Cylinder
In Turkish: Silindir
In short
The cylinder is the part of the engine in which the piston moves and combustion takes place.
On small motorcycles and scooters the cylinder is usually a separate casting that sits on the crankcase. As a spare part it is mostly sold as a cylinder kit: cylinder, piston, rings, gudgeon pin and gaskets.
- Vertical scoring and ovality in the bore cause compression loss and oil burning.
- Light wear can be honed out; heavier wear needs a rebore and an oversize piston.
- "Big bore" performance kits increase engine capacity and need care regarding registration and roadworthiness rules.
