in the sale pictures. It came with a box of new parts with invoices spanning just over 10 years of accumulation. The box of new parts had a retail list price of just over £300 with some new or good used parts already fitted. As it was quite local I did go and look at it before I ended up buying it as it was the only one I had found that wasn't at the other end of the UK or out of my price range (Optimistically set at £1000-1500).

The seller declared that he bought it from a relative some 12 years ago with a rattling cam chain - he lost interest when he bought a Harley so by the time he got round to fixing the Honda ill health had prevented him from biking again so he decided to sell the unloved Honda.

It does crank over on the kickstart with reasonable compressions - certainly enough to get it running before the full rebuild ahead.

Looking forward to your progress, the bike actually looks very clean and tidy in the pictures, good luck.

I struggled resizing pictures as well, I use PicResize now - https://picresize.com/# (https://picresize.com/#) and reduce by 25% seems to work.

The photos are flattering the wheels rims are pimply, spokes have some rust & the hubs have the usual aluminum surface corrosion.
The coils were completely shot with some old fuel in a very rusty looking petrol tank. At least it came with a new battery & I got the electric starter working once I had reinstated some wiring.

It's given me something to do in my retirement - so far it's been more of a learning dip than a curve I can't believe how out of touch I have become considering I had a very long background in the automotive industry. I used to fit heaters & do pre-delivery inspections on new Vauxhalls when I was only 14/15 years of age - were talking FB Victors & HA Vivas here. lol

When I sold my Austin 1100 in fetching dark green circa 1965/6 I took a Red hand painted HA Van with a single mattress in the back as part exchange!

I tried sleeping in the van when I went camping but it was too darn cold - in my defence I was single at the time.

The HA Van & Vivas were very quick 0-15 mph then it was game over  - no stopwatch needed for 0-60 times more like a calendar.

Back to the build my first hurdle when looking to start the engine was that the throttle was solid it would not open the main throttle as all the slider things were seized solid. The seller assured me he had cleaned out all the carburetors but that must have been a decade earlier.

When I stripped down the carburetors all four of the  main throttle valves were stuck solid in the closed position. Not wanting to damage anything I released the first one using the wife's nail varnish remover - this worked quite easily but the other three did not respond to the same solvent.

To release the remaining three I fully immersed them in fresh petrol in a Tupperware container fitting the lid and soaking for 48 hours. This worked fine on two but for the last one I replaced the fuel again leaving to soak fully submerged for another couple of days. After a bit of heat from an old Hair Dryer when the fuel had evaporated the last one came free. All rebuilt last week after a slow start when I tried to fit a jet into the place where the float valve clamp screw fits.lol The parts were all cleaned in my Brother-in-Laws Ultrasonic Bath - its done a fair job I have to say though he did say that there were other ways costing more money to return them to almost as factory  new. At present I have not explored this route as I am not looking for show standard just a good working bike. I fear this might change if I see too many mint 40 year old bikes.

I pushed the boat out and bought a Dynatek Electronic Ignition Set with Coils etc - I have fitted this just need to set the static timing when I am nearer trying to start her up. Coils were an easy fit using the old coil mounts with a bit of modification with a junior hack saw & drill driven cutting wheel. - they clear the fuel tank so so far so good.

Carbs now re-fitted at present using the existing throttle cables for the initial start up phase. I'm waiting for some fuel hose - I will use this time to clean the petrol tank a bit more. My heart sank when I first looked inside the tank but after putting in some Turps substitute (rather than water) and some 2-3 mm grade silver plant gravel its cleaned up enormously after some shaking sessions.

Yes the HA had the Sardine Can Top to the wings it was the later HB that was rounded.
I took my test in my Dad's Company car an almost new Vauxhall FC 101 Victor Deluxe same type of wings as HA!

My bike doesn't look like a genuine Honda Blue colour for a CB 400 anyone know if its a Honda shade ?
Title: Petrol Tank fuel tap removed.
Post by: McCabe-Thiele (Ted) on August 31, 2020, 12:29:51 PM
As the petrol tap seemed to be unable to pass the blow test I removed it to find the strainer had been damaged  & put back all twisted, the top of the tap was solid with crud and perished rubber.

I still have more rust to remove from inside but clearly if new bits can't be purchased for the tap will have to shell out for a replacement.
I'll put some of my silver gravel in again and do the shakey, shakey, shake routine until my arms ache.
 
Any advice as to best source for a replacement is it DS or DS for a petrol tap ?
Cheap one below knowing my luck it will not fit thought the CB400F2 is listed as suitable.

Work has ground to a halt due to an overnight stay in local Hospital - I had Merlot posing as Urine then must have passed a kidney stone the pain was the worst I have ever had in my life - including a fractured femur when I was 18.
Had a scan of my kidneys yesterday waiting for the camera jobby to check my bladder out. Oh the indignity I have to face within 14 days as a day patient!

Anyways I'm tickety boo today but am stuck until some bits & the Electrolyte arrives for my tank cleaning task. Still awaiting a sellers  response on a cheap Petcock.

Erm, that doesn’t sound like a whole lotta fun. Glad to hear you’re on the mend.

Personally don’t like the look of the eBay petcock as it’s riveted together - tho’ in truth should not be a big deal I guess. As a general comment, the more you deviate from OEM parts the harder your bike becomes to maintain... as any adjoining part then needs a bit of modification to fit. (bladder bone connected to the kidneys bone as it were 😂)

(In this case the hose dia may be different to the carbs?)

What electrolyte are you waiting for? All you need is some bicarbonate of soda.

The other thing to try if you’re not in a hurry is white vinegar; it is very cheap (<£20 for 20L on EBay) and avoids all the hassle of fashioning electrodes shaped to reach the deeper recesses of the tank. The one advantage of electrolysis is that it only attacks the rust, not the good metal underneath.

Just pour the vinegar in and leave for a few days – depending on the degree of rusting – pour it out, but not down the drain. If you’re not happy just pour the vinegar back in and wait some more. If there is a lot of deposit in teh vinegar you can strain it using a kitchen sieve.

You can also use Citric Acid (available everywhere and as cheap as chips). It is the main ingredient in Deox-C. We have used Citric Acid with excellent results.

Electrolyte works well but can be fiddly fashioning an electrode and an insulator, currently being discussed on another thread... Recently i have used “evaporust” to good effect. Pro’s its re-usable and can be used on any ferrous items.. con’s its a bit expensive at 30 odd quid for 5 litres.... magic stuff though, not acidic at all....works by breaking the iron - oxygen bond, clever stuff.

In reality I guess the Citric Acid is just there to produce ions to allow the current to flow so many alternatives can work. Obviously not Table Salt as that would give off Chlorine gas as opposed to Hydrogen at the Electrode (Anode end ?).

I bought some white vinegar a few weeks ago with a view to trying it - then read loads of reviews saying it does not work! We having it on our Fish & Chips instead. lol

I can't find a petcock that isn't riveted together.  DSS is offering a "genuine" one for £47 - it's riveted and in fact looks identical to less expensive one I got from 4into1... which leaked the first time I used it, BTW...  >:(

EDIT: I'm talking about the '77 USA version...

Don't forget a' genuine' part is not an 'original' part. All genuine means in this context is that it fits other Honda's, including the 400 Four

 :-\

I'm not sure I understand what that means, in terms of a retailer like DSS who is generally offering two types of parts, "genuine" and "aftermarket."  As a customer, I think that "genuine" would mean made by Honda, or by the manufacturer that originally made them for Honda (which DSS appears to call "OEM Replacement").

If "genuine" simply means that it fits, couldn't any part - even an aftermarket pattern part - that fits be called "genuine?"

No, the 'genuine' parts that the likes of DS sell are genuine Honda parts but that is all it means. If you are looking for a replacement for an item on your bike to replace what was fitted when new, you need an original part. Genuine just means it's genuine Honda , will fit as a replacement part, usually to lots of different Honda models, and do the job but it is not the same as the original part.
After market (pattern) means its made by anyone else, not Honda and is obviously not identical to the original part fitted to the bike but, it does the job.

If you are looking for an 'original' 400/4 pet cock, CMSNL do one. It's the correct middle part number and is an original part. It's not cheap though. This is why when restoring a bike with Original parts, it can costs a bloody fortune but, if you want it correct, that's what you have to do.

I'm okay with meandering / hijacking threads as there is usually a good point or nugget of information in the process.

There is a genuine Honda Petcock on e-bay with what looks like the right part number at £75 starting bid - it had no bids on previous listings. If it is NOS the rubber seals might be perished.

Can you get the O rings for the tap as that and the strainer/filter would do for me ?

The eBay link you posted above Matt is the same fuel tap that DS sells for the 400/4.I did cross reference the DS part number a minute ago and I see it fits loads of different Hondas. I wouldn't know if the original one I posted a link to on CMS would fit a USA / Canada model, I must admit, I thought all the original taps were the same on all market models but maybe not 🤔

I don't know about all market models either!  I'm definitely no expert here - although I have learned a lot about the differences between the '77 USA and all the other models...

I do know that CSML's 1977 USA listing shows a different part number, and a different-looking petcock, which I showed in my earlier post.  That's why I mentioned it - that Ebay link was the OP's, I wanted him to make sure he was really looking at the correct part.

If you have a copy of the Honda parts catalog which includes CB400F, CB400F1 and CB400F2 "under one roof" (available in 2 different versions at this link (http://www.honda4fun.com/materiale-documentazione-tecnica/parts-list/parts-list-cb400)), you'll find the different part number for just the USA/Canada F2 models: 16950-377-701.

That's weird, as it says that part number fits a CB125T2 ENGLAND PA.COCK.F, CB405F. But, there is then a supersession # being 16950377702 and that number shows the riveted type like you posted a pic of earlier. I really can't see what or why there is a difference in the original part though for USA/ Canada markets 🤔🤔It could always be an error in the original parts list translation, there are plenty of them in the parts manual.

I can't either.  The "multi" parts manual I referenced earlier even has a separate "exclusive parts for each area" section which details some of the USA F2's idiosyncratic differences - like the single-stayed front fender, the different foot brake and shift linkages, the exhaust header attachment collars, the hideous fuel filler "door" - and the apparently non-serviceable (riveted?) petcock...

