Cylinder -PINASCO 160cc REED VALVE, Wideframe, Rod models, Ø=60mm, stroke=57mm- Vespa 1953-1959, VM, VN, ACMA, VB1T, VGL1T, VL1T molto in saldo

Tuning cylinder with diaphragm inlet for Vespa Wideframe: VM/VN/VL/VB/Acma/Motovespa/VGL1

The cylinder fits 125-150ccm engines built between 1953-1959 with two overflow ports in the engine housing. The Pinasco is based on the 57mm stroke of the 150cc models, 125cc engines with 54mm stroke require the shaft of the 150cc models. Because of the more than doubled power we recommend to use a new crankshaft in all cases (Stoffis, Pinasco etc., see accessories). The cylinder has, compared to an original one, a diaphragm controlled inlet. Thus it is independent of the symmetrical piston control and can suck in mixture at any time if necessary. This improves the speed range as well as the driveability from the lower speed range. The set includes the complete cylinder as well as the intake manifold and the connecting rubber.

Please note:VM/VN1/ACMA/Motovespa motor housings often do not have a sufficiently deep spindle dimension in the motor housing. In this case, please rework the motor housing accordingly (spindles approx. 0.5 to 1mm deeper).
