Re: Theoretical way to make a cheap 79cc friction drive.
A 3 1/2" clutch housing would get you about 42 mph at 4000 rpm if the bearings can take the stress and you can get traction on the tire. You'd probably want something bigger than the 79cc to go fast.
A small clutch that could handle 3 to 5 hp and it might be doable.
It definitely obeys the KISS principle, keeping it simple.
