Description
Camshaft Naraku Racing, Kymco KXR, MXU, Maxxer 300, Dink 250, for Kymco / PGO 250-300cc models. It is a "high-lift" tuning camshaft with longer valve durations. High-lift camshafts lead to increased duration in the high-lift regions where cylinder heads flow the most air, responsiveness, torque and power are considerably improved. Using this camshaft gets rid of the automatic decompression system, but no worries, you won't notice a difference when starting the engine.
The camshaft is designed for 250cc engines, but can equally be used with 300cc to unlock its full potential.

Camshaft and valve timing
The camshaft and valve timing are important components of 4-stroke engines. The camshafts allow the valves to open (i.e., to draw in the mixture and expel the gases) and are driven by the timing chain, which is in turn connected to the crankshaft.
Incorrect timing adjustment interferes with valve opening and can severely affect engine performance and reliability. Therefore, we recommend to intervene only with appropriate technical know-how.
Maintenance and tuning
Maintenance and care of the elements located in the cylinder head, including valve timing, is very important. Even though the timing chain generally has a fairly long life, it is still necessary to regularly check chain wear and wear of all related elements.
Camshafts must always be in perfect condition. You can also use tuning camshafts; the shape of the cams is revised to increase the valve opening times and thus provide more power.
Tuning Level: Racing
We categorize our products into different performance levels Original, Sport, Racing and High End , so that our customers can choose the right parts for their setup. It is really important to combine parts that belong to the same tuning level, this is especially true for cylinders, crankshafts and exhausts.
Racing products are designed for a more extreme uses and are developed primarily for racing. Whether you stay at 50cc or increase the displacement, the corresponding Racing parts produce much higher performance than the original parts in order to achieve maximum power.
