Aluminum cylinder with steel sleeve - High compression large dome 57mm piston with rings, 14 mm pin, & clips - Head gasket kit. This will make a very nice difference in performance over your stock setup. Additionally, it 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. The kit includes a steel sleeved aluminum cylinder, light weight high revving piston and a head gasket kit. Important Note: This kit will only work on Chinese 120cc and up engines with a 14mm piston wrist pin.This kit is also recommended for use only with big valve heads such as the common Lifan head with 27/23mm valves or our Import Race Head with 30/23.5mm valves. Installation Notes : Its very important that you use Hondabond (or similar quality) sealer on the head gasket.
Also, 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.
