The famous and well known liquid kit POLINI for engine motobecane av10 (mbk 51 magnum ...). This is one of the few kits available for motor liquid on the market, this model is the sport in W, not the G2 which is no longer manufactured. The cylinder is the same diameter as the original in Ø39mm, it is aluminum and has 6 + 1 transfers exhaust W which allows a maximum aperture width without risking tearing the segment.
This high quality cylinder is manufactured in GILARDONI and chrome treated silicon, we also appreciated the architecture of the channels is excellent. Level base, large transfers are present, so you need to align your casings with these, they are not necessarily useful in this unprepared kit because it has very little diagrams must admit! You can save a lot of power by enhancing the charts at least 10 ° to 20 ° to the exhaust while pheasant track admission. The piston comes with this kit is a very good model has high silicon content, mono segment to allow the highest regimes, piston also has a small preparation for improved scanning, lateral nipples to avoid heaters side and scrubs.
The cylinder head is a high-compression model blasted hemispherical room, so we regret too low diagrams, an unpolished room and a non-chrome segment / convex and a rather fragile processing (preparation example) apart from that this kit preserves large assets such as real transfers 6 (not blind), exhaust W, exhaust mono segment, the aluminum material ... This kit is therefore a very good very torquey model able to reach very high speeds with a good motor preparation (has to do with professional or expert, the W and the treatment requires care and time).
