If the slipper is locked up it can contribute to a gear failure....
A properly adjusted slipper really helps absorb the shock from hard landings...
Hope this helps....
Yep , your slipper is too tight , I went through this too till I adjusted the slipper . That or buy a Robinson Racing slipper/spur cause it seems to work alot better at taking the shock loads from on power landings .
That or change your driving style , no on power landings , try to be easier on the throttle ect .
