Thank you Ash.

It looks like it would need a lot of work to get a decent re-chrome though.  It is quite pitted and likely to cost quite a bit I would think

I reckon I could make that work but just bead blast prime and paint would do nicely.  The bike is nice, but not going in for concourse!

How do I pay you/him?  I can do PayPal of course

Cheers, Jerry

Sorry,

Missed those replies....been busy.

Thank you for your help here.

I have just measured the dimensions on the 360. Difficult to get right by eye and a ruler, but close enough I think.

From the shock eye centre to the frame mount hole centre is about 157mm. The offset from the frame is 43mm.

The handle is of course a specific 369 part, but there may be one close enough to adapt one way or another.

I did find one in stock on eBay Germany, but at an unattractive price and of course with VAT shipping it get ridiculous.

If push comes to shove I'll fabricate something, but it wouldn't be pretty  ;D

Cheers,

Hi Folks,

My CB360 does not have a side handle for pulling the bike up to the centre stand.  One of the POs who restored and powder coated (heavily.grrr!) the frame had snapped the corroded bolt in the rear frame and couldn't be bothered with removing it before coating.  I have just managed to drill it out and am looking for a handle for it.

I'm not too fussed as to condition.  Shiny would be nice, but rusty can be painted black.  I would like to be able to raise the bike without breaking my fingers.

Cheers,

Jerry

I understand that because of the need to remove the whole rhs cover remove the kick start, foot rest and drop the brake pedal a bit, the servicing was made more difficult than the 250/350, thus not done so often

The first thing I did with this bike was to clean the filter and change the oil.  What I found was encouraging....the oil was clean and the filter too. At least the last owner was diligent in that respect.  As for his talents at restoration....well that's another matter!

Cheers

It seems the 360 was a bit of a marmite bike.  Maybe its problem was that it wasn't a 350  :)

Too bad... I like it.  It is bit different after all.

It has some serious big brothers to learn from in my garage

Bryan,

Maybe.  Perhaps no UK ones left, so fit a more available short one. Possible.

Thanks Folks,

That is reassuring that it is a UK bike as I understood it was.

My frame number CB360-10938xx does not match the UK portion of the Parts List which quotes CB360-1011300 with matching engine numbers.  Seems strange as Honda didn't do matching numbers, only matching ranges. Based on that, the engine might not be original CB360E-10395xx, however that number does not match the parts list for any country either.

I expect the parts list dated 1 March 1974 pre-dates my bike.  Somewhere there may be a later parts list.....

Thank you Ash for the downloads.

So the bikes that are for sale in the UK with the idiot light pod are mostly US or other country versions imported after period.

Ash,  My bike has a short rear mudguard, but it matches the parts drawing.  There does not seem to be a UK variation listed in country specific parts area of the parts list.....difficult to read those combined drawings and the detached parts list.  What nutter thought of that.  To do with microfiches I expect.

Bryan, Interesting about the insurance. That makes my bike really quite rare.  No wonder there is a dearth of parts.  However most of the bike's parts are universal, so the late other country imports are welcome here in my book.

What triggered this investigation is noticing that the mufflers were mounted in such a way that spoiled the graceful curve of the headers through to the end of the mufflers.  There was a kink suggesting that the mufflers were set too low on their brackets. CMS/DSS have confusing and contradictory images of these parts.  Ash's parts list shows brackets that look different to mine.   The brackets have different part numbers, but should be mirror images.  One of mine has a cut off section and a footpeg locating slot in the wrong place.  Bizzarly, I have seen photos of pillion footpads clearly using bracket like the dodgy one (leaning over 45º).  Maybe a CL360 bracket.  (See photo)

After this confusion I thought I would check the bike's details....so still confused

Sorry for the long ramble,

Cheers,
Jerry

SOHC Singles & Twins / CB360 Variants Question
« on: October 11, 2023, 08:48:17 PM »
Hi Guys,
I recently purchased a CB360, which I believe is a UK model as the V5 does not mention a previous registration abroad.  It is in nice order and goes surprisingly well.  However, I am puzzled by the variants that I see whilst researching this bike.

It was first  registered in July 1975, but it is possible that this bike is an old stock model from '74, or maybe even '73.

