I'm with rich on this. We went through this on both of our foremans when we put STP in the oil, and my clutch is slipping right now due to using Lucas break in additive. It's honestly best to just run oil if you want the best performance you can have, my $.02

We had used STP as well and it made our clutches slip. My point was that we have found that additives usually do good, but make our clutches slip usually. Honestly, we ride balls to the wall, and we notice it in higher gears. Unless you ride hard you may not ever notice that it slips a little

Good luck with it then, you've had better luck than me :lol:
