The Polini Corsa 70ccm is made of cast iron with the same diameter as the Polini Sport 70ccm, but thanks to larger gates the effect is raised. It also works at slightly higher speeds, but can still be used for everyday driving. However, we recommend that this be done in combination with mine. DellOrto 17.5mm carburettor and possibly. an exhaust such as Polini For Race or Top Performances Nardo Replica. For cast iron cylinders, we always recommend a run in min. 200km. For this cylinder kit we recommend using an NGK BR8ES spark plug and the kit is supplied complete incl. gaskets, piston rings, etc. NOTE: With ø10mm creep.
