A cylinder parent bore refers to the internal diameter of a cylinder, specifically the area that houses the piston or piston assembly. It is a critical measurement in engine design, as it affects the engine's displacement, performance, and efficiency. Ensuring the correct parent bore size is essential for maintaining proper engine function and compatibility with the corresponding piston components.
This is the diameter of the cylinder hole in the engine block for the pistons.

Generally the nominal diameter of cylinder bore is kept little smaller at cylinder head than at the bottom. The engine head will be generally heat and it tends to expand for these high temperatures. To prevent the bore diameter at head to exceed diameter at bottom,piston engine bore is ground with a slight choke.
The bore of a cylinder is the diameter of the cylinder in an engine. It is directly related to the displacement of the engine, which affects the power output. A larger bore can increase the displacement, allowing for more air and fuel mixture to enter the cylinder during the power stroke, resulting in higher power output.
Enlarging the cylinder bore will increase cc's in a 2 stroke and ci's ina 4 stroke.....

The bore size refers to the diameter of the cylinder in which the piston moves, not the piston itself. It is a critical specification in engine design, as it impacts the engine's displacement and performance. A larger bore typically allows for a bigger piston, which can increase an engine's power output.
The bore refers to the Inside diameter of the cylinder. The Piston will be nearly the same diameter, with the piston rings making up the difference. Convert the bore to area by multiplying by pi and dividing by four, and multiply by the stroke and the number of cylinders and you have the volume displacement of the engine.
A Cylinder bore has no choke at all.
I assume you mean engine displacement? To calculate engine displacement, use this formula: Bore x bore x stroke x .7854 x number of cylinders.
