Recently went to Hatfield McCoy trails for a week...
On last day, last trail, last hill, my quad started making a whining noise that is relevent to engine RPM, and the unit is idling very rough and seems to have lost power, and smoothness. This started after a long, steep decent, down a trail. I thought perhaps it is the drive belt, or output shaft bearing, or clutch bearing, dealer tech thought it may be the harmonic balancer has moved.
What do you guys think??? Dealer says if it is the balancer, the drive belt, and pullys must be removed, as well as the transmission, to get at the balancer wheel that has moved and now is no longer in the balanced position, and that's a $1200 repair due to the hours of wrenching needed.
