Cylinder assembly for Honda AF scooters. This is the block in which the piston moves: the cylinder walls define the combustion chamber and carry heat away.
Replacement is needed if the walls are worn or scored, compression drops, there is knocking, or oil consumption is high. The tuning version is designed for higher output, so the carburetor and exhaust may need to be adjusted. The number 48.00 in the name is the cylinder diameter in mm.
- Before assembly, clean and inspect the mating surfaces.
- Lubricate the moving parts with engine oil and break in the engine at moderate rpm.
