Shelpi. here ya go .Bore x bore x .7854 x stroke x number of cylinders.  The bore size MUST ALWAYS be first in this equation , The figure of . (that's point)   .7854 is a constant in all cc calculations.

In your case that's  62 x 62 x .7854 x 54 x 2 = 326cc

Current engine in my 754 being 67 x 67 x .7854 x 65 x 4 = 916cc

Cheers  Lucky front wheel from me ???? :D Suppose it did reach the finish line before everything else!!! ;D

I may not agree with what you have to say, but I'll defend to the death your right to say it.
