Hello, excuse my ignorance in this matter but I've always had a shop do this, now the shop's closed and it seems no one's interested or got the tools anymore. I've just rebuilt the engine
on my 1975 Z1B and after grinding all the valves in and fitting a couple of new valve guides most of the shim clearances are tight and I cant fit a feeler gauge into the gap. How do I determine what thickness shim to fit, how do I get them out (surly I don't remove the cams to do this), I believe as a fully paid up member there is a ship swapping service I may be able to use, any help would be appreciated.
Regards
Stinky.

Re: Shim adjustment
Hi stinky
in order to remove the shims you need a special tool from Kawasaki (n° 57001-113), a valve shim tool.
I think that" Z-Power" or "Biker's toolbox" can supply you one.
When using the tool don't forget to take the valve cover gasket off.
To determine what shims you need is not so easy when the cylinder head is mounted.
I would suggest that when you take a shim out, measure its thickness, and depending on the clearance you had when it was mounted, take one that is at least 0,1 mm thinner. Keep in mind that when the valves are grinded and removed, they have a tendency to "set" after the engine has been running.
I would also suggest to get a workshop manual. It's all clearly explained in there, if you don't have one or can find one, just give me a shout and I'll try to explain to you how to do it in a safe way.
Good luck
