NOTE: When installing this kit, a needle bearing with a width of at least 14.5mm must be used. We recommend Needle bearing - Stage6 HighQuality ø10mm (10x14x14.5) .
The Stage6 Racing 70cc MkII cylinder kit has been improved in several respects compared to the previous version. It continues with a strong nikasil coating in the cylinder passages, but the port times have been optimized so that the output 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. For this cylinder, a spark plug with a short thread must be used, we recommend NGK BR9HS . The kit is delivered complete incl. gaskets, piston ring etc. NOTE: ø10mm cross pin.
NOTE: When installing this kit, a needle bearing with a width of at least 14.5mm must be used. We recommend Needle bearing - Stage6 HighQuality ø10mm (10x14x14.5) .
NOTE: The cylinder cannot be mounted on 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.
