The cylinder fits 125-150cc engines built between 1953-1959 with two overcurrent channels in the engine housing. The Pinasco is based on the 57mm stroke of the 150cc models. This kit includes a crankshaft with 57mm stroke which is mandatory for 125cc engines with only 54mm stroke anyway. However, due to the almost doubled power, we also recommend using a new crankshaft for all 150cc models. This kit is therefore the ideal complete solution. The original intake manifold can still be used and the Polini CP19 carburetor is recommended. For more power, the intake manifold 3331742 can be combined with a Polini CP23 carburettor.
In the download area you can see a diagram of the cylinder with a prototype of the BGM BigBox Touring and a CP23 carburetor. The high early torque (14.6 Nm at only 3600 rpm) and the impressive power of 10.4 hp at 6100 rpm are clearly visible.
Scope of delivery
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 engine housing accordingly (spindle approx. 0.5 to 1 mm deeper).
Note: The stud bolts required for fastening the intake manifold are not included in the set. Please order these separately (see accessories).
