compression ratio

[TrikerR]

hay guys.

today i was at the local honda dealer rummaging around in there parts department, and i found dusty little box contaning a high compression big bore piston for my 110, and even better the guy gave it to me.
anyhow, i was just wondering if there some magical equation to work out the compression ratio of a machine.

i dont know about the ratio, but want to sell it? :D

you probably have to do something with the combusion chamber, piston?

yea, i found a calculator for it on theinternet. and no, im definately not selling it...ive been looking for one of these for a year.
