This kit is under development at time of catalog printing. The staff at Speedwerx has been working some serious overtime on this kit. This kit is designed so that you can have the same great handling performance the new Sno-Pro chassis offers any where you want to ride even if premium fuel is not available. Kit is planned to include new head inserts, larger capacity cooling system upgrade, new jetting specs and Speedwerx clutch kit. Contact Speedwerx for more information.
