The bike is a 2005 WR450FMeasured my valve clearances yesterday, the feeler gauges i have are. 0.1 ; 0.15 ; 0.20 , 0.25; 0.30 etc. Inlet valves .10 feeler went in, .15 did not. (Spec is between .10 - .15)Exhaust valves .15 went in nicely .20 did not. (Spec is between .20-.25)So this means I have to shim my exhaust valves. But before i can do this I probably need to get a more accurate set of feeler gauges in order to find out what size shims I need?
