hey guys, out last weekend and after a good ride, the bike started making a scrubbing sound from the lower end. was not able to tell which side it was coming from but it was consistent with engine speed. I have drained the oil from it and there are no signs of destruction yet, getting ready to take off the outer case and see whats going on inside. Any thoughts or ideas? Also, anyone know of a good carb tuning guy near Athens GA?
