2001-05 (Bottom-mid-range for use with stock or oversized tires)

Our most popular kit for the 500HO, it is designed to increase belt grip and acceleration, without losing top speed with stock tires. This kit also works well to restore lost power resulting from bigger tires. Engagement is only slightly higher than stock. Includes billet steel DaltonPro flyweights, new primary spring, new secondary spring. Designed for use with the stock helix, and with stock or oversized tires.
