Description

Andrea Pinasco was one of the first mechanics who successfully tried to improve the performance of classic Vespa scooters, and his company Pinasco consequently became one of the household names for Vespa tuning. Carburetors, cylinders, exhausts, crankshafts - everything to make your vintage Vespa run better and faster.

Pinasco Cylinder Spacer / Gasket aluminium 1.5mm for Pinasco 177cc cylinder for Vespa Sprint 125 - 150cc, 1.5mm spacer for long-stroke crankshafts. Using a crankshaft with longer stroke means that the cylinder has to be slightly raised. This aluminium spacer can also be used as a template for aligning cylinder and crankcase.

Notes and Safety

Cylinder spacer

Cylinder spacers should only be used by experienced tuners who have enough know-how to understand the complex workings of an engine and implement the corresponding measures.

What is the benefit of a cylinder spacer?

A cylinder spacer may be necessary if you are using a long-stroke crankshaft, as the piston rises higher in the cylinder to increase displacement.

With a 2-stroke engine, however, you cannot simply raise the cylinder. Raising the cylinder will also increase port timingd, which will completely change engine behavior; it can also result in a significant loss of power at low engine speeds.

If you want to use a spacer, make sure that the crankshaft, connecting rod and cylinder are designed for it or are compatible.

Note: Cylinder spacers vary from engine to engine. Their thickness must be matched to the crankshaft and cylinder. Please also remember to order cylinder studs in the correct length.

Aluminium cylinders

Aluminium cylinders are more powerful than cast iron cylinders, but require more regular maintenance and must be combined with different components such as a reinforced crankshaft and a larger carburetor.

How to run in an aluminium cylinder?

Aluminium cylinders should be run in for about 200 kilometers , and you should use a fully synthetic engine oil.

Note: To ensure optimum performance and reliability, it is advisable to measure the squish clearance. Just have a look at our tutorial How to adjust squish clearance.
