Complete drive kit consisting of Naraku components. Ready to install! All components are carefully matched to each other. Since in Chinese scooters sometimes not the highest quality components are installed from the factory, this is the easiest method without expert knowledge about the function and tuning of the individual components to overhaul or repair the complete drive unit. All throttles in the drive unit are thus eliminated. It increases not only the top speed, but also the starting performance on the hill.
The kit includes variator, vario sleeve, variator pulleys, V-belt, V-belt pulley, clutch & clutch bell and the converter pulley. Suitable for all 4-stroke scooters with 139QMB engine and a V-belt length of 729mm.
The kit is designed for scooters that are in original condition, if changes have already been made to the exhaust or cylinder, the variator must be retuned and if necessary a harder back pressure spring must be fitted.AI-translation
