  1. Hey All, I have a 2004 CRF 450R and I'm trying to check My valve clearances to determine weather or not I need to re shim. In checking the clearances I found that the left intake valve was way out of spec (to tight) more so than the others. The factory spec is .006 IN. (.152mm) I can't even get a .015 IN. (.038mm) in there but it's hard to tell because the feeler gauge is so thin it bends. Does this sound like head or valve damage or should I try to re shim back to spec??? Thanks For Your Input, Motox 44
