Description
 

- NEW Ceramic coated all aluminum cylinder (no steel sleeve)
- High compression 57mm piston with rings, pin, & clips (replaces your low compression dished or flat top piston)
- Head gasket kit

This will make a huge difference in performance over your stock setup and is a very quick and easy upgrade as it does not require case boring. We found the right level of compression for increased performance while also keeping reliability in mind. We also just added an all aluminum ceramic coated cylinder.  This new cylinder is lighter than a steel sleeved aluminum cylinder, reduces friction (increasing power), improves sealing, and provides better heat transfer (runs and cools down quicker). For additional performance, add the 26mm carb kit available in this section. NOTE: This kit will only work on Chinese 120cc engines with a 52.4x55mm bore and stroke and a 14mm piston pin. Common models are SDG/Sikk and RCM but there are so many Chinese brands/models that you absolutely need to know your bore and stroke and piston pin size. Many vendors also call 120cc engines "125" so its important you get the actual specifications from your engine vendor. Unfortunately, we are unable to tell you what you have based on a brand name.  INSTALLATION NOTE: Don't use the original o-rings between the head and cylinder (not needed) but do use the large o-ring at the bottom of the cylinder between the cylinder and the engine case at the oil return.
