Product Description

Bore: Yes
Stroke: No
Actual Displacement = 99.39cc

Engine Modifications Required:
Cylinder: Bore, Port and Replate with Apticote 2000 ceramic bore coating.
Power Valves: Kit comes with new valves
Head: Rechamber to work with the Big Bore piston. 100 octane suggested for most conditions.
Crankshaft: No crank mods required.
Crankcase: Crankcase mods required to clear piston.
Blueprint: Calculate deck height, squish clearance, trapped volume, port timing and compression ratio and list on your perminant Spec-Sheet. (Some operations with install only)

Notes: This kit runs circles around stock RM100's. Of course it is not a stroker engine but for racers on a tight budget looking to compete in the Supermini classes, the RM100 kit is the best option for you. It has many of the same charistics as the RM105/112 packages but is just down on torque. You will not go wrong with this choice.

Notes: This kit is commonly called a 105cc kit by other companys.

Notes: This kit requires you to send us your cylinder, head, and powervalves for modification.

Notes: Core parts subject to inspection before credits will be issued.

Notes: Must use a RM85 cylinder. We will not accept RM80 or RM100 cylinders for cores.
