These kits contain everything you need to complete your rebuild the right way, the first time. High quality parts specifically chosen by us to match our forged pistons are included in this kit for easy one stop shopping. 2-stroke kits feature our Pro-Lite pistons that are CNC machined for optimal cam shape and profile for peak HP and service life. 4-stroke kits feature a ‘race-ready’ dome finish with smooth edges for improved combustion flow.
