How to Install a cylinder on a scooter, motorcycle or moped
The cylinder or cylinder kit is the heart of the engine on scooters, motorcycles and mopeds. It consists of a cylinder, a piston with piston ring(s), a cylinder head and gaskets needed for installation.
The service life of a cylinder depends on whether it has been fitted correctly.
Cast iron cylinders
Cast iron cylinders are more robust and reliable than aluminium cylinders and require less maintenance. Cast iron kits, however, yield less power. To improve output, you can add performance enhancing components such as a reinforced crankshaft, a larger carburetor or even a tuning exhaust.
How to run in a cast iron cylinder?
Cast iron cylinders should be run in between 300 and 500 kilometers, you should use high quality semi-synthetic engine oil.
