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