I can't either.  The "multi" parts manual I referenced earlier even has a separate "exclusive parts for each area" section which details some of the USA F2's idiosyncratic differences - like the single-stayed front fender, the different foot brake and shift linkages, the exhaust header attachment collars, the hideous fuel filler "door" - and the apparently non-serviceable (riveted?) petcock...

Have you asked the 400/4 owners on the USA forum what tap they have fitted?

Nope!  :D

I hadn't given it any thought - until just a couple of days ago when my brand-new (but cheap aftermarket) petcock I got from 4into1 demonstrated its inability to keep fuel in the tank...

Got me a bit worried again now...
I've got three 400 tanks and all have a 20 x 1.5mm thread on the underside but everyone I check with only do a 16mm tap for the 400.
Googling to extreme boredom the only option I could find was one from the US - from 4 into 1 - which I ordered and is somewhere in transit at the moment.
Real pain if this turns out to be no good

All this mystery with the fuel taps is telling me to respect the original one I have fitted to my 400/4. There are enough dramas going on in the world at the moment without me getting in a tiz over a tap 😁😁😁😁

4into1 sells 2 different size petcocks for 400's: the 20mm x 1.25 for '75-'76 models, and 14mm x 1.0 for '77 models - both "genuine" Honda and aftermarket currently in stock for both sizes.  The 14mm one fits my '77 USA tank.  Do you know which size you ordered?

I've finished with the gravel bit - loads of stuff came out.

Question do I have to drill out the end of the pin / rivett to remove the cap - can you buy new pins or is there a better way forwards?

Yep, you’ll have to drill out the rivet - if you want to do the job properly. Replacement rivets avail (I used DSS) and fairly easy to fit, though you have to be bloody careful not to damage the paint (obviously).

I'm a bit at 6's & 7's today as I've had some pretty heavy news on my health front that's making me re-think my strategy for the build timetable. What started as a bit of blood in my Pee last week has turned nasty upstream in my kidneys - the Consultant was talking today about me having my right kidney removed. I guess that's something they don't joke about.

I'm thinking now to just get the engine running as planned if possible by the end of this month. Then I might have to abandon the planned full strip down & go instead for an Oily Rag jobbie so I can ride it when the cam chain & clutch have been sorted.

For now I've ditched the Electrolysis Petrol Tank Clean and gone and tipped 5 Litres of Evaporust in the petrol tank today. That can work its magic whilst I have CT Scans etc etc. Hey I'm 72 I know my three score years and ten are behind me but this was a bit of a sucker punch. Sorry to burden folk here about it but a problem shared and all that.

I will keep on dipping in and out of the  Forum to keep up to speed with everyones bike build progress. Cheers for now  ....Ted

Agreed. Everything you planned to do will be waiting when you get back to it.

Sorry to hear about your kidney issues.  Doctors are smart these days, though, and one kidney is all you really need - I know of a few very selfless donors who can vouch for that!  My ticker wandered off into the weeds on me a few weeks ago - one surprise pacemaker installation later and I'm about back on my feet again - here's hoping for the same type of result for you!!!

If its warm this afternoon I'm going fishing to a lovely local lake where I am a club  member - no kids allowed just brilliant scenery and wildlife - catching a decent sized carp is just icing on the cake.

I'm back on with working on the bike - going to remove the Evaporust today - then add some petrol with 2T oil to give the tank some inside protection.

As its sunny and getting towards the back end of the Carp season I'm fishing this afternoon - planning to fit the tank tomorrow and sort out the static timing.

Starter button pressing hopefully before the weekend.

Had a good phone call yesterday from my Urologist who says the CT scan reveals no further problems with cancer spread - right kidney removal should be in the next 4 weeks - end of October by the latest provided Covid does not mess up admissions.

Thanks everyone for your support - now it's all about the Bike.

Last night I drained out the bulk of the 10 Litres of Evaporust - I  filtered back into original containers as its not fully spent yet.
Results are amazing - shame I can't get my phone into the tank - its 98% like new everywhere I can see clean silver metal!
The bit that's rather patchy is what I would describe as the inside hump near the filler cap - it has a few spots near the top of the ridge hence I can't call it 100%! Trouble is it needs about 13 Litres to full it right up - maybee another time.

Drained out the last remnants of Evaporust this morning - now the first rinse out using a pint or so of fresh petrol, 325 ml of Wynns Dry Fuel plus 1/3 pint approx of 2T Oil.
I will slosh that all around to try to inhibit any further rusting.

It's a strange thing but as I am approaching fitting the tank and getting close to an attempted start up I feel myself slowing down fearing unforeseen issues. I ought instead to be estatic at the prospect - is this normal !!

Knowing my luck the Carbs will decide to flood just to set me back a few days. Wish I had tested them with fuel before I refitted them now!

This Friday all things being equal it will be fitting the rebuilt Petcock and putting some proper petrol in the tank!

I understand exactly where it comes from, for me.  Start with a bike I know wasn't running all that well before it sat for 3 years.  Add to that a bunch of repairs and adjustments - to a bike and to systems I'm not too familiar with, and therefore don't have a lot of confidence about.  I hope for the best, but assume things will go wrong...

Another step closer today - re-fitted old Petcock with new tank strainer used the old seal but have the two that DS supplied - petrol tank back on the bike - 4 Litres of new Super Unleaded tap into Reserve position petrol filled the little in-line filter all looked okay for a minute or so then petrol started coming out of two of the overflow pipes. Big curse to myself !

Walked away wishing I had checked the carbs with fuel before I re-fitted them to the bike had a moan with a mate who said - have you tried a gentle tap on the carbs incase the floats are just a bit stuck as they were completely dry. Did just that followed by shaking the bike from side to side - fuel back into reserve no sign of any more fuel from overflow pipes. I've given it a good 5 minutes and no more fuel out of any of the overflows. I feel happy that's good enough for a planned initial start up.

I've checked for spark - nice visible spark at the old dirty spark plugs - I am now ready to check the static timing tomorrow morning then its new plugs in place and see if she will run. The new plugs that came with the bike are NGK D8EA as are the old ones that were fitted.

Fingers crossed for tomorrows start up attempt !! :)

Set the static timing this morning took me about an hour to get it all done plus 30 mins spent making a decent loom connector & test lamp to set 1&4 then 2&3.

Cranked her over having got the oil light out first with no plugs fitted - plugs in after a fair bit of popping & banging she started to fire - more choke less throttle and away she went. Only a brief video but I am ecstatic !!

Hope the brief video works.

Not really done much since I've had the engine running, as the clutch will need to be stripped down & replaced I thought I would see if the casing screws wanted to come out. Removed the brake pedal & kick start for full access - just needed to find out if there were going to come out or not. The plan is/was simple go round getting each one undone then hand tighten ready for when I drain the oil & remove them all.

Tried by hand - got nowhere so got out my Kielder 1/2" drive impact driver with a new long JIS bit fitted via my hex adapter. They have all come out with ease. Only loosened them a few turns then nipped them up by hand ready for oil drain and strip down hopefully over the next few days.

My nightmare experience back in the mid 1960's of removing similar screws on my Honda 250 Dream with a hammer & chisel or drilling them out are now history.  RESULT.

Assembled the clutch basket today I have the flat edge of the plain metal discs facing the engine with the notch marked discs all facing outwards and together. The smaller friction disc is against the retaining clip. All looks good.

I've dismantled the camlifter clutch operating unit in the clutch cover case - the bit with 3 large ball bearings fitted with a bearing race holder thing. It looks badly worn but looking at pictures they all look strange in that the balls sit in an oval looking recess. DS says parts not available but their pictures show a worn like oval seat  so I guess its the design!

The learning dip......................

Having assembled the clutch unit I've started to realise that I'm not taking enough photographs as I dismantle things as I should. I think to myself its obvious how this fits - then a couple of weeks later I find myself wondering how it all goes together again.

In my youth I could strip down a Mini Cooper S engine & gearbox - change a synchromesh using the manual only for torque settings and the like! Not sure if it's my age or that more modern motor cycles engines are so much more compact.

I have two workshop manuals that came with the bike - I am finding that they seem to be written for folks who know what they are doing.lol 

Thank goodness for this brilliant site.

As I have no date for my operation with indications that it will not now be until late November due to a backlog in Urology/Covid consequences I've now started plan C roughly as follows.

When the clutch casing has been re-painted & replaced I am going to do a final compression test both hot & cold to help me decide if a full engine strip is really necessary.

I am aiming to then remove the engine & put it on its NJ sourced stand, get as far as possible with the full frame strip down to enable powder coating.

I am guessing the engine is pretty heavy - so can it be removed complete or do I need to take off the rocker cover?
Any tips for getting it out of the frame please?

Oh yes, it will come out in one lump very easily with 2 of you Ted. I assumed you would be doing it on your own and didn't want you to get a double hernia on top of your other issues 😊😊😊

If there was room for bodies & hands I can get 2 to help me. Too late for a hernia warning they found a small one when I had my last scan. I've no idea how I got it as I'm very careful when I lift anything - I don't do heavy. Lol

Too close to the truth in that comment John - if I carry on at my present spending  rate I will have spent more on parts than I did on buying the bike in June 2020!

Since lock down I've done the accountants / auditors  trick - my eating out budget, fuel budget & holiday budget have been subsidising the bike build so it's not really costing anything - just swapping budgets with a small net saving.lol

Bit of an update on the project.
When I first started the engine after it's 12 year rest it started pretty easily this has in part led me to believe that maybe an engine strip down was not needed. (Clearly in denial here)

Since that first start up it has taken a lot of more cranking to get her to fire up - this has led me to suspect that the compressions are not that brilliant. A cold check on 25th Sept 2020 revealed that the compressions were a pretty even 90 psi on all cylinders rising to 110 psi when check some days later.

Yesterday I just could not get the engine to start so this morning I squirted some 2T oil in all four cylinders with a view to re-checking both cold and hot compressions. The first thing I noticed was that when I cranked the engine about an hour later without the plugs in place almost no oil was pushed out so it had obviously drained through the piston rings I am thinking. Another cold check then revealed 205 psi on cylinder 4 I didn't bother check any others I knew the truth already.

When I replaced the plugs the engine fired up fairly easily so I let her run until up to temperature then did a hot check on cylinder 4 - it was only 120 psi. Clearly I am loosing compression with the rings / pistons being the main culprit.

