Anyone check for clutch binding on the sleds that won't top end? I was playing around with my clutching last week and could not get full shift, regardless of set-up it was about 1/4" from shifting out. Going to dig a little deeper, the bottom and mid pulls so hard I don't believe the motor is down on power. (F1000 w y-pipe and bullseyes.) Something has got to be holding these things back. Some run real strong and others just hit a wall around 100. Even if a guy had one that was mapped too rich on top and instead of getting 13-15 hp from the y-pipe and bullseyes only got 3-5hp it should still do better than 100. I've read the other posts about the octane and DD fluid levels and maybe they're part of the solution but I'm thinking there's more to it. With the season running down I would sure like to get it figured out before the next one starts.
