- Oversized cooling fins on cylinder for efficient heat dissipation
- 52mm piston with rings, pin, & clips
- Head gasket kit
- High performance race camshaft (11/4/04 - Updated camshaft - more aggressive lift and duration without sacrificing low end torque)
- Race Head – Larger valves and porting for increased performance. Also has bigger cooling fins. Includes all necessary parts and now comes assembled.
- 20mm Performance carb assembly. Includes: 20mm carb, intake, heatstop, gaskets, mounting hardware/wrench, air filter (not shown in pic) and long throttle cable (11/4/04 - Updated throttle cable - a new type is provided that allows for more adjustment and will work on wider selection of throttles. However, if you have the old type slide throttle, it will have to be replaced with a regular type aftermarket throttle)

We recommend purchasing a high volume oil pump kit (available in this section). 

Installation Note: It will save a lot of time and effort if the oil pump is installed while installing the bore kit (requires cylinder removal).

Upgrading my original motor

I was referred to this kit by various people on the forum and have had SO much fun putting it together... I can't wait to fire the bike up for the first time, and have been told that 70 km/h is not going to be an unreasonable speed to find myself hitting with this bigger bore kit! The support has been fantastic too - thanks again!