Obviously I will need to carry out an engine strip as the compressions are well below par. Just as a point in case the engine does run quite nicely in the circumstances especially considering that I have not adjusted any idle air screws.

I now intend to crack on with the strip down of the frame ASAP hopefully I will get the engine out before my operation that still has no date due in part to the effects of Covid on ICU bed availability.

Just for the craic I have recorded some engine running earlier today to keep me enthusiastic I will post a link shortly.

Could not resist a bit of revving - smoke is a mixture of 2T oil burn off and hot oil spilt on the engine. It will be next year now before she runs again (hopefully).

Are you sure about the 205 psi on No 4 Ted. I know what you mean about a successful engine run making you overly optimistic. Had my engine running 3 times now and started to think I'll leave the carbs alone it's running great. Last run petrol was pissing out from No4 overflow pipe. However I didn't use your bike rocking technique on this occasion. Anyways clearly the carbs WILL need attention. Good luck with the fun part of moving from fiddling about to taking to bits!

Post by: McCabe-Thiele (Ted) on November 09, 2020, 07:58:22 PM
Clearly the 205 psi reading is unlikely to be accurate. The gauge was less than £12 so it's a relative rather than absolute.

I've substantially stripped down the frame so I can remove the engine hopefully on Friday when my younger brother (by 10 yrs) can help lift it out.

The sump pan had some rusty grey deposit in the bottom with an odd little pipe on the oil pick up strainer - not sure what that does though.

If you look up into the bottom of the engine you'll see a spigot that the "funny little pipe" pushes onto.
Part of the oil circulation system.

My pipe had no clips just a push fit with a pipe showing it's age with a lack of elasticity - I guess as it's under suction so no need?

I will need to replace it for sure.

Mainly due to storage considerations I've decided to leave the engine in place in the frame probably until early next year now.

Still toying with the idea of removing the cylinder head & barrels in situ but seeing NJ's build I don't want to hit head nut issues at present so might leave it as is.

Can't leave it alone so yesterday finished oven baking the sump. Baffle plate was slightly rusty so it had the "Evaporust" treatment as I could not undo the holding screws it was done in place over 2 days. Decided against grinding out sump scuff - left its lightly battle scarred looks on the fins.

Still doing a bit of tinkering - had a look at the camshaft cover with a view to painting it. I was surprised to find it has the rocker shaft in it as well as acting as half of the camshaft bearings.

Pleased to find that there was no undue wear on the rocker heels and that the rocker shafts were in good condition. The visible parts of the camshaft lobes look good as well. This confirms to me the mileage of 32,600 is genuine.

Just shows how well they were engineered I guess - back in the 1960's BL A series rocker gear was always well worn even at fairly low mileages.(https://live.staticflickr.com/65535/50619408008_b514a396ba_k.jpg) (https://flic.kr/p/2k84GrW)camshaft cover (https://flic.kr/p/2k84GrW) by Teddy Bagshaw (https://www.flickr.com/photos/186528626@N08/), on Flickr

Thanks for the various ideas .....Presently draught proofing the garage eaves with glass wool type insulation. Nice brush seals for the top of the up & over door.
Presently costing ceiling insulation in 50 mm Kingspan type material. Then its the multi layered insulation on the double door.
Dehumidifier is doing it's stuff during the presently humid & rainy weather.

Entry is only by the side door via my office annexe at present.
As our large upright garage fridge plays up when the ambient temperature drops below 50 F I can justify the cost as it will make the fridge work all winter Wendy!

I'm easing my way into the garage by stealth. lol

So this morning as Wendy was working a double shift to book Covid19 jabs at the surgury I decided to look at doing some light easy jobs   prior to engine removal. Safe in the knowledge that I would not be "found out" I decided to start with undoing the cylinder head bolts.

I had wories about super tight bolts etc so began loosening in sequence as per my manual  - to my surprise they have all come undone without any issues. I haven't looked up the normal torque settings but most of them were around 10-15 lb ft maximum some were almost finger tight it was that easy.

As I have no plans so far to split the engine case just remove the head & cylinder bores am wondering if it's best to tie up the cam chain and replace it when rebuilding as I am fearful that if I take the cam chain off completely now feeding in a new one will be impossible.

This is all a bit unknown as I might have to split the casing to replace the drive chain eventually anyway. Any advice is welcome.

As you suspect,  chain is endless so needing to split cases to slide a new one onto crank is unavoidable.

It's very low risk if you drop the chain inside,  just don't rotate the crankshaft until you've fished it out again.

Retiming is easy on these,  with the top off the rockers are removed making no interference with valves and pistons possible.  You can rotate the crank and camshaft till the cows come home to check you've got it set right.  Only then do you put the rockers in their cover back on to "activate" the valves. 

Worthwhile checking with the cam cover off for chain wear though.  Give it a lift at higher most point to see if the links lift away from the sprocket. It should have very little slack at that point.

My bike purchase came with a new timing chain supplied but it has a link so was thinking I could remove a link on the old chain then feed it through attaching the new chain ?

Maybee folk are against a split chain ?

Lots of people use the split chain for convenience.  The disadvantages are not being as secure as an endless chain and not able to check the cam chain tensioner operation.
If the primary chain has never been changed it probably needs doing now.

It's done around 32k miles I'm guessing the drive chain is original.

Don't understand why checking the cam chain tensioner operation is an issue with a split chain ?

Some of the older (than this) engines routinely use a joined chain, although I believe with a specific tool to set them. Illustrative of potential if they're ok.

I'm fine with hand peening to join things like final drive and mtb chains etc with no reliability problems.  But, possibly irrationally, I still would choose continuous for cam chains as failure in any significant way will just make you weep with the distruction.

Depends also how you look at the task of splitting to replace. I feel that's easier to contemplate than the thought of distruction  :) and would thoroughly clean the outside first if you are not going for a complete strip. It's really just taking the bottom case off and undoing the rods,  lift out crank and swap chains, then torque it back together.

At those miles the primary will usually need replacement too, with the two contributing to how these engines sound when running well more than most components. 

I suppose I don't look at changing them whole as a chore,  more that I feel it's nice to work on them.

Julie's thread on rebuilding gives a very good look at making sure the tensioner works correctly if you've not already seen it.

tbh I share worries about a chain with a split link so realistically I will split the casing and change both chains.

At present the cylinder head does not want to lift off as the cyliner block is lifting instead.

What's the best way to seperate the head from the block without damaging any fins ?

Hi Ted, glad to hear your'e back on the bike! If you do choose to join the chain, have a look at mine to see how it came out. Having split my engine I can see the cases haven't been split before but the cam chain has been replaced. The image shows how badly it was done. My tensioner arm is also completely seized, however I think your engine is in better condition especially so if you were able to adjust the tension or didn't have a rattle in the first place.

"What's the best way to seperate the head from the block without damaging any fins ?"

You can try (if you've got something like the big flat tire levers) to carefully push that in to the root of the fins right by the gasket surface at each end, and gently twist them,  not try to lever.  It at least assessess (is that correct with more ss's than Mississippi? ) if it's going to move or be more reluctant.

Once the gasket seal starts to come apart they are usually ok. It's not to use much force but more gentle encouragement at the right location, if that makes sense.

The levers sound potentially risky though clearly it has worked for you.

I'm currently in deep thought mode for my next move.

Yes certainly,  but with acknowledging where the castings support themselves in vertical load rather than the end of the fins, which will guarantee breaks.

Hopefully you'll not need them if they come apart.  The head gasket (in description of sticking in other thread) will hold quite well if assembly is correctly done and surfaces degreased as Honda usually placed strategically important "tacky" areas near to oil transmission routes in getting non leaking assembly.  It's not massively strong,  but is designed to have a sealing integrity as you describe.

Thanks smoothoperator for the tip - I used a plastic wedge as used by double glazing fitters and gently tapped it int on outer corner. Fed plenty of WD40 into the gap - in a series of tapping the wedge with a rubber mallett and removing it then tapping the head all round it finally let go!

The cylinder head has been off before as there are small witness marks from a chisel or screw driver on both sides. So far looking good - the head gasket is a black material - no sign of blowing anywhere.

I suspect that the exhuast manifold head connections have been leaking with the blow by building up a carbon deposit causing an external bond between head & cylinders.

The engine has clearly been running rich either beforehand or since I had it running.

The whole thing doesn't look bad at all really.  Looks like it's been well oiled from the components on view, even the cam looks as though it's been run with correct clearance for valves from that cursory picture of it.

Head gasket all seems to have been running with no leaks, indicating competent last intervention from whom so ever.

As you already recognize,  it's been running "generously" jetted with that colour and carbon.  For some time too, as you can see the "correct" colour of exhaust valves as undercoat  !! with a fair thickness of carbon on top of that.

If the rest of the components follow suit,  then it seems like you've a decent one.

More frame stripping, handlebars removed, frame supported on wooden blocks to fascilitate front wheel removal. Noticed the steering was like a three-penny bit when wheel removed.
 
Both telescopic fork legs removed together with top & bottom yokes plus searching for lost ball bearing that went everywhere - so far I think I have recovered 34 in total!
My Haynes manual reads 37 off - odd total. They will need replacing anyway due to general rusting, likewise the bearing cups etc.

Update I have now found 36 of the ball bearings !

This morning having examined the steering outer bearing races have decided they need replacing due to rust etc -  upper & lower bearing surfaces drifted out with ease.

No key for the steering lock so old one drilled out (followed guide on a previous post here to choose the hole position) - kept the spring as not sure my new lock has one or not.

Hardest job today was removing the brake stopper/stay pivot bolt from the rear swing arm. The inside nut was well rounded so had to cut the nut off with junior hack saw. If they are readily available I will get a new one as it's a sholdered bolt with a narrow top head.

Only item left on the frame now is a wire hook thing near the steering clumn on the rhs- I guess its a wiring /cable run retaining hook of some sort .
Rear swing arm bearings nice and free - move out by hand pressure  so they will be pushed out to check for wear. I suspect they have been replaced at some time as they are too clean & well greased.

Next is thinking time to decide if I'm sending the frame for powder coating or if I'm going to flat it down & rattle can paint it. I have decided I do not want black - thinking of a midnight blue instead.

