QMB139 Super Performance CVT Transmission Kit
If you are looking for a complete performance CVT kit for your 50cc Chinese scooter look no further. The sweeet thing about purchasing a kit other than piecing out is it has been tuned. No mixing and matching springs and roller weights. Just install and go! The kit will give you a much better acceleration and top speed. Install time is around 30 min. Before you purchase this kit be sure you know if your scooter has a short or long case engine. The kit remains the same, but the belt length changes. You can figure this out by simply checking your tire for the wheel size.
