The Dr Pulley variator kit for GY6 150 engines is a high performance variator for scooters with wheels up to 13 inch plus go carts and ATVs.

Scooters with wheels above 13 inch (except Kymco with 14) will need to use GY6 B variator kits that use slider weights at 20X15.

With increased angle on ramp plate plus taller drive plates your scooter will have a noticeable increase in bottom end torque as well as top end speed. The sliders alone increase plate pull and push out due to design as well last longer due to slide on falt side so no more flat spots on roller weights.
