*Now delivered without candle
A very large kit very renowned for having a very strong power while being extremely resistant. The Polini CORSA or race in French is a kit d.47mm made of cast iron (PATA NEGRA) retouched hand with very deep diagrams. It maintains a normal exhaust and a dual-segment plunger which allows it a lot of torque and robustness. It will reach the power of a majority of stock aluminium kit (untouched).
It comes with a carburation adjustment nozzle, a cold racing candle, carbon racing valves studied in the kit. Its piston is reinforced and worked in the kit, its head is truncated polished 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 hand-touched diagrams!
They will also appreciate the reinforced o-ring joint that avoids many well-known worries on this type of engine: flat aluminium joints that break. This kit also comes with a reinforced and greased needle cage. Noted the finishing of lateral transfers which leaves to be desired.
We recommend it with at least: reinforced crankshaft, 21mm carburation and settings, reinforced bearings, racing exhaust.
