It's almost a brand new motor. Only maybe a gallon through it at most. Don't know how to see if the cam surface is worn?
I did tighten the butterfly a lot. But Even with it this tight, I can still move the clutch arm over (of course I have to swing the carb out of the way) and the clutch releases. I assumed that I would want the butterfly as tight as possible as long as the clutch can still disengage, No?
Remember that yesterday after hard ride the clutch was stuck in the engaged position. Then after it cooled it was stuck in the DISengaged position. Then I removed the sprocket cover and tapped on the bucking bar an everything started working again. I can't understand how it went from being stuck Engaged to being stuck DISengaged just be cooling off?
