Available in Stages 1 to Stage 4 ..... MORE DETAILS POSTED BELOW. Clutch Break-in Procedures: During the first 100 miles, never idle away from a stop, always bring the rpm’s up to at least 1,500rpm before letting the clutch out. If you don’t do this, the clutch will begin to chatter. Clutch will have less play from disengaged to fully engaged than a stock clutch does. No hard launches yet. Do not apply full power yet. The next 100-300 miles the Clutch should engage very smoothly. If it ever gets chattery, hold the rpm's higher than 1,500 and slowly let the clutch out in 1st gear, keeping the rpm’s at a higher rev. Doing this once will eliminate any chatter. You can apply full power now. No hard launches yet At 300 plus miles Clutch should be completely broken in. Hard launches are fine. Full power is fine. ------------------------------------------------------------ THIS ITEM CAN NOT BE RETURNED UNLESS THERE IS VERIFICATION BY THE SPEC TECH (HELP) LINE.
