How Often Should the Drive Pulley Weights Be Replaced?

[VonDiana]

There is no specific replacement interval for drive pulley weights; it depends on the actual usage conditions. Generally, they only need to be replaced when worn. Additional information: 1. Basic introduction to drive pulley weights: One of the rotating components in scooters, the drive pulley weights (also called movable weights, capable of radial movement) are affected by the engine speed. As the speed gradually increases, the centrifugal force acting on the weights overcomes the force of the main spring, causing them to move radially outward along the sliding groove. This increases the force pressing against the axially moving driven pulley, enlarges the working radius, and reduces the diameter of the driven pulley, thereby changing the gear ratio. 2. Classification of drive pulley weights: They are divided into light and heavy weights.
