When you say overbore by 50 thoug .... do you mean 50 thousandths of a 'mm' or of an inch? The spec. page you gave gives the bore/stroke in mm but when people say '50 thou' they usually mean 50/1000 of an inch.
Anhow, when you've figured that out the formula for capacity is:
(bore/2) x (bore/2) x pi x stroke x number of cylinders.
Or, to put it another way: half-bore-squared x pi x length x num. cylinders
(pi is c. 3.14159 ...)
Enjoy the calcs!
