CB750 / Re: Winter storage
« on: October 03, 2022, 10:41:40 AM »
Hello all,
I've been using ASPEN pure petrol whilst the bike is stored so I can start it up periodically and keep the oily bits inside the engine lubricated.
There is no Ethanol in this and will last a couple of years in the fuel system without going 'off' and not eating pipes and alloy bits.
Its available from Garden Centres in the main as you can keep it in your lawnmower, strimmer or whatever - not cheap though = £25 for 5 litres.
See;

CB750 / Crap and more crap
« on: July 13, 2022, 09:34:54 PM »
This one had me fooled (again) – pattern parts do my head in.
I’d nadgered the hex head on the the bowl of the fuel tap, then the screws got chewed up and it was really manky anyway. So ordered up a pattern replacement from Dave Silver.
This turned up and it looked OK but the engraved plate had ‘reserve’ at the front position and ‘stop’ at the rear – totally opposite to every Honda I’d ridden since 1971. It was always easy to remember as Honda has ‘Reserve’ and ‘Rear’ - both start with an ‘R’ - dead simple.
So, on went the nice new shiny tap and the bike would not start – no fuel it seemed; bone dry plugs. On taking the tap apart it turned out that the rear position was reserve after all so it’s the engraved plate was wrong. Just crap .
Anyhow, once I’d got the bile running again I then had to leave it for the past 5 weeks due to pressure from my job; came back to it again and the damn thing would not start – bone dry plugs again. Ahh what now !
Took the fuel tap apart and it was full of what looked like a small quantity of sand which was preventing fuel flow. This is E10 at its worst. Never again – more crap. Just how much crap do we have to put up with??
So splashed in a few litres of ASPEN pure petrol (£25 for 5 litres) and it fired right up. If I leave the bike again for an extended period, I will always fill it with E5 or Aspen.
This bike has fought me every step of the way for 5 years and I am that close to riding it. Although at 68 years old it seems am lot heavier than the one I had in 1988.
Will report back if I survive the first ride out.
Keep safe.

CB750 / Re: No Spark
« on: May 11, 2022, 08:12:17 PM »
I've got the same problem; the spindle and nut scribes an oval as the crank is spinning. You can set the timing OK but it plays havoc with the points gap.
As you say its caused by monkeys turning over the engine with the plugs still in: the compression proves too much at tdc and the spindle bends.
I had a look at a replacement but none seem to be available. From the parts diagram it looks as it just screws into the end of the crank.
I also thought about removing it and getting it straightened by an engineering shop but then had nightmares about it snapping off on removal which would probably necessitate a full strip down to get at the crank.
Consequently I will probably go for the Boyer system too. Can you please give some feedback on ease of fitment and what effect it has on the running?
Best regards
Phil

CB750 / Re: The pipes are here....!
« on: April 27, 2022, 08:24:36 PM »
Four pipes (not candles)
I’m edging towards completion of the 750 K2; it’s taken months (getting worked to death by my employer) to get around to fitting the £1300 worth of Dave Silver 4-4 system. But now they are on it looks the D-Bs.
XX rear view [ Guests cannot view attachments ]
Bit disappointed to see that no2 pipe doesn’t quite match the route of that for no3 – it is slightly misaligned and closer to the oil filter. After 5 years, I’m now past caring and it was never going to be a concours bike anyway.
XX looking down pipes [ Guests cannot view attachments ] [
It is for me a blast from the past from when I drooled over the picture on the rear cover of the 1970 Honda brochure which featured a cool guy bumbling along the leafy lanes on a candy red K0 or K1. With my 50cc C100 step-through parked outside my parents looking at this I just dreamed the Honda Dream – the advertising is dead right
XX the pictureattachimg=3]
The ‘tins’ are back from the painters. You may remember I did the candy red out of aerosols; came out a bit darker than I would like and a bit scrappy in places. But it’s amazing what looks like a 2mm thick coating of 2K laquer will do; covers up all your sins and it all looks terrific.

Its running now, just have to sort the carbs and I’ll be on the road soon (said that before…..).
Cheers my dears.

Re painting engine with VHT paint
Don’t make the mistake I did. I had the engine out of the frame to replace the head gasket and thought I’d spray the crankcases and upper part of the engine with a VHT silver paint. I though the heat from the engine would be enough to cure the paint. WRONG !!
It works OK on the barrels and the cylinder head which get nice and toasty but not hot enough on the crankcases. Consequently, any drop of petrol from the carbs results in the paint falling off. Looks a bit messy now.
The only way is to spray them and then cure in the oven.
When I restored a CB750 K2 back in 1990 or thereabouts, I sprayed the crankcases in Ford Cortina Silver Mist and it looked good, had a bit of shine and most importantly stayed on. Wish I'd done that this time round.

