108CC BIG BORE STROKER KIT
The kit now includes the proven Mikuni VM26 carburetor which will provide better performance and ease of tuning. Our Race Head has been updated for even more performance!This kit is the complete kit to convert your stock motor into a powerful 108cc engine (MUCH MORE POWERFUL than the common Chinese 107 and 125cc engines) with tons of torque!
The kit includes the following parts:
- 51mm Crankshaft with NTN bearings- NEW UPDATED Race Head – Larger valves ( 25mm intake & 22mm exhaust) and better flow for increased performance. Also has bigger cooling fins. Includes all necessary parts and comes assembled!- High performance race camshaft- Lightweight 52mm aluminum cylinder with steel sleeve, cast in mounts for skid plates, and larger cooling fins.- High compression piston with rings, pin, & clips- Crankcase and clutch cover gaskets- Head gasket kit- Genuine Mikuni VM26mm Performance Carb- Intake Kit for the Race head- Jet kit with 3 different sizes (Stock size is a #195 - Extra jets sizes of 155, 165 & 175)- Throttle Cable- Dual Layered Foam Air Filter
Most all CT70s will require a throttle change so the aftermarket carb will work properly. We sell two versions that will work but almost any generic normal Honda type throttle will work as well. (Most of the old throttles don’t have enough free cable to work on the bigger carbs.)
