This highly durable clutch designed and built for direct drive mini-bikes and go-karts, one of the most rugged applications ever required of a modestly-priced automatic centrifugal clutch. Having extra ability for rough service. For up to 13 horsepower 4 cycle engines. Approximate engagement of 2300 rpm
Use Engine Crankshaft Diameter and Chain Size to determine the appropriate clutch needed
Most 2 to 7hp 4-cycle engines have a 3/4" shaft and typically use #35 chain. Some use the heavier #40/41 chain.
The 10 tooth clutch will give you a faster take-off and lower gearing for climbing hills.
The 12 tooth clutch will give you more top end speed
