Description
Camshaft Naraku Racing Yamaha Cygnus / BW's 5ML, for Yamaha Cygnus / BWs 125cc (5ML - 4 valves). It is a tuning camshaft with longer valve timings. Valve timing determines when the intake and exhaust valves open, how long they remain open, and when they close. This in turn affects throttle response as well as torque and hp at any given rpm. The camshaft can be used with original as well as tuning cylinder heads. Please keep in mind that the variator may have to be readjusted.

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.
