what is the true size of an "80"cc chinese motor?

[jake]

ive been wandering, since everybody seems to say differently, what is the true displacement of my ebay 80cc? an if you have measured, what is the bore and stroke? i would measure it, but it is being broken in and i don't want to take it apart yet.

I've measured 3 of them, Dax, Kings, Tiger. All are 66cc.

Just keep in mind Dax says his are 70cc not 80cc.
