CB 500 resurrection

some progress photos.
Are these the correct footrests cos as you can see the mounting bolt is to short and I'm pretty sure its the right one. (I actually have three if anybody needs one) [ Guests cannot view attachments ] [ Guests cannot view attachments ] [ Guests cannot view attachments ] [ Guests cannot view attachments ] [ Guests cannot view attachments ]

Looking good. I'll take a photo of my foot pegs if it helps. Did you fit new Viton O rings in the carbs?
The engine bolt should definitely stick out further than that through the foot peg, as you need to get a nut and washer on yet.

i reckon the bolt may be off a 550 f1/f2 as the footrest on those mounts slightly differently. The correct one is threaded at both ends with separate nuts and is a bit longer.

Here you go.

I'd buy new float bowl screws, they appear too short and they are meant to be JIS screws with a split washer underneath so they don't vibrate loose.

The carbs also need bench setting, they appear massively out of balance looking at the adjuster screws.

Are the carbs 550 or 500 ? There is a number on the side to ID them. CB500 carbs run different needles and jets to the 550

Thanks for the pics with such a mix of parts its hard to know what is genuine 500, Ive got some 12mm all thread so Ill cut to size and use that.

If you need any more reference photos, just shout and I'll email them over to you.

There are no numbers on the carbs-just kei hin.

The carbs are always numbered. Here's the numbers on one of our 500/4's that's close to hand. 627B Keihin. Yours should have this number or if they are 550/4 carbs, they will be 069A.

Wow no wonder I missed it. Wife always says im half blind. I have those numbers so at least I have the right carbs--thanks.

Hi Gary, interesting to read your progress so far - tbh I suspect that had I been a sucessful bidder I would have found your build too challenging as I am not experienced enough to assemble a bike I did not dismantle in the first place.

The green shoots of envy are clearly vissible on me as I read your progress to date. Cheers Ted

Hi Ted
I thought the same, my previous restorations were always on a complete bike with a running engine.
But I thought the price was ok and I now have that most precious of resources, time. And of course this forum which has already proved invaluable.

[gary123]

So now for the engine. This is into the unknown so any feedback appreciated.
A local mechanic says the pistons will be good to use with new rings??
I have two camshafts should I be aware of any markings as to the correct one. They appear identical and measure up in spec so maybe either will do.
