i checked my valve clearances and found that my left intake valve was perfect (.06) and my right one was off a hair (.04). i have a 165 in the left side and a 170 in the right side. i changed the 170 to a 165 in the right intake and put the valve assembly back together. now BOTH sides are even tighter than they were before. i appear to be at top dead center judging from the kick start side marker and the cam chain sprocket and marker on the cam assembly and the rocker arm on the exhaust valves is loose. what did i do wrong? did i mess up the timing? this isnt my first shim job but my first solo. my bike is an 08 crf450r.
