I'm rebuilding a basket case engine, 81 cb750k. The valves were not labeled or numbered. So I just cleaned everything and gave them a lapping.
I'm at the point where I'm setting the valve clearences, yes I know, .005.
So, I couldn't get a .0015 in with a the smallest shim I have, 2.75. So I ordered even thinner shims and again, even with a 2.30 shim I can get my smallest .0015 feeler guage in. What the heck? Yeah I lapped them but not that much.
Any thoughts?
