Cylinder -POLINI 70 cc Big Evolution (85mm con-rod)- Piaggio LC 2-stroke
Part no.:
P1400207
Description
The Polini BIG EVOLUTION cylinder kits for Piaggio and Minarelli engines are available in three sizes:
These are the big brothers of the Polini Evolution 3 cylinder. Five fat spillways and a T-shaped outlet form the basic layout of the cylinder. The performance is of course even more brutal compared to the 70 cc version and the right one for every acceleration race.
The workmanship is typical Polini at the very best level.
In order to be able to install the BIG EVOLUTION kits, the engine case has to be spindled. The cylinder base is thicker due to the huge bore in the outer diameter. So the crankcase has to be brought to the right diameter.
If you want to build the longstroke shaft you also have to bring the crankcase to the right diameter.
