Cylinder -PINASCO 160 ccm MEMBRANEINLASS, Wideframe, Faro Basso, Ø=60mm, stroke=57mm- Vespa 1953-1959, VM, VN, ACMA, VB1T, VGL1T, VL1T

Pinasco 160cc cylinder with reed valve for Wideframe Vespa

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

The cylinder fits 125-150cc engines built between 1953 and 1959 with two overcurrent channels in the engine housing. The Pinasco is based on the 57 mm stroke of the 150cc models, 125cc engines with 54 mm stroke require the shaft of the 150cc models. Due to the more than doubled power, we recommend using a new crankshaft in all cases (Stoffis, Pinasco etc., see accessories). The cylinder has a diaphragm-controlled intake compared to the original. This means that it is independent of the symmetrical piston control and can draw in mixture at any time if required. This improves the rev range as well as the driveability from the lower rev range. In addition to the complete cylinder, the set also includes the intake manifold and connecting rubber.

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