Mine is running standard gearing that is being replace with a 520 kit again gearing left the same. When I set off fast on mine slipping (you may call it riding the clutch)the clutch the rear tyre is trying to let go and the front end is coming up.
“Clutch control refers to the act of controlling the speed of a vehicle with a manual transmission by partially engaging the clutch plate, using the clutch pedal instead of (or in conjunction with) the accelerator pedal. The purpose of a clutch is in part to allow such control; in particular, a clutch provides transfer of torque between shafts spinning at different speeds. In the extreme, clutch control is used in performance driving, such as starting from a dead stop with the engine producing maximum torque at high RPM”.
