I use to go through alot of clutch bearings too. Can you reverse your clutch shoes on your set up? That stopped killing my bearings. Its the heat that caused mine to burn out fast, built up by the lack of good grip from the shoes trying to grip. Toki knows how well the shoes grip when reversed. I dont know if thats your problem, might be something else, but it really helped my bearing life out alot. Sometimes if your over geared it can put alot of load on your clutch too and cause alot of extra heat that kills off bearings fast. If your tune is off or your running in high grass that will do it too. Duno, I am presuming your mesh is right?
