Re: will this fit an 80cc/66cc kit ?
I bolted a spare kickstand to my chain tensioner bolt(straight with the frame, not up and down) and i hose clamped the kickstand to the frame. Tensioner does not move at all and will not need adjustment.
You could also use a metal bracket. I do not believe in drilling into the very small part of the frame, i prefer to use clamps which does not weaken the frame as much if at all.
