Piaggio Vespa Crankcase Central Gasket PX80, PX125, PX150, Cosa125
The central gasket is fitted between both sides of the Vespa PX Crankcases. Smothering the gasket in grease before use will hopefully stop any small leaks that may occur between engine.
In the past, the gaskets haven't always fitted perfect, so cutting part of the gasket that overlaps inlets may need modifying.
