Engine lets say honda gx35 or subaru robin eho35
or even the gx31
Ratio's Ive seen ratio's range from 16:1 to 22:1 on 26 " rims
terrain say flat slight inclines
should friction drive run lower ratios compared to chain or belt drive
trial by error ends up costing a lot of time,money and effort , has anyone done the hard work?
any response will be very appreciated
