I just bought a Yukon 150 at an auction for my daughter. I was wondering if there was an adjustment for the clutch. It seems that she has to rev the engine too high for the clutch to engage. As a result, she is going too fast. The unit is brand new, but since I didn't get it from a dealer, I have no one to ask. The closest dealer is 70 miles away. Will the clutch get better once it is "broken-in"?
