Re: New here from South Lake Tahoe, CA
Well I would figure an 67cc will be faster than a 49cc. (no such thing as an 80cc, that I know of). I like the slightly more torque of the "70cc" (67cc), but the 50cc revs faster, so the difference is not L4 vs. V12 difference.
Can't help you with kali laws, but, well er, environmental types HATE 2 strokes, with a PASSION.
