hi, i just checked the valves on my 04 crf250r, and the exh. valves were right on....however, the left intake valve feels looser than the right.... left measures between .005" and .004" (i dont have anything in between). well, .005 is too loose, and .004 is kinda tight still. the right intake is a little tighter than the .005 should feel. is this normal? i would estimate that i have about 75 hours on the engine now, i do not race at all, just play around on some logging roads here in alaska. i thought that the valves would only get tighter as time went on. thanks for any help and advice you have !!!
