## Description (the store's own text)

- Lightweight aluminum cylinder with steel sleeve (huge weight savings over your stock cast iron cylinder)
- Cast in mounts on cylinder for aftermarket skid plates
- Oversized cooling fins on cylinder for efficient heat dissipation
- High compression 54mm piston with rings, pin, & clips (replaces your low compression dished or flat top piston)
- Head gasket kit
- High performance race camshaft (for the Race Head only)
- **\*\*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!**
- 26mm Mikuni carb assembly. Includes: 26mm carb, intake, heatstop, gaskets, mounting hardware/wrench, Improved Dual Layer Air Filter and long adjustable throttle cable

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).

This will make a huge difference in performance over your stock setup and is a very quick and easy upgrade. This kit will work on all 86cc through 107 Chinese engines

Except models with a 3 valve head.the cylinder stud spacing is different on SDG 107 (SDG SPEED MINI 107)

Our Race Heads will work with your 2 valve head and will come with our huge Race Cam.
Additionally, our Race Head uses Honda type cams so there are many cam options available for your particular type of riding, unlike the limited selection of cams available for the Chinese heads.

Electric start motors may require some mods to cooling fins for clearance

Chinese engines must use honda crf50 cam sprocket TBW0861, not included avalible in this section
