drive face boss / vario bushing Naraku racing - unrestricted - 20x38mm

This Variator sleeve replaces the original factory fitted sleeve and collar. This lifts the restricted power. The scooter will be capable of approx. 46 mph (for a 2-stroke).

This sleeve is a requirement for any later tuning work. This is step 1 and an absolute must if you intend to fit a cylinder, exhaust, carb etc. Otherwise the engine goes pop.
