QMB139, Buddy50, Roughhouse Super Performance CVT Transmission Kit
This will give you quicker acceleration, higher top speeds, and makes your CVT the smoothest operating trans around! It comes with a weight of 9G rollers, but we would suggest a roller tuning kit to get you completely dialed in. From there you can find your weight and upgrade to some Dr. pulley sliders. From rapid down shifting to slow cruising, this thing is smooth. Ultralight balanced components, oversized wear pads, and state of the art PTFE coatings ensure superior performance and long service life.
