The Stage6 Racing 70cc MkII cylinder kit has been improved in several respects compared to the previous version. It has continued with a strong nicasil coating in the cylinder passages, but the port times have been optimized so that the performance is up to 1 hp higher. In addition, it uses a Stage6 R/T Replica piston with a curved top and the same type of piston ring of 0.8mm as e.g. also used on the Stage6 R/T cylinder kit. In order to achieve the full effect of the putty, it is recommended to use e.g. larger carburettor and exhaust. A spark plug with a short thread must be used for this cylinder. The kit is delivered complete incl. gaskets, piston ring, etc. NOTE: ø12mm cross pin.
Note: The cylinder cannot be fitted to models from 2003->, unless the restriction in the engine block is removed. If the cylinder is fitted, it is no longer possible to use the original or other Euro2 exhausts. Both parts apply to models from 2003->. This does NOT apply to PGO engines.