I'm back inside as it's pretty cold in my garage today - just made a Kidney Madras sealed meat first then sauce out of a jar - its' in the oven for tonight as Wendy has been called into work again for Covid Vaccine administration work.

It was bitter cold in my garage today so all I managed to do was remove a broken off grease nipple on the rear forks.

As I started to drill it out it rotated freely screwing all the way down instead, I reversed the drill action - it almost came right out.
Last few turns done with the aid of a hammered in allen key and out it came.

Not very exciting I know but in the grand scheme of things just wanted to share my good luck.

Good work Ted, no use rushing. I've brought bits up into the house to clean them up, much to cold in the garage.
As for your frame, I have just sent the z400 frame to a company in Windsor called Microblast (they advertise in Classic Burke, sorry Bike 🙂). They have quoted me £300+vat to blast and powder coat the frame, swing arm, main and side stand, yokes, headlight bowl and 31 yes, 31, brackets (Kawasaki knew how to make a bike heavy!). Turnaround time is 10days. I'll let you know about the quality when I get it all back. The price includes some parts that are satin finish.

I used to be undecided but now I'm not so sure. lol  Talk about "U" turns.

I visited Langley Coating a firm just a few mies away I took my frame to have it shot blasted only or possibly primered to stop it rusting when I get it home. After speaking to John the Motorcycle Man I decided to get it powder coated as they had the exact colour I wanted - far from original Honda it's going to be Sapphire Blue Gloss RAL5003.

I plan to paint some of the smaller parts myself in Rust-Oleum Gloss as I'm not too fussed about shading differences. They are pretty busy so it's likely to be a 14 day turn round if I can get the stand to them on Monday.

The idea of Gold alloy wheels gets more attractive every day with some mean tank & side panel custom graphics - it must be the red wine has blurred my thinking tonight.

I used to be undecided but now I'm not so sure. lol  Talk about "U" turns.

I visited Langley Coating a firm just a few mies away I took my frame to have it shot blasted only or possibly primered to stop it rusting when I get it home. After speaking to John the Motorcycle Man I decided to get it powder coated as they had the exact colour I wanted - far from original Honda it's going to be Sapphire Blue Gloss RAL5003.

I plan to paint some of the smaller parts myself in Rust-Oleum Gloss as I'm not too fussed about shading differences. They are pretty busy so it's likely to be a 14 day turn round if I can get the stand to them on Monday.

The idea of Gold alloy wheels gets more attractive every day with some mean tank & side panel custom graphics - it must the red wine has blurred my thinking tonight.
As in Kirk Langley?? Let me know how you go on as looking for someone local for my frame etc. What are they quoting for the work if you don't mind sharing that?

Yes they have a website with some bike frames pictured - its a spin off from Langley Gates I think.  I will post a photo when it comes back home!

I will PM you when I have paid at the moment its not a fully firm - estimated price looks like £160 plus VAT at present.

Collected the frame this afternoon - looks brilliant so far I have to say.

If it's still as good when it's unwrapped I will be well pleased.

It's clearly not a Honda colour but its Sappire Blue Gloss RAL 5003 as I specified.

Having examined the frame my only gripe is they have made the stamped in frame number completely  illegible - it's a niggle because I was asked if I wanted it masking off so the original frame area would show!

I had removed the rivetted on plate so its not the end of the world. Too cold again here to start doing any rebuilding.

Looks good Ted. You are at the same stage as I am with the Z400 rebuild. I collected my frame on Monday along with the swing arm, yokes, stands, headlight fowl and 28 brackets!
I spent today giving the wheels a final polish and cleaning/de-rusting the discs prior to fitting.
I'm going to start reassembly tomorrow.
Keep your progress photos coming, gold wheels always look good👍.

I wouldn't be happy about those 2 marks on the L/H footrest hanger.

Got to be honest Ted and say the paint looks a little thick, around the lower engine hanger bolt hole it looks like they didn't mask those off and it's possible the bolt won't go through now.
The marks on the footrest hangar are an odd reflection from where the steel frame profile changes there is no physical mark. I agree the coating thickness is certainly not thin. At £155 incl VAT I think it was good value. I expect that I will need to probably clean out some of the bolt holes for a free fit but threaded sections appear good. Presumably a little abrasive action with some wet & dry using a circular profile dowel will not be too difficult - tbh had I painted it myself I might face similar issues.

Hope I don't sound too defensive - I mostly accept your comments.
PS
What I have discovered on closer examination is that the rear offside footpeg frame bracket has a bit of a bend in it - tbh had I noticed it beforhand I would hve applied some heat to straighten it. As I will never have a passenger anyways it's not the end of the world but shows the importance of a thorough inspection beforehand - now I think about it the rear footpeg was at an odd angle when folded back - I dismissed it as wear in the bolt/spring mechanism.

Aside from fitting the steering shaft I was going to leave the frame alone until the engine has been further inspected. Should I need a rebore or any other major work I can then fall back on frame assembly to fill in any waiting time.  I need to plan my work space out better as I was going to have my engine on the bike lift and put the frame at the end my garage. I might have to reclaim my work bench behind our car in the garage for engine work.

Main lesson I have learnt so far is to check your frame fully before painting - see my post about the bent rear foot peg bracket. Not sure yet whether to live with it or sort it now.

Still very cold here just 6 deg C.

Today I have dropped of my upper crankcase to have the cam chain tensioner repair/upgrade fitted of the type shown below that I read about here. The local place I was going to use were not happy about tackling it as its at an angle not horizontal or vertical so they recommended a nearby firm called "Croft Engineering" that I am using. I was encouraged when I visited as there was a customer there that was having a pair of engine blocks made for an old 2 cylinder Velocette

This is my Stage 1  inside clean of the lower crank case using initially some engine degreaser, followed by petrol done outside when it was warmer last week. The majority of the paint has been removed just need to fettle it up a bit where the stripper / and or me has missed it.

As I am waiting for my order of Plastigauge & some main shells I have decided to start cleaning up the light surface rust on parts of the gearbox - I don't want the rust deposits to end up in the engine oil so I have dismantled the rear gearshaft first and cleaned the components affected in Evaporust. Photo taken before cleaning the crankcase.

When re-assembling the gear shaft I checked where parts 250 & 249 fitted - I was begining to think the parts manual was wrong as I just could not get them to fit together in situ despite many attempts. I checked my photos taken when dismantling - yes the parts manual is correct - one last try & it fitted perfectly!

I have no idea why my previous attempts failed !!

Still waiting for the weather to warm up a bit - had a suspicious mole thingy removed from my side last week following a routine Dermatology 6 month check up -don't want to pull the sutures before they are removed next week.

We've just had a weekend break at Eye Kettleby for a relaxed view of the wind & lashing rain - great timing again - now I remember why we used to go abroad.

If the forecast is true a heatwave is on it's way - I just need to get my finger out and Plastigauge the big ends so I can start putting the engine back together soon. I will be glad to see the crankcase halves bolted back  together - hopefully all buttoned up by the end of June.

At least you are making progress Ted.
Maybe do some light jobs whilst you recover, the sort of jobs that creep up on you as you are putting the bike back together like cleaning the wiring loom (stick it in the dishwasher, works a treat) and cleaning anything plastic and rubber like the half rear guard, all the grommets etc. All easy sitting at the table stuff and nice to get out of the way before assembly begins.

Good idea Dave - I have started with clearing the bike lift of all tools put back where they should be then I'm going to clean the half rear guard.

Weather is nice so I could not pass up the chance for a bit more assembly - crank is in place with new seals on either side.

Primary drive rubbers fitted to centre of unit with a cable tie holding them in position.

All pushed easily into place a slight tightening of the cable tie  - then released cable tie and last few mm pushed in easily by hand!

Lower casing now has bearing back in place with lower primary chain guard fitted.

Used some Loctite on the cam chain tensioner bolts as the threads seemed less than perfect - they were not stripped but have clearly been out before- shame they don't use a locking tab on the bolts or a star washer.

Primary drive hub/unit is in place on the chain - I plan to fit the bottom case without Hondabond probably tomorrow as a dry run to see if there are any issues in putting in the drive shaft or anything falling off as you do it!

I'm thinking of getting a friend to help me with the fastening up of the crankcase - especially the main 10 crankcase bolts - that way I can ensure the primary drive shaft is in the right place. He is also 50 years younger with some modern equipment to speed things up with his fancy tools.

Crankcase halves bolted together with novelty cam chain holder to stop any accidental jamming - photo taken just before I had to separate it again.

Now that the slight high spot / bind on No: 2 conrod has been sorted I am awaiting a second opinion from my BiL tomorrow. On re-assembly  I will try to use less Hondabond - I found it difficult to spread thinly due to its viscosity but NJ has given me a tip on the dark art of thin film application.

I use the end of my finger tip and just dab it on Ted.

First time around I put on what I thought was a thin layer straight out of the tube onto the crakkcase  in 1" blobs then with my surgical gloves tried to make it spread along the mating surfaces then repeat with another 1" blob - good coverage but it was difficult to persuade it to go on thinly. I found it impossible to squeeze out of the end of the nozzle as there was no key to wind the tube up -  I ended up cutting the nozzle off a bit further up just to get it out of the tube. It was much thicker than your normal silicone sealant and very viscous too.  When I dismantled it there was far too much Hondabond on the inside edges for my liking. In an odd way having to take it apart again has had unforseen benefits. Shame its not easier to spread - next time I will squeeze it onto my finger tip then try and smear it on as thin as possible. I did wonder if the tube was old stock.

Forgive my ignorance but is a standard m6 ht set screw just the one thread type or is it automatically coarse due to being relatively small?

I find it odd that there is not a washer of any kind used on them.

Standard" is m6x1mm pitch, there is a "fine" thread ut you would not usethat in alluminium.
A washer is not needed in every case, thet are there to even the load pressure. In this case i think Hondaused threadlock on the bolts but even then ihave seen them back out, usualy when the pivot is siezed which could put excess vibration into the bolts.

Engineers are busy so Helicoils still not done yet -  yesterday took the CC bolts to be zinc plated locally as I'm not sure I could justify the cost of the Gateros Kit - might revisit that decision no doubt.
Cost me £30 for all 27 bolts & a coupe of clips - other platers seemed to have a £45 minimum charge locally.

