Enlarging the cylinder bore will increase cc's in a 2 stroke and ci's ina 4 stroke.....
This is the diameter of the cylinder hole in the engine block for the pistons.
if the diameter of cylinder and stroke length of an I.C. engine is greater then the power output is more.

Cylinder diameter is the Bore.Bore is 73.0 mm (2.87401575 inches)Stroke is 77.4 mm (3.07424409 inches)
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 displacement of an engine can be altered by changing the bore (the diameter of the cylinders) or the stroke (the distance the piston travels within the cylinder). Increasing either the bore or the stroke will result in a larger displacement, which can enhance engine performance by allowing for more air and fuel to be combusted. Additionally, modifications to the engine design, such as adding more cylinders, can also increase displacement.
Boring out the cylinders enables you to put larger diameter pistons in the block. Having a larger diameter cylinder means that the displacement of the engine increases. This increase can provide greater horsepower. Boring out a worn-out engine a few thousandths of an inch can square up the bore of the cylinder and breath new life into a worn out engine by restoring its compression. Good compression will have greater effect on improving the performance than the slight gain in displacement.
