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. This kit includes a crankshaft with 57mm stroke which is mandatory for 125cc engines with only 54mm stroke anyway. Due to the nearly doubled power we recommend to use a new crankshaft in all cases, even for the 150cc models. Therefore this kit is the ideal all-in-one solution.
The original intake manifold can be reused and the Polini CP19 carburettor is recommended. For more power, the 3331742 intake manifold 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 as well as a CP23 carburettor. The high early torque (14,6Nm at only 3600rpm) and the remarkable power of 10,4HP at 6100rpm.

Please note: VM/VN1/ACMA/Motovespa engine housings often have a spindle dimension in the engine housing that is not deep enough. In this case, please rework the motor housing accordingly (approx. 0.5 to 1mm deeper spindles).
Note: The stud bolts required for fastening the intake manifold are not included in the set. Please order them separately (see accessories).