Spent an hour or so tinkering with one of my spare engines (Pops old unit) as it was leaking oil from the sump area. Fitted a spare sump with a new gasket and all is now leak free -oil down the bores to start the freeing up process. I will try turning the engine upside down for a few minutes soon to try get some nice clean oil around the camshaft in the hope of helping preserve the status quo so as to speak as it will be 2022 before I strip it down fully.

Wendy is starting to think I have no life outside my 400/4,computer & garage. I have no idea where she is coming from  tee hee.

It's just the way the chain has laid to one side when the primary gear is not in place.

I could be wrong but I don't think the cam chain would sit central as it does if it was the other way round.

Good to see you confirm my photo is correct - the chain without the primary drive attached lies  between two gears so it looks odd if it drops to one side. Having looked again there is no way you could fit the crank the wrong way around as the cam chain would not fit in the block slot. I also know which side the points plate is fitted (No 4 cyl on the RHS of the bike) so no worries.

It might sound daft but I mark the upper crank case with a number 1 & 4 at the ends on the outside of the case lips so in my head I know I am numbering the cylinders correctly when the upper crank case is inverted.

I've contacted DS - they are posting all but a few parts out to me (including the tensioner clips) to arrive on Friday with the remainder being sent at a later date. I was slightly annoyed that the wanted an extra  £3.54  postage to split the order. A bit mean spirited I thought as I have spent around £1100 with them in the last 10 months - business is business I guess.

Hi, Ted. All I was saying was that the primary chain in your photo was out of alignment. It’s not perpendicular with the crank. I’m sure there is a good reason for that? And yes of course you can’t have the crank the wrong way round. Nice build progress by the way…I’ve learned lots.

It's Red Line Synthetic assembly lube 12oz bottle cost about £20 last year on e-bay. If I was being critical it's a bit thinner than I imagined  it would be.

Enough to last me a lifetime!

Probably depends on who you get to talk to. I made an order on Friday and then added an inlet valve on Monday which was offered free of postage if the other parts were already picked. First package arrived Tuesday and the valve arrived with free post yesterday. Now I've concluded I need 2 tensioner dampers, doh.

Build looking great Ted, good luck with the rest of the engine build.

Whilst waiting for DS delivery decided to strip & re-paint the front steering column - the Rustoleum paint has amazing cover almost too much!

In the photo the underside has been painted just about to paint the top side.

For the environmentalists note the re-purposed bog roll tubes & recyclable spray booth.

Thanks Phil but I've had to split the crankcase halves this morning as the lateral travel on the mainshaft is worrying me (see my other post) all was correctly assembled but I need to address the movement issue that I have now measured as 1.016 mm of what is effectively end float between the bearings.

Still in thinking mode about the gearbox end float so fastening the crankcase halves up again is in pause mode.

I have been doing some frame work again.

Front forks in position & fitted front brake caliper & DS mudguard. The mudguard went in okay will not really know if it's skewiff until I fit the front wheel.
As the steering is tilted to one side and the frame is not completely level on the bike stand base any out of kilter looks are hopefully just the camera angles

A brief recap about my previous crankcase assembly fails.

Groundhog Day 1 - sticking conrod so seperated  them again.
Groundhog Day 2 - gearshaft endfloat so seperated them again.

After a fitful night sleep dreaming about a potential groundhog day 3 on the crankcase halves assembly today I went for it and assembled the cases again.
I ensured there was some Hondabond on the places where the gearbox bearings sit in the casings - ensured bearings were pushed inwards from the outside to reduce excess movement.
All bolted together like a well practiced routine - everything is hunk dorey so then came to fitting the primary gear shaft - never had any issues previously until this time when the shaft did not want to pass into the primary gear hub centre. (I'm starting to think - the new primary bearing is just making everything a bit tighter fit)

After much sweating and making no progress I decided to try to rotate the crank a little to ensure the primary chain was seated nicely on the crank end. Then as if it was all a bad dream it slotted in nicely. Spacer - second new bearing pushed in place - end circlip - end spacer & gear all fitted.

The only real casualty of my previous failures is the nice paint finish on the crankcase halves has been removed in paces when taking off the Hondabond with thinners.
I will do some masking up and get the cases re-painted before I fit the casing unit into the frame.

I will sleep soundly tonight lol

This afternoon I fitted the pistons making sure it was impossible to drop a circlip into the engine as I progressed. Trigger had numbered the positions 1,2,3 4 on the tops with his marker pen.

Fitted innermost circlip on the bench then worked my way outwards fitting number 2 & 3 pistons so that the second clip could be accessed from the ends. Then lastly fitted numbers 1 & 4 all have the letters "IN" facing the inlet side of the engine.

Finally covered up the top of the engine to keep out dust etc finally placing an inverted cardboard box in place ready for Monday when my brother will help me fit it into the frame.
Just noticed a small run in the engine paint I'll get that sorted next - turned out to be an oil drip!.

Thanks Phil I'm planning to get the cylinder block fitted early next week then I'll start stripping down the cylinder head.
I'm thinking all I need to do before I fit the block is fit the bottom gasket, cylinder O rings, block dowels then feed the pistons into the bores.
 
Not sure until I check the manual etc if there are any O rings or Doughty washer at this stage -am hoping they are between the head & the top of the block.

Really making progress now Ted, well done. 3rd time lucky with putting the cases together, guess the end float problem has gone away now or you've decided that it is normal. Only dowty washers I am aware of are 2 that go on 2 of the head bolts, I've bought some but they look too small on the outside diameter, I'll have to check.

At the moment the end float has gone - as the bike is used the Hondabond might not hold everything as it is but I'm happy to proceed.
So no Doughty washers between the cylinder block & crankcase - keep me up to speed when you find the right washers as mine are a mess.

(I have a spare engine for a reason.lol)

My brother Paul gave me a lift in with the engine base unit this morning - I had blocks of wood under the sumpless engine so when we positioned lifted it in it was by a combination of forethought and luck within a few mm of the right height. Hardest bit was getting the rear long bolt in position - thwarted for a couple of minutes by what turned out to be bubble wrap getting in the way.
Not much thread to work with on the front bolts so might have to select  thinner washers - at present there is a spring washer plus a flat washer - I'll check if both need to be there in the parts manual.

This afternoon (Tuesday 24the Aug) I fitted the gear linkage bits in the clutch case housing - it was not too fiddly in the end just hope the gears work okay.
I'm forever removing dog hairs that seem to blow in - need to use a cardboard box to cover up the engine rather than a clean(ish) old towel.

Out of interest is it possible for me to test the gear selection as the top wheel rotated as I tightened the bolt and it is now in a gear?

It would be good to know that the selection system works presumably I will have to fit the nearside cover and connect the gear shift?

You can try gear selection and put it back in neutral without putting the left hand cover on. Clamp a mole grip on the gearchange shaft and change gears with that. Don't damage the splines though. 🙂

One giant leap forward for Ted not a giant leap for most sohc members!

This afternoon I started the task of fitting pistons into the bottom of my block cylinders after a couple of decades  only fitting pistons on cars from the top end. This video was my homework the day before :- https://www.youtube.com/watch?v=YfCwpDsP_5E

For the benefit of those who have yet to start this task I'm going to verbalise my process.

1) I checked that the piston ring gaps were suitably in a staggered position on each piston & that there was oil smeared on the cylinder insides. Gasket was in place with the two locating  dowels
  one on either side.

2) I put a long socket on the mainshaft as my clutch basket is not in place so I could easily rotate the crank slightly if needed to wiggle pistons a tad.

3) I found a suitable piece of wood to support the block at the centre where the camchain runs. I ensured that the wood was tall enough to hold the block just clear of the pistons when 2 & 3
     pistons were close to the top of the stroke.

4) I carefully fitted the block over the studs lowering it until it touched the piece of wood. (see picture)

5) I fed the camchain through the block using a cable tie then secured it to the frame so the chain was reasonably taught. (used spare small dog collar on frame lol)

6) I rotated the crank so that pistons 2 & 3 were about an inch from maximum height - the idea was I would be able to pull the pistons up towards the cylinder liner/block if needed.

7) I carefully removed the block of wood - then put another block of wood that was about an inch thinner in place carefully feeding the pistons into liners 2 & 3 as I lowered the block ensuring
    pistons 1 & 4 were not trapped as I did this. The cylinder liners have a great suitable taper start to them.

8) I then made sure the top ring of piston 2 was in position at the start of the taper to the liner. I then moved to piston 3 and fed the top ring into the taper. A combination of pulling up on the
     pistons or allowing the block to move down made them go into place with no need for excessive force that could break a ring.

9) Once the first ring of pistons 2 & 3 were into the taper I squirted some thin oil onto the top of the pistons. I then repeated the above process until the second ring & finally the oil control rings
    were inside the bores. I lost count of how many times I circled the bike ramp to check everything was in place. Now I was happy that pistons 2 & 3 were in place I rotated the crank to give me
     some room / height to repeat the process for pistons 1 & 4.

10) I now had all four pistons in the liners so was able to just wobble the whole block down very carfully & evenly  making sure the liners did not touch the crankcase sides as it finally engaged
      the bottom dowels.

11) Tbh the whole process took about 40 minutes as I kept walking round to make sure each ring was in place. I found that I could not just use my fingers to fit the rings for the last two pistons
       as the gap and angle was a bit tight even when I rotated the crank to raise the block a little. I used a 4" offcut of 25mm Speedfit pipe to assist my finger nails for the last two pistons.

I had no issues with the front down tube getting in the way - periodically the wooden block would fall out so I would move it to the other side.

As the head gasket  was not leaking before I dismantled the engine  plus I have been careful to not damage the contact surfaces I can't see the need - I will carefully remove any old bits of gasket so am hoping a skim is not required.

Probably worth getting it checked against  suitable flat device  - I plan to ask my friend who is a mobile mechanic how they check alloy heads at work - not sure what the protocols are on the sohc site.

As I am waiting for parts from DS I decided to make the earth connections for my indicator lamps & fit the front indicator lamps - a bit boring - yes it's not the standard headlamp but decided to keep the original headlamp frame to help with stabalizing the new light. I might have to shorten one of the new earth leads. The headlamp bolt spacers are a temporary mock up to see how it all fits - ideas stolen from Allan Kelly.

The eagle eyed members will have noted I have a new garage door as my old one was worn out after 31 years.

