QMB139 super performance CVT transmission kit
If you are looking for a complete performance cvt kit for your Chinese scooter look no further. This CVT transmission kit has everything included in the kit. The only thing you will re-use is the nuts and washers that hold the clutch and variator on. The sweeet thing about purchasing a kit other than piceing out is it has been tuned. No mixing and matching springs and roller weights. Just install and go! The kit wil 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. 10 inch wheels are SHORT CASE, and larger is LONG CASE.
