Yes. Boring is simply the process of removing material from the cylinder bore, usually measured in hundredths of inches; .010, .020, etc.
However, there are downsides. Stock engine blocks often don't have sufficient material and boring may weaken the cylinder walls. Boring will also require new oversized pistons and rings.
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.
I assume you mean engine displacement? To calculate engine displacement, use this formula: Bore x bore x stroke x .7854 x number of cylinders.
this is the diameter of the cylinder hole in the engine block for the piston

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.
For balance.
Oversquare
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.
The engine has been rebuilt and someone didn't want to bore all of the cylinders and replace all of the pistons. Actually come to find out, all saturn 1.9L engines are built this way in purpose due to problems with heat build up in cylinder 4. upon testing the #4 piston would seize up in the block once the engine hit 220 degrese. Re-boreing the #4 cylinder wall an extra .010 fixed the problem.
If Measuring in mm, ( Bore x Bore x Stroke x .7854 ) / 1000 = cc's
