+ 1 on the TKO special steel clutch bearing. I've got nearly 2 gallons on mine and I have not touched them. The bell spins as freely if not better than when I first installed them. No grit or anything. I blew out the standard kit Agama bearing on the front of the clutch bell within 1 tank and thought f this. This can't be happening. Switched over to these TKO's and man they just work. No maintenance, nothing.