I just have to sort the carbs as one is seriously rich; stick on the DS 4-4 pipe set (sold the old 4-2 on ebay for £100), stick on the tank, a splosh of petrol and should be good to go. Only taken 5 years !

Hello Everybody,
This is an old post which as you can see is titled 'Bank Holiday rattlecan' as I started this on May 31st last year - that's how long stuff takes when you've got a job like mine.
Having applied (badly) the candy apple red via a rattle can i then tried to do the same with spraying on 2K lacquer; made a mess of it and so handed it over to my local body shop who did this for £100.
[ Guests cannot view attachments ]
The lacquer looks about 1mm thick and the shine literally deflects any attention away from the flaws in the candy paint. I'm really happy with it.
Total cost so far about £320. Should have handed it to a pro in the first place - would have been quicker and maybe cheaper.

Member 4 Sales / 4 into 2 exhaust for sale – suit CB750
« on: February 07, 2022, 10:55:03 AM »
Hello all.
After re-mortgaging my house I bought one of the few sets of 4 into 4 pipes from DSS. This leaves me with the 4 into 2 exhaust which I’ve just removed and although a looking a little used with a couple of scratches, dings and thin chrome, they are too good to throw in the skip.
If you PM me I can send a video of what they sound like; a little unusual as pipes 1 and 4 end up in one silencer and 2 and 3 in another – normally it seems 1 & 2 then 3 & 4 are linked together. This leads to some crossovers underneath the engine but it all fits together well and I’ve labelled everything so should be a fairly easy job.
I should say that they are rather loud; they look like they have baffles but only very ineffective ones (the end cones are removable if you wanted to stuff something in there). Bit loud for me at my age (and the neighbours) but would have loved these in the 70s. Reminds me of the megaphones I had on my CB250K2 after the original pipes rotted out – an anti-social blast through the Blackwall Tunnel was something that sticks in my memory and probably shouldn’t.
So, there they are: too good to chuck out but will suit someone who is building a special. Use them as they are or paint them up or wrap the downpipes in heat resistant tape?
Looking for £40 plus postage (7 kilos costs about £20 2nd class). Or collect from Cheltenham, Glos.

CB750 / Shortening my centre-stand (hernia avoidance)
« on: December 07, 2021, 04:52:52 PM »
Just picking up on a previous post: I’ve had a grumble on here before as I find my CB750 hard to get on the centre-stand – the bike weighs in at a quarter of a ton and my 67 year old muscles just can’t pull it up & back. I didn’t have much difficulty back in 1988; I was a lot younger then but I don’t remember the rear wheel being so high off the ground, as it is now, when its finally on the stand. Its over 5cm.
The 750 K2 DK Special I bought came from the USA and the previous owner had removed the centre-stand in the interests of weight saving to give that extra 0.25 mph. So, I bought one off ebay and fitted it thinking they must all be the same. Wrong.
Looking at parts lists there are several different numbers and the one have is meant for a 750 with longer shocks or a bigger rear tyre – F1, Hondamatic, who knows.
Anyway, its too flippin’ long and I’ve decided to shorten it.
Using the skills acquired from my 1969 ‘O’ level in Technical Drawing, I drew a scaled plan which revealed that if I chopped out 3cm on each leg it would end up with the rear wheel just clear of the ground by a couple of mm. So less of a ‘lift’ for me.
Using my other 1969 ‘O’ level in metalwork, I set to with the angle grinder chopping out the required amount and then finding some steel tubing to act as ‘slugs’ to strengthen the points where they were to be rewelded.
I found an old worn wishbone pivot tube from my long gone Triumph TR3A which I’d kept, chopped off the case hardened ends and got a friendly local garage who restore pre-war Austins to turn them down to the required o.s. diameter so they fit within each tube of the centre-stand.
Holes have been drilled into the separated pieces of the stand so that the ‘slugs’ may be plug welded through them to increase the strength of the joints.
UPDATE
After about 12 yards of welding wire: it’s now all welded up and then stand is back on the bike; no cracks or bending and it hasn’t fallen over. It’s now far easier for 67 year old me to pull it back and get it on the stand. I know how you lot like a few pics….

