Someone here had asked me about figureing compression. I will explain this the best i can.
Volume of a cylinder:
(Pie (Pi?) x radius squared) x height (stroke)
FYI--cubic inches x 16.383 = cubic centimeters
For example: Say the stroke is 3.25 " , radius 2.020. 3.25 x 3.14 x 2.020 squared = 40.23
40.23 x 16.383 = 659.1 cubic cent. Let's pretend the combustion chamber is 66 cc.
659.1 divided by 66 equals 9.98. So you end up with 10-1 compression.
Hope this helps.
