Re: Finding engine capacity

(3.1416 X radius x radius) X stroke X no of cylinders

where radius = bore / 2

That will give you the litre capacity, to get cubic inch times that by 0.061

Re: Finding engine capacity

The easiest way that I know is:
Bore X Bore X Stroke X .7854 X Number of cylinders
Hope this helps.
