hello,
no i'm not building a motored bike, but i am using a motored bike engine, i plan to buy a "happy time" engine as you call them. i will be changing the gearing from what most these kits use, and to get it right i need to know what the internal gear reduction is on the standard happy time engine, i can guess its about 4:1 but i can't be sure. i hope someone can help! thanks!
p.s. if your curious, i'm building this,
