Abstract
A flyweight comprises a body. The body of the flyweight comprises a pivot, a cam surface, and a first coupler. The first coupler is configured to selectively couple at least one first weight to the body distal from the cam surface. A flyweight comprises a body having at least 20% of its mass positioned to contribute negative torque about a pivot related to an acceleration of a CVT clutch from an idling condition. A method of tuning a flyweight comprises attaching at least one first weight to a first coupler of a body of the flyweight distal from a cam surface of the body. A CVT clutch comprises at least one flyweight with a first coupler configured to selectively couple at least one first weight to a body of the flyweight distal from a cam surface.

A flyweight comprising:
- a body, the body comprising:
- a pivot;
- a cam surface;
- and
- a first coupler configured to selectively couple at least one first weight to the body distal from the cam surface.
A method of tuning a flyweight, the method comprising attaching at least one first weight to a first coupler of a body of the flyweight distal from a cam surface of the body.
A CVT clutch comprising:
- a flyweight comprising:
- a body, the body comprising:
- a pivot;
- a cam surface;
- and
- a first coupler configured to selectively couple at least one first weight to the body distal from the cam surface.
A flyweight comprising:
- a body, the body comprising:
- a pivot;
- and
- a cam surface;
- and
- wherein at least 20% of the mass of the body is positioned to contribute negative torque about the pivot related to an acceleration of a CVT clutch from an idling condition.
