Both problems can be eliminated with the installation of the APE manual tensioner. No matter what the engine does, the cam chain tension will remain constant. An APE manual cam chain tensioner is a must for any kind of performance riding.
Good but should include another nut to lock it place for good
Works fine. Took away rattle from OEM tensioner. Just wish it has another nut to lock the existing nut in place. If it ever backs off it will blow the motor. I installed my own lock nut
