50cc liquid aluminum kit with MVT COMPETITION G3 cylinder head (103, 51, OPEN, G3...)

Straight from the experience of MVT and AGP (Alain Godou Production) in competition, here is the high engine G3 from MVT . Please note, this high engine has a stud center distance of 52X52mm, so it must be installed on special casings such as the MVT G3 or MVT G4! It is designed for a stroke of 39.7mm, so it must be installed in combination with a crankshaft with a stroke of 39.7mm and a 85mm connecting rod like the BIDALOT of the period or the MVT of today (reference VI41). This kit has a huge booster exhaust, a one-piece cylinder head with a polished finish frustoconical combustion chamber. 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, the fixing of an exhaust 2 screws, 3 screws... We can model the whole 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 12,500 / 15 500 rpm power...
