DP 500A - Sportsman 500 HO

More aggressive acceleration for high performance riders. Includes a set of billet steel DaltonPro flyweights, a different primary spring, and a billet helix. Designed for use with the gearing and rotational mass related to stock tires, and in fact can benefit from using lighter weight wheels and tires (not larger than stock size). Not for use with oversized tires.