I forgot to take a photo of the top of the block with the four dowels, seals, oil restrictors etc in place - well covered in the manual & the video (https://www.youtube.com/watch?v=YfCwpDsP_5E)

With the camchain tensioner blades both in place I lowered the head partway down the studs so I could feed the tensioner blades through the cylinder head tunnel/slot. The camchain that had a long cable tie attached was fed through the gap between the two blades. Head went down engaging easily with the dowels. Fitted the copper washers & domed nuts in place with the doughty washers, correct nuts fitted to the studs in the spark plug access hole. Fitted rear tensioner blade top cap in place having fitted new plastic clip earlier - finger tightened , front blade in slot on head.
Torqued down cylinder head in sequence as per manual working in stages of 8, 12, 16 then finally 19.6 Nm - lost count of how many circuits of the bike stand I walked during this process. Finally torqued down the two bolts on the cam tensioner top cap. Spark plugs loosly back into head to keep out muck.

I have fitted the tensioner top cap the wrong way around in the picture so had to change it,

Whilst I had the energy left decided to fit the camshaft in position - once I had reversed the top retaining cap for the tensioner arm I could get the chain on the top sprocket.lol
It took me a few nano seconds to spot my error.

Timing mark on TDC for cylinders 1 & 4 I used the big nut on the primary drive gear to rotate the engine, threaded the camshaft carefully into position cutting off the cable tie slipping the chain onto the sprocket until the timing marks lined up horizontally.

I rotated the camshaft to align with the sprocket holes & bolted it in position with the large disc plate in place. Now I am either very lucky that the holes lined up first time if it's an offset lug on the camshaft or I need to check that it on compression for number 1 cylinder on the cam lobes?

I have checked the lobes on the camshaft and they are both pointing down on number one cylinder so by pure chance I think I have the sprockets bolted on in the right position on the camshaft.

That's my lot for today I have run out of energy!

Is that because the camshaft rotates at half crank speed meaning  1 & 4 spark at the same time so unlike a car with a distibuter you can't get the ignition timing 180 deg out?

Still waiting for some small items from DS so I've started the boring stuff - dismantled both of the front footrests - cleaned, Evaporust & painted the RH side first.
Replaced bolts with SS ones, used cordless impact driver to remove the two bolts throught the grip plate as they were tight. Cleaned the rubber part using soap & warm water - dried them - then used Auto Glym Bumper & trim gel to restore the blackness - it's a clear gel.

You can buy the pivot pins in stainless as well Ted, might as well complete the look. Plus it stops them rusting.

Do you have a source for the correct SS front foot rest pivot pins please?

My loom was a mess so I've a bought a new one - I've started to realise that there are other bits of smaller looms like the fuse box & alternator mini looms to clean up.

Does the dishwasher trick clean up the brass terminals or are they all in need of a wire brushing with a small brass suede shoe brush?

Another good reason to never ride in the rain - good shout Oddjob - they look well tidy!

As it lashes down in rain here in Derby I am reminded of my many trips from Derby to Chester in 1967/8 on my Honda 250 Dream in all weathers as a teenager- I could not afford leathers as a student (I dreamt of a Belstaff jacket) so I wore fully water proof rubber  leggings, hiking boots, an Anorak and for the winter some big leather Gauntlets - I did have a decent helmet.

I've looked at my rear pegs and there is a fair clearance on either side  - when the footrest is down yes there is some side movement even when painted - when the footrest is up they are pretty much solid as the tension on the compressed rubber feet hold them firm. In situ they look pretty much as they should - plus  horizontal when down. The Clevis pins needed a very slight tap with small rubber hammer to fit - the pegs rotate on the clevis pin as its held in quite tightly by the washer & split pin.

Post by: McCabe-Thiele (Ted) on October 11, 2021, 04:37:18 PM
I'm thinking that it's only the paint making the clevis pin sit tight Ted, as soon as that wears down you may find they are loose. Mine, minus all the paint are very loose and I've followed old Honda before and watched the entire rear footrest vibrate and rattle around even on smooth roads. Just a thought, I'll keep you updated on how the mod goes in case yours start to rattle around.

I guess you could fit a wavy washer(s) between the bracket & the footrest?

Post by: McCabe-Thiele (Ted) on October 16, 2021, 09:14:54 PM
My solution has arrived and it works very well Ted, TBH it's so simple I'm sure I'm not the first to do it. The original pins were 6mm and the nearest imperial size is 1/4" which is around 6.3mm, so I sourced some 1/4" stainless clevis pins, measured and found 1 1/2" would be long enough and ordered those. https://www.ebay.co.uk/itm/323993236763?var=513035785363

The pins fitted the outer part of the footrest perfectly, so that shows how wide they'd gone, the inner ones it wouldn't go down, almost but not quite, so ordered a new 1/4" drill bit and that's fixed that. The length is better as well, very slightly too long but that allows a washer to go behind the head so stops that wearing the metal of the footrest bracket as it rotates, the 6mm ones wouldn't allow this. If you haven't compressed the outer bracket like I did it would also allow a washer or maybe 2 to go between the footrest and the bracket and still fit.

Looking to see if I can find some 21/64" ones for the front now, might have some specially made, can't be doing with sloppy footrests. Or maybe I'll try some 3/8" pins.

I'll never carry a pillion so for me its academic just don't like to see frame brackets with nothing attached.

At the moment the cooler weather is slowing me down - as I expected as winter approaches- my stable Angina condition can trip in unexpectedly when the air is cold in the mornings - I get plenty of warning warning signs so it's manageable but if I'm not careful the Black Dog then descends and sapps my energy - not helped by recent poor sleep patterns.

I'm pleased with my progress - I can do some jobs like wheel bearings in my heated garage annexe - I'm looking at heating my workspace if needs must as it gets colder outside.

Thats looking great Ted, well done mate.

If anyone wants a cheap light trick, second  hand bathroom halogen recess spots. I bought 4, hook em up in a chain through an off cut of timber and hang on big cable ties in the eaves. The cable ties grip the timber so you can swivel it from about 8:30 to the left and 3:30 to the right and you can slide it along the thin latt you hang it from over the bench. Cost me a tenner all in and is super bright as well as warming yer hands in the colder months. Moisture resistant and just on some flex to a plug. spot on.(https://uploads.tapatalk-cdn.com/20211022/acce0f9b817d78943feb4611b7393c49.jpg)

I switched to high frequency LED's just before lock down as my old flourescent ones (bought used in 1990) were an odd size & tubes no longer made - I get mild SAD so there I've heard there are proper lights that can help.

That's a neat idea those bulbs chuck out some heat it's jogged my memory - I have in my loft a pair of Halogen flood lights on a tripod adjustable stand that I used to use when decorating  (circa1995) they would work & are fully adjustable.

I've just found them and they are 500W each with a super beam of heat!!

There are grills over the lamps to stop you burning yourself - when I used to use them to see where I was painting whilst the ceiling lights were down I wore shorts & T shirt in the summer they were that dam hot. I had to have a new garage door this summer so I've a fully insulated sectional one that is pretty draft proof - my ceiling is boarded - was going to Kingspan it but spent the money on the bike instead.

Oh, yes. Nearly there Ted.

I have to agree  with you it's starting to look like a bike again - once my back wheel is in I'm going to start fitting the wiring loom - that will be fun - electrics can go really well or just turn into a series of things just not working right.

I'll have to brush up on my AVO skills first as I usually just rely on voltage readings for most things - also I have  a tendency to forget that an earth connection on the Honda is going to mean it's a negative ground unlike modern cars that are positive earth. Once I have worked out the colour of a ground wire is usually green it should start to make sense - unlike most cars where they are brown. I can easily get confused - I like block connectors that are Male or female with offsets to stop you plugging the wrong ones in.

I'm not sure now what colour the tank & side panels will be  - originally it was going to be a metallic navy blue or silver with chain mail hydroponic transfer or whatever you call the floating transfer process.

My original plan was always fluid - the gold wheels was a pipe dream that became a reality - my BiL has gold wheels on his Ducati and Ive seen some on a meembers Moto Morini  (teenybop1) plus I love Gold Wheels. I even talked Wendy into some on her Merc.(below) Edit: Since that picture was taken the centre caps are gold background not silver on one side to see if it looks better.

I'll wait until everything else is done and the engine has been running  before I decide on the paintwork - might use the bike next summer and do a Phase 2 next winter.

I thought the gold rims looked really good, and good compliment to the blue used as well. As pointed out already, it's yours to do as you wish with.

Very nice car there Mrs Ted has  :D the gold and blue evokes a period when gold wheels were more prevalent and design influences more resolved. They seem to be all about gargoyle (cars and bikes) and massive graphics currently.  Even in your own mind you may not be certain exactly if it's heading where you thought until finished sometimes.

Seems like the build is certainly gathering pace, the bit as it reaches more bike than bits always feels good. I like watching your progress Ted, thanks for the effort in documenting and posting.

Nice Ducati you have there - my BiL discovered when he had some recent paintwork done that the mirror mounts on the front headlamp fairing section had been filled in by a PO who fitted bar end mirrors amongst other changes.

My BiL only rides it to and from Mot he has severe arthritis in both hands - he is on methotrexate and recently had Gold injections into his worst fingers. He used to work in acid dipping of glass - the acids have leached calcium from his bones.

I went out on it for the last time yesterday,shes going to a new home as I cant ride it anymore either. It was bought as a giant mechano set when I had a really bad break up some ten years ago. I bought her in boxes for a grand and did it up as a mind exercise; an expensive one but a good one. A pals buying her and keeping her in the near family which is good.

I have metal rods in my wrists as a result of a bad crash as an adolescent and a work injury and at the jaunty angle with which you have to sit on it, it makes my hands numb ::) so  I find it really hard to ride for any length of time.

Happy its going to be ridden, its a hell of a bike. Its got a 916 barrels and heads so you get the spin up of the 748 but the extra oomph of the 916 making her an 853cc and rather rapid...............Kinda done with that now and I've still got the VFR if I want my eyebrows spreading so that breaks the heartache a bit ;D

This might be my last post this year on the project as the colder weather is definitely having an effect on my ability to work in the garage - last push today to assemble the rear hub and fit the wheel.

