Straight from the experience of MVT and AGP (Alain Godou Production) in competition, here is the G2A high engine from MVT . This high engine has a stud center distance of 43X50mm like the original MBK 51 cylinders and it is designed for a 41.8mm stroke with 85mm connecting rod like the original, it is therefore to be installed on prepared original crankcases , vintage POLINI , MALOSSI EUROPE, EUROCILINDRO crankcases... This kit has a huge booster exhaust, a one-piece cylinder head with a frustoconical combustion chamber with a polished finish. A DEC of 2mm is applied for a good hold and a good firewall of the O-ring. Of 6 intake lights. The architecture of the very massive cylinder leaves room for the work of a preparer, for fixing an exhaust 2 screws, 3 screws... We can model the whole thing as we wish. This competition set has very large diagrams and a very high compression ratio, it must be accompanied by an engine configuration which follows, exhaust, ignition, large carburetion, variation being capable of exploiting the 11,500 / 14 500 rpm power...
