The Koso 240 Degree Performance Camshaft (MM623002) will give you great results at high RPM. This camshaft can be used with a stock engine, but will even give better results with the Koso 170cc big bore kit. Made from quality material for longer durability, the Koso GROM camshaft is a clever choice!Performance cams typically have a duration ranging from 220 up to 280 degrees or higher. The higher the duration, the rougher the idle and the higher the cam’s power range on the RPM scale. A cam with a duration of 240 degrees or higher will typically produce the most power from 3,500 to 7,000 RPM.
Aftermarket fuel controller and upgraded fuel injector is required. Professional installation is highly recommended!