I have put the thicker axle spacer on the right hand side so hope this is the right way round - it's as it was when I got the bike except now in SS. I am very aware that a lot of my nuts like on the rear axle will rust again as I have not had them re-plated - I might think again about a plating kit next year or just paint them for now.

New pattern gear lever arrived today -circlip has no spring left so I will need to replace it.

I got my front wheel back from Croft Engineering - The hub thread needed cleaning before I could fit the new lock ring as the first thread where it was peened over was very tight. I did not have a suitable thread file for internal threads - they made a special boss to clean it out - as it was a one off they gave me the part they had made to do the job so I have it for future use if needed.

When the front wheel is in place I will post a picture.

I've looked at my old photo before dismantling - it was like I've re-fitted it the same way - I suspect you could be right though looking at the parts manual?

Update: That might explain why the link bar looks a tad too angular - presumably when it's fitted the other way round the link bar will be straight!

I'm just a frustrated Chemical Engineer who spent four years at University on a college based thick sandwich course back in the days when the local authority gave you a grant to pay not just your fees but an allowance to pay for Digs, food, books and most importantly beer!
On my course I got to work in four different industrial placements - one was Associated Octel who made the Tetraethyl Lead in Petrol at Ellesmere Port, Laporte Industries in Stallingborough on an experimental distillation rig, Maitzena Werke GMBH in Krefeld Germany and BPB Industries. Due to the dire economic situation in the UK in 1973 when Harold Wilson was PM that was the end of my dream. I obtained an SRC grant to do my Masters Degree but returned the cheque to start work proper  - life is a very meandering stream just like some posts here.

It was Bradford a new redbrick Uni at the time 1967-71 the M1 in1967 stopped south of Sheffield.

Anyways I've fitted the gearshift the right way - will need a new circlip as the 3 point clips I have do not sit fully in the groove. When I've looked at pictures of stock 400 fours they all seem to show the right hand side pics not the left. If anyone can show me a picture of the splined lever in the correct position that would help me get it right. Too far clockwise and the bar strikes the footrest - too far anti-clockwise it can touch the casing.

I love Timothy Taylors Landlord - got pretty "happy" one lunchtime in Bristol with my mate Bob whilst our wives went shopping (we were attending a friends wedding) sadly Bob's wife died suddenly at home of Covid last year. Yvonne is the only person that I know who died from Covid - that said my circle of close friends is not huge.

Back to the rebuild:-
Yesterday I finished fitting the front wheel bearings in place with seals spacer etc - if the cold weather holds off I hope to get the front wheel fitted as soon as my little jack arrives. That will leave    me the wiring to connect up, tappets, timing,exhuast system then finally sort out the tank & side panel paintwork. Snagging lists of things to tighten, check & adjust.

I can see light at the end of the tunnel - that's why I'm slowing down perhaps as I do not want it to end?

My bike jack arrived this afternoon so whilst it was above 10 deg I have removed the front wheel,  started dismantling / cleaning the speedometer drive as the temperature dropped so will see what bits if any you can get for the unit - at the minimun I could do with the oil seal but can't see it listed  in the parts book or on the DS site.

Anyone have a source for a new speedo drive hub oil seal?

The old seal will have it marked on it Ted, I just bought 2 off eBay for the 500 drive, they may well be the same size.

I think the other seal inside the tunnel is the same as the 500/550 tacho drive.

The seal has the markings NOK AE1967E .

Seal has arrived - despite the cold weather - I fitted it this afternoon - now waiting for the large "O" ring and small cable end seal so I can assemble the whole axle,  fit the brake disc and get the wheel in place before the ice age sets in.

The last of the Supermarionation series was Thunderbirds... but his last puppet series wasy Terrahawks ... made in the 80's, it ran for only 3 series and was set, laughablu now ... in the 2020's. Used more latex hand puppets and less strings.

Loved Stingray.... but I never understood why it said 'anything can happen in the next half hour' in the opening credits...but the program wasn't half an hour long.

Not a lot of progress as I have had a nasty Virus since Christmas Eve with the green shoots of recovery appearing only in the last couple of days.

Finally fitted the front wheel - the disc seems to be binding on the new pads even though there is no fluid in the system & the piston is completely free - I suspect it's something to do with the weird long screw / spring arrangement on the pivot arm. I need to check the manual as to what to do.

By the time I had fitted the wheel and turned the bike round on the stand so the front wheel was in the clamp I was too tired to do any more today.

I'm liking the look of the wheels now they are both fitted - hopefully I can start fitting  the exhuast system next.

After much fiddling about I managed to fit the front pipes so they do not touch and are reasonably well engaged into the 4 into 1 section of the silencer.
I think I will have to remove the silencer for a final fit as there ought to be some sealant where the front pipes go into the silencer.

I used the original rear bracket in the end to use both hangers - only bolts I had that would fit the dead eyes are the allen key headed ones - as & when I'll fit proper bolts.

Tbh I'm still undecided I might leave the tank & panels and see what they look like in place before I make a final decision - at the moment I'm leaning towards the same colour as the frame - I have the RAL number so can go with that or a much darker  cobalt blue / navy blue colour.

Thanks for the feedback folks - the photographs do flatter the build of course - my phone  camera must be soft focus by default.

Thats looking fab Ted, I'm ABSOLUTELY loving the gold rims, they bring the blue out beautifully. Dont make it 'too' blue though mate. It's your bike but just saying. I always go out looking at colours in the car parks, its a great starting point as you'll know the make so you can narrow the colour chart down then once sorted, take that colour code to your painter and say what alterations you want such as brighter, darker, bit of sparkle, what ever. Saves a lot of umming and ahh-ing and trawling through colour charts.

The colour we did Chewy was a Mercedes Vito colour, they only did four or five shades of that blue that year, on that van. Once all five are in front of you it's easy to spot the one you liked and thats the code to start from. Saves loads of time and makes the process a lot less faff.

Go for a mooch round the supermarket car park, next time your there and see what floats yer boat and yer away...

Top build though Ted, loving it to bits, well done.

As posted elsewhere today I bled the front brakes using a syringe to pump it into the front caliper bleed nipple using Silicone brake fluid in a clean system - it went like a dream with a decent solid lever.

Next task is the valve clearances - I could do with it being just a tad warmer as I want to do all 8 in one warm session. I have the feeler strip so next I'll read up on the sequence/order in the manual.

Tappets, all four cylinder conventional engines are the same essentially.

Turn crankshaft to T on 1+4 cylinders (1 OR 4 will now be on compression with both valves closed) set the clearance on the cylinder that's on compression with both valves closed, also 2+3 cylinders will have ONE of their valve closed so you can set those.

Now rotate the crankshaft 360 degree to T again, now the opposite of 1+4 cylinders can be set along with the two on 2+3 you didn't do the first time.

In short, with the two crankshaft position you can complete all the valves.

I just turn it to TDC on each cylinder as it closes the valves. So it's 2 more movements, so what, it's not like it's hard work.

I just turn it to TDC on each cylinder as it closes the valves. So it's 2 more movements, so what, it's not like it's hard work.

So Ken am I understanding you right  if I say when  number 1 cylinder is at TDC with the inlet valve having just closed then both inlet & exhuast can then be set on number 1 cylinder then repeat for remaining cylinders?

On the old A series BL engines I would get number 1 cylinder with the inlet valve fully open on the camshaft then there would be a corresponding (exhuast?) valve on number 4 cylinder that was fully closed. It is a long time ago it was a firing order thing.

Post by: K2-K6 on February 08, 2022, 02:10:37 PM
Likewise, along time since I've done A or B series. Chugging through distant memories seems to bring the total of 9 up. Valves numbered 1 and 2 for first cylinder etc, and so with 1 down (valve open) then adjust #8 making 9 then so on with 2 down, adjust 7 until completely done with each pair adding up to 9.

Every four cylinder is the same though (except for Yamaha R1 that has offset crankshaft like half a V8) with all of the routine however you do it as applicable across them.

NO TED,
When the exhaust closes and inlet opens on No 1 tdc(called on the rock), adjust No4, then rotate crank 1 turn to tdc again  and do No1
To save any confusion at all i then do the same with 2&3

Post by: Oddjob on February 08, 2022, 03:06:30 PM
Bryan has explained it Ted.

Get all the tappet covers off, as the mark approaches 1-4 TDC or T watch the valves on number 1 and number 4 cylinders, one of them will have both valves going down/up, the other will have them both up, the one with both up is the one to do. If you grab a tappet adjuster you can rattle the one on compression stroke, if it's number 1 (and it's a 50/50 chance of it being that) then after doing the tappets turn the crank (clockwise, always clockwise) then as 2-3 T mark comes up you do number 2 cylinder, turn again to 1-4 and do number 4 and lastly turn again to 2-3 T and do number 3 cylinder. The firing order is 1-2-4-3.

I always do the tappets with the plugs out, Bryan always says DON'T use the big nut to turn the crank with, however that is how Honda tell you to do it, if the plugs are out it's not a problem and TBH how else are you going to turn the crank, yes you can use the kickstart BUT it's a real pain and it's very imprecise especially if your doing the timing that way, you could of course remove the generator cover BUT that's a big job, usually means a new gasket and chances the electrical connectors getting disturbed, no one in the trade would do that, especially if your doing timing, you need to rock the crank and watch the points open and you can't do that with the rotor, it's on the wrong end of the crank.

Plus one on plugs out using the “big nut”.

I tend to adjust using 1thou more on the feeler gauge when nipping up. It seems to result in a nice sliding fit at the specified clearance.

Just saying what works for me.

TBH Ted, you rotate the crank once for that method. You need something to remind you which of the inner cylinder valves you can do, the other way you don't need to think what valves to do and you rotate the crank 1/2 a turn more. Seriously it's a no brainer, even in the trade we never did them like the Honda method, just not worth the bother for 1/2 a turn.

Don't over think it, just do the easiest thing.

I have now adjusted the eight valve clearances - I had forgotten what a fiddly task it is. Its about 35 years since I adjusted a set as my more recent cars have had hydraulic ones - got easier with practice. No doubt I may have to make some minor adjustments after the engine has been run.

I'm looking at minor tweaks to the wiring loom routing having made some changes on my speedometer & rev counter routes near the headlamp area. Handy having lots of photos to check against.
Currently fitting new male connectors to the small loom from the left side of the handlebars as they were all the wrong size. The PO had added some wiring in this area but what had been fitted I am not sure as some wires had been cut off to remove the item or items - possibly a DTRL or some sort of relay arrangement?

