How will a clutch kit affect speed?
Very little. The major thing to remember when clutching ATV’s is that changing clutch components changes the rate of shift on the CVT system during the “clutching phase”. The clutching phase is when the belt travels from low ratio to high ratio (high ratio is when the belt is to the top of its travel on the front motor clutch). The goal is to control the shift RPM properly during this clutching phase. On most ATV’s this “clutching phase” is over in a distance of approximately 500 – 800ft. This is very different from snowmobiles, where much taller gearing makes the clutching shiftout phase last up to ¼ mile. On some ATV models, tuners often mistake “shift out RPM” for “after shift out RPM”. Clutching changes the rate of shift…. But when the belt reaches the top of the primary (motor clutch)…. It is to the top. Clutching cannot add more gear ratio. Proper kit selection is important on some models, as different calibrations can make the clutches stay “shifted out” in high ratio at differe
