Ski Doo 500SS Big Bore Kits
The Series III 700 Twin is BY FAR the most impressive 700 twin on the market!! However;as you read above (hopefully), it is plagued by poor heat conduction from the piston to the cylinder wall via the ring. RK Tek tried various combinations, including cryo-genics and other treatments.. but was unsuccessful in solving the problems associated with the OEM pistons and rings.
