Primary chain and rubbers

[Sesman]

Help needed please. I’ve seen lots written on this topic, but would appreciate some advice on an economic  source for primary chain, primary rubbers and cam chain.

Would also appreciate some advice on the can chain tensioner blade. I can’t make out if the blade should have chain run witness marks or if as new it should be flat.

Primary chain kawasaki, cam chain did, rubbers Honda.
That tensioner is fine unless the rubber is spliting off the ends

[Sesman]

Thanks Bryanj. No evidence of splitting at the ends.

Cheers.

I followed Bryan's advice and used a Kawasaki primary chain on my CB500 K1. Here's a link to the supplier I used.

Hi, Oddjob. Really appreciate the insights and to be fair I’d already resolved to replace the blade. I’m not on too tight a budget and I won’t be ‘going in’ again.

I’d budgeted for primary, primary rubbers, cam chain and potentially new shells. I’ll also be replacing the main shaft bearings. The bores and pistons are ‘pristine’, but I’m refreshing with new rings and a head overhaul. The guides and valves are fine, though the exhausts are surprisingly heavily carbonised.

High Charlie J. Thanks for the info. That will save me a few Bob. Presumably the cB550 and CB500 primaries are identical?

[Sesman]

Sound, thanks.

The grooves  are cut in by the chain sodeplates within a very short time the the rollers run on the rubber, i was trying to gauge how far the centre was below the outers and it looked negligible in the photo

[Sesman]

I’d say this is shagged?

[Bryanj]

Furkled, crodged, burglered or any othe adjective you have

[Sesman]

CB650 tensioner….is this a ‘bolt on’ or a fiddle?

[Bryanj]

Machining work plus the problem of finding one

[Sesman]

Ok, thanks. New chain and leave as standard.

Blade, blade rubbers, primary rubbers, primary and camchain now ordered.

I’ve discovered that the rear 16mm engine mounting bolt doubles nicely as an improvised slide hammer to remove the primary shaft. But I’m guessing most on this forum already new that?

[Sesman]

Anybody know where I might obtain the primary output shaft bearing part no 91002283000.
Part no34. Seems to be unobtainable?

Hi, oddjob. Thanks for that. The engine is in bits, lots of them. Amazing how much space a dismantled engine occupies. I’m reading those articles right now.
