There is a flaw in your math.


Stroke x bore = length x length which is not a volume!

You cannot divide CC volume (length pwr3 by length pwr 2 and obtain CR, a dimensionless number.


CR = (cylinder volume + CC. Volume) ÷ CC Volume = (850/2 + 51.6)/51.6 = 9.23


Since an 850 is actually an 830, the above formula becomes (830/2 + 51.6)/ 51.6 = 9.04
