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