I just bought a 2004 WR450 F with a Rekluse clutch Pro with heavier balls installed and the Clutch perch. I was told to ride it starting in 2nd gear. I can feel the clutch pulling in 2nd gear, but it is slipping. In first gear it pulls harder. I rode it again when I got home and when I got down the trail, I tried to stop, but the clutch did not disengage. It stalled. Any recommendations for adjusting the setup?
