The liquid 50cc Polini kit is the replica of the G2 that would run on circuit then. This cylinder is relatively efficient despite rather low diagrams, this low diagrams also allow him to be able to ride on a small configuration (type of pot + 15mm carburetor). This kit if it is accompanied dévoileras a pretty good power. The cylinder is cast in GILARDONI and therefore good, the bore diameter of 40,2mm, the exhaust is a very large W model which opens the light to the maximum in the width without risking the 'segment of uprooting.
Apart from this, admission is 6 transfers to the base are large transfers designed so you need to prepare your casings to align the cylinder transfers. Polini worked cooling the cylinder provides excellent cooling but also look out of the common. The piston is a model POLINI (ASSO not like the 70cc) in mono segment to allow you the highest regimes, this piston is slightly prepared on the rear for improved scanning and high silicon content and has nipples side.
The cylinder head is a model high compression blasted hemispherical room (we would have preferred a polished finish). The cylinder head has a clamping 1.3kg offers a compression ratio of 9.9: 1. In short this kit is one of the last true racing liquid remains on the market (6 transfers, mono segment, exhaust W) and a preparer by increasing its diagrams be able to get out phenomenal power. At such a price there shalt act as a very good replacement cylinder lined with a huge performance gain compared to a source.
We advise to accompany this kit with at least: expansion box, 15mm carburetor (more if you summers equipped ... Everything is relative)
