Cylinder Piaggio/Vespa 4-stroke 2-valve 80cc 49mm Polini

When does a cylinder need to be replaced?

A cylinder of Polini, for example, is an essential part of your Piaggio 4-stroke scooter. A cylinder needs replacement when there is a scratch or bumper in the wall, so the Piaggio 4-stroke cylinder loses compression. Compression is the compression of the fuel/air mixture in the cylinder. With no or hardly any compression, the engine of your Piaggio 4-stroke scooter will no longer start or drive badly. A scratch or bumper is a palpable unevenness in the cylinder wall. As a result, if you replace only the piston; this new piston can also immediately damage your Piaggio 4-stroke scooter! If a Piaggio 4-stroke scooter is poorly adjusted or has too little oil, the wear and tear of your Polini 80 cc cylinder is a lot greater.
