A very large kit renowned for having a very high power while being extremely durable. The CORSA polini or race in French is a d.47mm cast iron kit (PATA NEGRA) hand retouched with very advanced diagrams.

It retains a normal exhaust and a bi segment piston which allows a lot of torque and strength. It will reach powers of a majority of stock aluminum kit (not retouched).

It comes with a carburation adjustment nozzle, a cold racing candle, carbon racing valves studied kit. Its piston is reinforced and worked kit, its cylinder head is frustoconical polished really well calculated which allows it a very good power by adding a good squish.

The cylinder that remains in 5 transfers but has a reviewed and corrected admission and everything is in the charts retouched by hand.   Will also appreciate the reinforced ring gasket that avoids many well known concerns about this type of engine: aluminum joints flat broke.

This kit also comes with a reinforced needle cage and greased. Noted the finish of the side transfers that leaves something to be desired.
