The Stage6 Racing 70ccm MkII cylinder kit has been improved in several respects compared to the previous version. It continues with a strong nicasil coating in cylinder passages, but the door times have been optimized so the performance is up to 1hp higher. In addition, it uses a Stage6 R / T Replica piston with a curved top and the same type of piston ring of 0.8 mm as i.a. also used on the Stage6 R / T cylinder kit. To achieve full effect of the kit, it is recommended to use i.a. larger carburetor as well as exhaust. A long-threaded spark plug must be used for this cylinder. The kit is delivered complete incl. gaskets, piston ring, etc.
