This Camshaft is good for 450cc XC/Trail engines. This cam will increase mid range and help top end. It will produce a very wide torque curve. Porting is Highly Recommended with this camshaft. Aftermarket Valve Springs are required for this cam (KW, Web, or PSI Springs recommended). Larger Followers are highly recommended. Will require shortened or sunk valve guides and may require cam-tower clearance.
