what does a gasket do?

There are many different types of gaskets or gasket sets in an engine, e.g. cylinder gaskets, intake gaskets, oil seals, crankcase gaskets, exhaust gaskets, carburetor gaskets or engine gasket sets. They all have the same function: to prevent leakage between components.

When and why should you change an engine gasket?

When servicing your two-wheeler or noticing leaking fluids, be sure to follow this one important rule: Always replace an old gasket with a new gasket.
Damaged or worn gaskets can no longer do their job properly, the parts that have to be sealed are no longer adequately sealed, which can lead to serious follow-up damages.

Before you install a new gasket, you must thoroughly clean and degrease the sealing surface.

You can also use silicone sealant as an alternative to paper or metal gaskets in some cases. But beware, O-rings and oil seals cannot be replaced by sealant.

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.
