Hi there,
I checked today the valve clearness on my CB750F 1980, all 15 valves where in the correct tolerance except the the 2 exhaust valves on cylinder 4 that are well to close, I couldn't even insert 0.002 inch feeler gouge, very tight, almost no clearness at all.
I got this bike from a guy that told me it was standing for years, so I basically replaced all rubbers, oils, electrics, put CR carbs and did not fire the engine yet.
I have a shim removal tool, should I change to a thinner shim?
Isn't it strange that all valves clearness are fine except 1?
Shouldn't clearness increase in use not become smaller?
Please help,
Thanks,
Eli.