My bike has the front disc brake rather than the 2LS drum which the some? of the '73 bikes had.  My bike does not have the idiot light pod between the gauges, just the lamps in the speedo.  There do not appear to be any other obvious variants, Other than the CL360, so when I find '74 - 5 - 6 bikes advertised for sale most seem to have the idiot light pod.  The bikes like mine seem far and few between.

Looking on CMS, they only show the US versions.  DSS seem to only recognise the G5 model....whatever that means.

Is there a CB360 aficionado out there who can shine a light on it.  There seems to very little info about this short lived but attractive bike

Cheers,

One might have been a dud but both? Maybe our definitions of slow are different, when I was testing these it was back in the days of my production racing and that sort of skews your views on speed I'd imagine. Oddly I found the 250N a much better bike. The 400N even more so.

I guess jumping on one these after racing might just be an influence !  Ha ha!

My advise is just one word.

Don’t

Did you actually own one Ken? Or was it your experience in the workshop at Queenies of them?
 
Funnily enough, a few years back,  I had a blue G5 250  with only 2K genuine  miles that I pulled out from a damp shed basically got it for free... ..... Long gone now and the buyer did an awesome job restoring it  but when I brought it home and  cleaned it up my,  kids said it was one of the best looking bikes of all of the ones I have  ;D and wanted me to keep it ! It was a very late one, with the cam chain tensioner sorted out at the factory (another early Achilles Heel point  :( )  .....   pics attached are 'as I found' and after the  buyer restored it.

Plus the 360 version may be a lot less gutless than the more maligned 250. I think if the cam and head were OK on this it would be a decent project but there's the rub .. . Also pretty sure that Brituro amazingly do repro silencers (or they did) for that model. Another plus is that they are all painted in metallic, not candy paint,  so cheaper to repaint and Piki does excellent tank stripes. The guy at Summerbud (Nick? ) recently did some marathon run on a 360 version one for a charity event

On the CJ that replaced it they lengthened the forks and swinging arm, ditched the electric start and 6th gear and got rid of lots of the chromed bits. Now that model really is a Marmite bike with unobtanium 2 into 1 exhaust system as standard. Charlie at Oxford classics had  one last year that some bloke had fitted NOS parts inc exhaust seat etc but it had gained a 'patina' in storage, which put me off recommending it.

I did a couple of foreigners on them and the test rides were eventful. Slow, not as slow as the CJ version but so slow it just put me off. TBH it's not a bad looking bike but god it's slow. I like something that goes when you twist the throttle and this ain't it.

You must have had a dud!.   I have just bought one.  I was really surprised how torquey it is.  Very happy to tool around on this bike and I'm used to something rather bigger.

Really pleased with it.  Just spending a few bob on it to tidy it up.

CB750 / Re: Carb identification
« on: August 28, 2023, 10:16:43 AM »
Hi,

According to our US sister site, .net, the 7A carbs were fitted to the early K1 (like mine).  These bikes were made in the original 750 factory, before they moved to the "new factory" this I believe is when they changed to the 657.  However, it is my understanding that pretty much all the variants of these carbs are down to the internal configuration.  The castings look identical.  So I suggest you check the main jet emulsion tube to see if it matches your other 3 carbs (there are subtle differences, spacing and hole sizes and height on the tube), the jet needle height and of course the jet sizes.  It might be worth a check on the air bypass restrictor for the main jet emulsion tube too. (the little brass air jet pressed into the body in the intake bell)

Have fun.

CB750 / Re: Vacuum leak

One way to ell would be to spray carb cleaner at the top of the carbs whilst running to see if that influences anything and could point to a leak.
[/quote]

Yes but if have you wear on the rod in a position other than at tick-over, it might be difficult to detect if the seal is worn just enough to leak a bit at that point.
I'm thinking that maybe the most worn part of the rod is when going on off the throttle.  Clutching at straws here!

Cheers,
Jerry

Hi Pauarc,

Interesting.  I was wondering about air leaks here.  I don't see a part number for that other than a "Top Set", but the drawing is unclear.  Unlikely, but do have 4 spare parts for sale?

Cheers,

Jerry
