I have two clutch issues. Once you accelerate over 2500+ rpm the pedal loses it free play and gets harder to push down when shifting then at about 4000-5000 rpm when the motor starts making some horsepower the clutch starts slipping. The strange thing is that the old clutch also slipped like that. This is the clutch that I have. Hays 85-301 Hays Street/Strip Clutch Kits | Summit Racing​
