CB 500 resurrection

[gary123]

Can anyone confirm the number of links in the cam chain please. Im thinking I have the wrong one.
It wont matter to much as I wasn't going to use it anyway, just having a trial fitting.

Like i said, i have seen the front chain cushion put in the wrong side of the chain making it impossible to fit the sprocket to cam, the cushion goes inside the chain facing forwards which is not the intuitive way of fitting.
If you look at an online parts book i seem to remember it saying how long the chain is but my books are stashed away at the moment

Bryan I am a complete nob. Exactly that^^^^. Had the picture in front of me as well. I really shouldn't be allowed a set of spanners. Thanks to all who replied.

You aint the first and wont be the last, by the way the slot in the end of the tensioner screw is for assembly purposes only DO NOT use a screwdriver to force the tensioner blade tighter, seen too many wrecked tensioners that way.
ALSO read, reread and read again the warnings in the manual on fitting cam cover, valves and guides are expensive now

Not sure if you've seen or heard of this Gary but everyone now (except me of course) uses elastic bands to hold the rocker arms up, just band the 2 together inlet to exhaust, so they pull each other up, you'll need 4 bands of sufficient strength. I've never done that myself as I tend to just lift them up by hand but TBH it's probably a better method than mine, almost fool proof. Wind the adjuster screws almost out as well. Better safe than sorry.

Trigger did it for me after reconditioning the head and rockers etc. [ Guests cannot view attachments ]

Late 550 rocker box instead of a 500 one, good mod to do as they are better than the 500s.

yes I thought that was the way to go.

OK I cant lie. Trigger just recond the best one I had. I had no idea there was any difference.

Those 4 bolts in the middle are to hold the rocker shafts to stop them rotating. The 500 doesn't have them and it has been known for the rocker shafts to oval out the camcover.  It was an upgrade by Honda to rectify that problem.

That makes sense.
Any clues as to the origin of this seat? [ Guests cannot view attachments ]

That could be a 550 F2. Are you selling it, if so first dabs please.

[Oddjob]

Looks like a 500K1 seat. Not a 550 as that has a tool kit holder on the rear.

I've not seen one with rubbers fitted in the air holes before though, probably fitted to stop the edges from rusting

Oh and to answer your question about the camchain, it's 88 links for the 500/550 although you've sorted the problem now.

It fits my 500 quite well, but if I can get a genuine 500 (or even a replica) at a reasonable price I will sell it and you def have first dibs.

[Oddjob]

That is a genuine 500 one Gary, the ones DS sells are replicas and don't fit as well as that will. Remove the cover and the foam and get the pan powder coated, just fit the 5 standard cushion rubbers. Check the bolt holes for the seat bracket aren't stripped out before having it powder coated. If they are get 2 nuts welded to the inside after removing the captive nuts Honda used.
