1 x Racing Camshaft for 139QMA/QMB engines
Component No: NK500-02
Colour : Standard

The latest version of the Naraku Sport Camshaft V2 offers improved reliability and engine smoothness over the previous version. This is addition to V1 benefits of increased acceleration and slight improvement on top speed. The V2 camshaft is developed for everyday riding while not compromising on performance.

Compared to a complete engine block and piston change a camshaft replacement is far easier to fit and offers what most rider are looking for, increased acceleration and mid range pull. This camshaft offers increased acceleration (32% according to actual tests, see diagram below). The camshaft is suitable for use on all 139QMA/QMB engines between 49cc and 90cc.

The camshaft has modified cams to improve fuel intake and exhaust gas expulsion. No modification is necessary to any of the original cam house, head or valves, its simply plug and play. We do recommend that the variator roller weights are tuned to camshaft as the torque curve of the engine is modified.
