SKI-DOO 500SS and TNT Engine
RK Tek has developed an Over-Bore kit for the 500SS/600 Series III Engine.
This over-bore turns your 600cc engine into a 662cc engine. We use the same piston in this kit that is used in out 738cc over-bore (600HO and 700 Series III Engine). Besides the awesome power increase, the benefit of not having the power-fade associated with the single ring piston (OEM) is what you will really notice when running this kit.
This kit consists of the following:
Bore cylinders to 80mm: $195.00/pair
Port cylinders to RKT Specs: $600.00/pair
Custom RKT Billet head: $465.00
Custom base gasket and spacer: $60.00
RAVE valve modification: $80.00/pair
Custom machined 80mm CAST pistons: $350.00/pair
Wrist pin bearings: $40/pair
