A very large kit very famous for having a very high power while being extremely resistant.
The CORSA polini or race in French is a d.47mm kit in cast iron retouched by hand with very advanced diagrams. It retains a normal exhaust as well as a twin segment piston which allows it a lot of torque and robustness.
It will reach powers of a majority of stock aluminum kit (not retouched). It comes with a carburetor adjustment nozzle, a cold racing candle, carbon racing valves studied in the kit.
Its piston is reinforced and worked with the kit, its cylinder head is polished frustoconical really well calculated which allows it a very good power by adding a good squish. The cylinder which remains in 5 transfers but has a revised and corrected admission and everything is in the diagrams retouched by hand!
We will also appreciate the reinforced O-ring seal which avoids many worries well known on this type of engine: the flat aluminum seals that break. Noted the finish of the lateral transfers which leaves something to be desired.
We recommend it with at least: reinforced crankshaft, 21mm carburetor and adjustments, reinforced bearings, racing exhaust.