Misc / Open / Re: shed heating
« on: December 05, 2021, 09:17:55 PM »
I speak from bitter experience on the subject of condensation, the formation of mold and chrome decaying before your very eyes and the strange feeling of depression all this brings.
It’s all to do with airflow and keeping the inside air temperature close to that outside. If there’s a big difference, and by opening a door and the two air masses meet, there will be a formation of condensation.
I had one of those Compton garages once, made from pre-fab concrete panels; these just didn’t ‘breathe’ and help equalize the two temperatures. So, at about 11.00 in the morning on a bright spring sunny day, the air temperature had risen but that in the garage was pretty much as it was during the cold night. On several occasions, I would open the up-and-over door, the warm air would rush in, meet the cold air and believe me a cloud would form momentarily.
Now I have a garage constructed from breeze block and brick; this allows the garage to breathe. A vent in the window is key and I no longer have to bother with a dehumidifier. If I go out to work in there, I just shut the window, turn on the heater – a 5kw job from Machine Mart. And when I leave, it’s heater off and open the vent/window again. It doesn’t matter how cold it gets in there as long as the temp matches that outside.
So to me the key is always ventilation and keeping the temperatures as equal as possible.

Centre-stand; what I’ll be doing this weekend
Its coincidence this thread has popped up as I’m just about to modify my centre-stand on my K2.
I’ve had a grumble on here before as I find my CB750 hard to get on the centre-stand – the bike weighs in at a quarter of a ton and my 67 year old muscles just can’t pull it up & back.

Holes have been drilled into the separated pieces of the stand so that the ‘slugs’ may be plug welded through them to increase the strength of the joints.
The storm due down here tomorrow might interrupt proceedings, like if the garage roof flies off, the trampoline ends up next door, but I aim to start the welding, paint it and fit it to the bike and see if it works i.e. the bike doesn’t fall over.
Will report back.

CB750 / Re: Newbie Here
« on: October 10, 2021, 10:52:25 AM »
OOOOhhh! TRs….
Glad to see so much enthusiasm for TR Sports Cars here. At the risk of losing the thread on CBs…
In 1990, I bought a US import TR3A; advertised as a California car but after I got it home turned out it came from Ohio where it rains more than Manchester. Restored it (not very well), changed it to RHD and myself, my new wife and the Cocker Spaniel used it for a good while travelling around the UK and France. Good fun apart from the vague steering, rubbish brakes and side-screen windows that fell out on the motorway; usually when it was raining.
[ Guests cannot view attachments ]
As the wife didn’t like bikes (still doesn’t) my restored CB750 K2, two C72s, CD175 sloper, C102 (Honda 50 with an electric start) had to go, so were all sold to make way in my single garage for the TR. I kept the XL250K0 though which I still have.
Next thing, life moves on; 2 daughters turn up and with no safe room in the back of the TR, it had to go and was replaced with a Morgan 4 seater. Worst car (apart from the Matra Rancho) I ever owned. A chassis like a garden gate made from angle iron, rock solid pillar suspension at the front (design unchanged from when it was invented in 1910). But with a Capri 1600GT engine in the front it went like the clappers but in a terrifying unusable way. Hated it – I didn’t get the Morgan ‘thing’ and still don’t.
[ Guests cannot view attachments ]
Got rid of that and the only 4 seater open classic I fancied was the Merc SL. A HUGE money pit but nice to drive. But the girls, who are now 20 & 22, don’t like it as they have long hair which gets tangled by being blown about by the back draught. They moan like crazy so it doesn’t really get used.
[ Guests cannot view attachments ]
I give up !! So that’s up for sale next year and maybe I’ll go back to a 2 seater; but whatever happens I’ll always keep the CB750 and XL250.

CB750 / Re: How long is yours? (Gear change lever that is)
« on: October 05, 2021, 09:15:21 AM »
Yes please Julie, if you could measure your gearlever I'd be grateful. Total length from the square bit at the rear to the furthest point on the rubber bit.
If its more than 14cm I'll know I've got the wrong one (or a deformed left foot).
Thanks in advance.

CB750 / How long is yours? (Gear change lever that is)
« on: October 04, 2021, 08:00:07 PM »
Hello Chums,
Had my first ride in 20 years on the DK/DS Special but only got about 100 yards down the road as I couldn’t get it out of first gear.
Not a problem with the gearbox you understand, but I just couldn’t get my foot (with a trainer on it) underneath the lever to move it up. Either my foot has got bigger since I last rode a K2 in 1990 or the lever is too short.
Its not the lever I remember with a round rubber on the end, this one is oval and quite stubby.
This bike has slid on its (both) sides many hundreds of yards down American roads with its previous owner and most parts have been replaced from the breaker’s yard with any old Honda bits that happen to be lying around. This I think being one of them.
Can anybody measure theirs and tell me if what I have is the correct lever? The one I have is 14cm long?
By the way, the bike is great. Goes like hell (in first).
Thanks in advance.
Phil in Cheltenham.
