I'm new at owning a scooter and this is my first post. I'm trying to upgrade my clutch on a GY6 150 scooter. Could anyone tell me why I would need a performance "torque sheave"?  And where exactly is this located? Behind the clutch assembly? How does it work?

It's behind the clutch,,,and works in conjunction with the contra spring,,,,to bring power on earlier so the torque is there when you need it,,,down side? Belt wear
