Description

This kit is the complete kit to convert your stock motor
into a powerful open class 108cc engine (much more powerful than
the common Chinese 107 and 125cc engines). Also, this crank was made specifically for the newer
engines and thus, you will not have any fitment issues like trimming the piston
skirts in order to clear the crank or the piston not lining up with the cylinder
deck. The kit includes the following parts:

  • 51mm Crankshaft with NTN bearings
  • High compression piston with rings, pin, & clips
  • NEW Race Head
  • Larger valves (now 25/22mm) and better flow for increased performance.

Also has bigger cooling fins. Includes all necessary parts and comes assembled!

  • Lightweight aluminum cylinder with steel sleeve, cast in mounts for skid plates, and larger cooling fins.
  • High performance race camshaft
  • NEW Genuine Mikuni VM26mm Performance Carb
  • Intake Kit
  • Jet kit with 3 different sizes (Stock size is a #195 – Extra jets sizes of 155, 165 & 175)
  • Throttle Cable
  • NEW Dual Layered Foam Air Filter
  • Crankcase and clutch cover gaskets
  • Head gasket kit
