Description

Cylinder -PINASCO 75ccm Sport- for the Vespa PK50 automatic. Pinasco is the only manufacturer who offers a cylinder for the PK/XL Automatic. Thanks to the 47mm bore, 75ccm displacement is available. This increase in displacement in combination with a nice port layout provides a much better pulling power and even driving in pairs is mastered. The power of the cylinder is almost 3.8KW and speeds of up to 70km/h take even longer distances their fright. The pre-ignition value should be set to 18°. The cylinder and the piston kit are included. The original cylinder head can be kept, the piston supplied is modified accordingly (spark plug NGK B9ES Art. No. 3300009).
Pinasco recommends additionally chamfering the inner sealing edge to the bore diameter of the new cylinder (Ø 47mm). According to Pinasco, the main nozzle should be selected four numbers larger (original mostly 74, i.e. a 78 with M6 thread)

Attention: Pinasco does not supply a foot seal and no exhaust gasket! Replace the existing spark plug with an NGK B9ES or Bosch W2CC.
