Clutches should be set to the engine’s maximum torque rpm. If you don’t know the peak torque rpm, set the clutch to a low rpm. Acceleration will be lazy but you’ll do no damage. Adjust upward in small increments. If you don’t know the peak torque rpm and set the clutch too high you will have lazy acceleration and a fried clutch. The two biggest reasons why clutches overheat are wrong engagement rpm and bad sprockets.
