Bore is how wide the cylinder is, measured from side to side at the widest point.
Stroke is how far the piston pushes, measured from when it's furthest from the top of the cylinder to where it's the closest.

Formula for displacement per cylinder is:
Stroke^squared * Bore * .7845
Then multiply by the number of cylinders for the total motor displacement.

Went through that in school, got bored enough to write myself a calculator program to do it for me... lol
