My 08 yz450 has excessive play in the clutch lever. The clutch lever bolt is tightened to spec( actually a little more snug). I have kicked around the idea of inserting a very thin shim/washer to take up the play between the lever and perch, but the shim/washer would have to be extremely thin. I have no other reason to replace the stock lever and perch. Does anyone have a fix aside from buying an aftermarket lever and perch?
