Re: 49ccvs 80cc dimensions?
I believe the jug's a little roomier on a 66cc. Outside of that, you can't tell by looking. Theoretically, and hypothetically, if one wished to operate a larger cc engine in a state where it wasn't permitted to operate by law, one could remove any labeling identifying it as a larger cc engine and replace it with labeling identifying it as a smaller cc engine. I cannot in good conscience advocate such an action because, you must understand, in some states that practice would be a minor criminal act.
