Naraku Sport V.2 70ccm is a powerful and durable cylinder kit that can easily withstand daily use - very much in the style of DR Racing Evolution 70ccm and Polini Sport 70ccm. The effect is significantly higher than with the original cylinder, but no more than the original crank can still be used. The cylinder is made of cast iron and we therefore recommend a drive of around 200km. A spark plug with a short thread must be used for this cylinder. The kit is delivered complete incl. gaskets, piston rings, etc.
NOTE: Top piece is not included and is supplied with a ø10mm cross pin.
NOTE: The cylinder kit has a ø10mm cross pin. In order to guarantee that this cylinder fits your machine, we recommend that you measure your current cross stitch.
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.
