Malossi 50cc sports cylinder for all CPI/ Keeway and Generic models (from 2003 on). Malossi sport 50 cast iron cylinder with altered timing and larger outlet port for an extra 2-3bhp. Designed for CPI/Keeway, Generic models, so no issues with oil pumps fouling the cooling fins. Cylinder includes all small parts such as gaskets, piston and head. Works very well with Yasuni Z or Laser XPro exhaust systems.