Major leaps forward on the wiring front just a few minor things to resolve like the clutch switch that was missing so need to work out where the connections go. I assume the switch is standard in the UK. Last task on the wiring will be trying to sort out the bunch in/behind the headlamp. A quart into a pint pot.

Cant remember the colours but they connect in the headlamp, gree/red is one that comes to mind.
You can use a front brake light switch from a drum braked cg125 or similar, wires are different colour but fittings same.

35360-341-000 superceded to 35360-329-003 Ted, colours are green/yellow and black. Costs £18.48 from DS.

The parts book says the 35360 number Bryan, although why Honda would produce another almost identical part is beyond me, even the wire colours look the same. Price is about the same as well, depending where you buy. In fact the proper part is cheaper at CMS. Maybe the wires are shorter on the 125 one?

Fitted 4 way connector where rear brake lamp loom connection feeds the rear brake light switch to enable power supply to my electronic ignition. Fitted an additional earth cable between battery and existing loom earthing point on regulator mounting bolt to hopefully generally improve earthing.

Painted inside of rear chain guard with Zinc Primer prior to final painting before fitting.

Front wheel collected by CWC to have the tyre issue resolved.
Chain guard now fitted as is the headlamp unit with nice new H4 LED bulb.
Cleaned out the pipes on the  Motad silencer where the front pipes fit to make fitting a bit easier when the wheel is back.

Warm spell will mean I can do some other bits and bobs before my wheel is returned on Friday. I feel confident that the bike should be a runner for my birthday in early May (fingers crossed).

I am keeping the tank & side panels as they are for the summer of 2022 - then looking at the possibility of re-paint & change of exhuast system for Phase2 in 2022/23.

I am assuming of course that the big guy in the sky continues to look down at me favourably for a few more years yet.

Wheel now back from CWS with tyre fitted the right way round - assembled front axle parts torqued up spindle, speedometer cable in place etc.
Wheel fitted clamps torqued up, starter cable connected ready for cranking over having turned it with the kickstart by hand to check everything feels right rotationwise.
Adjusted front brake caliper as per manual.

Exhuast system going back on probably Monday or Tuesday depending on weather & household obligations.lol

I do have a spare engine so I might strip that down and rebuild it (when not fishing) - not sure tbh. Bonus would be I have a better idea of the costs involved plus the confidence to do the job.

Then there might be the Phase 2 option if I want to pour more money into the existing project and tidy up more areas.

Iastly I have our Mercedes R129 that we have had for 19 years that I could tinker with if I was desperate for things to do.

Nice warm day again so fitted he exhuast system with silicone sealant where front pipes enter the silencer.
Just as I thought I knew what I was doing I realised I had not fitted the front pipe clamp over the pipe after getting number 3 pipe into the silencer. Struggled to get it out of the silencer again  - re-fitted - did not make the same mistake with No 4 front pipe.

With spark piugs out I cranked engine over with starter until oil light went out - it took a little longer to go out than expected but once it went out it was quick to go out again pretty much straight away on the button.

Looks like it might be Friday before I can do the ignition timing then get the petrol tank fitted - inching  achingly closer!

There was a time I would have worked until midnight to get the bike running today - Wendy is on Holiday so I need to keep a perspective and be patient its been over 19 months . This morning I took my fishing tackle out of the garage loft ready for another summer distraction.

Getting there Ted. The weather has been great for motivation recently, let's hope it's better than the forecast over the next few days, 8 degrees is going to feel bloody cold. As a matter of interest, where did you get the idea for putting silcone sealant in the exhaust joint? I have re-used the old gasket as it was in good nick but haven't checked yet to see if it has made a full seal.

It was mentioned on this site a friend gave me a part used tube of high temperature silicone sealant it was Grey in colour.
I was going to use normal clear silicone its just on the downpipe to silencer joint as the Motad system has no gasket.

The product I have used made by Elring of Germany  Dirko HT Silicone based sealant -  temperature range -60 C to +315 C just a smear like Hondabond when inserting the pipes - fairly slow drying as well so it does not go off whilst fitting the last pipe in place.

Timing has finally been done thanks for your help K2-K6 via PM plus a U-tube video. Most of the pipework for drains etc now in place. I'm in the process of re-checking the cam timing for peace of mind before I fit the petrol tank & try to start her up. I've had a cough in the night that I've not shaken off so done a lateral flow test. Test negative but playing safe i'll stay indoors today.

Pretty sure I have another mini  groundhog day on my hands, I'm still unwell from Man Flu Bug but have done as Ken suggested to check the valve timing and it does not look quite right.  I suspect I have messed up the valve timing by using the 1-4 advance mark instead of "T" when I fitted the chain.

I'm not going to remove the cam cover until I am feeling much better so I will just go through some mental processes for my plan of action. If possible I would like to avoid having to take the carbs off if it can be avoided.

It looks as though I can just remove the horn, coils, various cables for ease of access then remove the top vent cover. I'm minded to loosen all the tappets before I remove the rocker cover bolts in the correct order to take the rocker  loads off the camshaft.

I guess I will be able to then align the T mark and see the horizontal camshaft marks - care not to drop the sprocket bolts into the engine by plugging  up the routes with a nice clean tea towel or similar.

Any tips welcome please do not say the carbs have to come off I did such a neat job of fitting the air boxes through the rear of the frame with the wheel & mudguard out.

Thanks Ken that's a relief of sorts.

Still beating myself up for such a rookie error my excuse is that cars have slightly different markings with ephasis on TDC with various timing advance marks in degrees - stupid-stupid-stupid me.

The white shoots of Covid recovery have started. Yesterday whilst cleaning the underside of the petrol tank I found yellow edges. The bike was either originally yellow or its had a different tank fitted.
Waiting for a couple of vent pipes from DS before I can fit the tank. It will be fiddly fitting the pipes with the air box in place but pretty sure I can do it with my long fingers!

After some over the weekend procrastination I decided today is the day to fire her up.

She took a few cranks followed by some popping & banging then she fired into life on all four cylinders  I am suitably estatic!

This phase of the rebuild is hopefully now finished just have a few things to tighten up on the front brakes and she might even get a run around the block in the next 24 hours!

Just one small observation, does that rear brake lever need moving round a few degrees closer to 90 and the rod pushed through a little more.Apologies, but I’m quite fussy about things like that.😌

Yes the rod is not as far down on the thread as needed. I've actually moved it twice and ended up where it is. The brake shoes are new and I'm pretty sure they will bed in quite quickly as with the thread proud of the bolt you can still rotate the wheel with some effort.

I was trying to maximise the leverage.

For now I have a set of 400 carbs that need cleaning with the steel bits needing some re-plating. That and fishing should keep me quiet for a bit plus a petrol tank that needs stripping & the dents taking out prior to painting. Tbh I keep on looking at other 400s for sale but they seem overpriced.

I need to get some miles on the bike to run it in & gain confidence on its reliability - also could do with green P plates on the back to refresh my riding ability as at present my adrenaline level are too high in anticipation of a ride yet alone actually doing it.

There are so many things on my existing bike that I wish I had done better - such as having the block & head sand blasted for a better paint finish surface. (I did have quite a few things going on healthwise during 2020 not to mention Covid situation) 
I did not bake the painting on the main engine casings or head as I was fearful of heat distortion.

I'm still thinking of buying a Gateros Plating kit - there seem to be a lot of options on their website plus I might need to install a cooker hood extractor for safety. There is probably a post somewhere on here about setting it all up etc. It might not be cost effective but must be a great feeling doing it yourself if it goes right.

The bike looks fabulous Ted, great credit to all your time attention and hard work in completing.

Normally I favour black frames (unless it's Italian) but that deep blue coupled with the gold rims looks particularly good now photographed assembled and in daylight, and nicely different.

At least we've all kept you out of trouble for a while  ;D it'll be good to see you both out and about at Crich. Looks like some nice conditions to get out and try bike and new riding gear too.

Just a brief update on my original Project thread - firstly I have realised that what I thought was a bit of a thrown together bike was actually pretty much complete & in good condition for one that has had so many previous owners (10 iirc).

When my 500 is completed sometime around May/June  2024 my plan is to re-visit a few areas on the 400 that I either did not touch or that I will change provided the 500 runs okay.

The front forks were fitted with new seals by the PO at an unknown date.   I will drain the oil to see what state it is in as I suspect it was done a while back.  I intend to fit a different front headlamp - most probably the 500 unit that has a standard size lamp unit.

I was planning to sell the 400 when the 500 was finished to fund the next build - time will tell if I have the energy for that. More importantly I want next year to be a warm dry summer so I can have some trips down memory lane on two wheels.

You may find Ted that the 500 headlight won't fit on the 400 due to it's shape, you may need a 550 bowl instead and even that may not fit. The 500 bowl won't fit on the 550 for example due to the position of the ignition switch.

I'm sure you are correct Ken a 500 bowl will not fit in a standard 400 headlamp bracket mine is a bit of a mongrel arrangement as the original headlamp unit was scrap - badly damaged rim, rotted reflector & split bowl.

I retained the old 400 headlamp bracket to act as a brace for my current headlamp mounting arrangement. Presently it  is mounted on a pair of fork alloy  brackets that pushes the new mounting point forward quite a bit & lower by around 3/4" so plenty of room. I have checked it against my original black 500 bowl. All I will need to do is alter the spacers I fitted on the side mounting bolts. Undecided if I will use a chromed plastic headlamp bowl or the black one I have.

With the mild weather as I'm stuck on the 500 until the wheels come back from CWS I've now replaced the fork oil & changed the headlamp bowl to the 500 type as it takes a standard 7" headlamp unit so lots of options for a decent lamp unit - for now it's a Land Rover Defender type.

Fork fluid changed will not know until I ride it in the spring if there is any difference but it should be a tad firmer as the right fork tube had very little oil in it.

I willl bob a photo of the new headlamp look on here later today or tomorrow.

For now it's the full LED unit with Halo front sidelamp (5W) as a DTRL not a higher powered version unit that are available as an option mine is 60W/90W output 2400/3000 LM.

Yes the sink was put in about 10 years after all the mains sockets so the one above the sink is a risk but the garage has a consumer unit with RCB's etc.
