But on the left side of engine is a cover that covers the small sprocket on engine which he would have to cut a opening on the bottom of the cover for chain to go down to the left peddal axle.
i may just mount the engine up higher on the frame, so the angles will lign up, i don't like the idea of cutting it.

And to to those giving me **** about how it wont have pedals, the first gas bike i had i installed with pedals, and the way it was intended, but the torque from the motor to the rear wheel was too great and ended up warping the spokes, so a solution i made was to get a disc brake wheel/ hub, and mount the sprocket to the spot where the rotor would go, by drilling out holes... that has worked for about a year now... the bike has failed on my a few times, but i always carry a tool pack with me, with the essential bike tools, allen keys, wrenches, ducting tape, extra fuel line. A year later now, the gas bike runs just as good as it did..

I was doing all this with a budget, and parts i had accesble.

im now undergoing a new project converting a chopper bike, i wont do this method, although i will have a pretty interesting build.

Im using parts from a 1970's honda 50cc moped i got my hands on, mainly the rear wheel, i checked it out and it turns out the rear wheel's sprocket is the same size teeth as the gas bikes, so i will be able to use it. it has a built in drum break, witch works really well, so that will help to break the bike.

I already modified the frame to accommodate the larger rear axle size, i am now undergoing painting of the chopper bikes frame, i choose a "Pumpkin orange" looks pretty good so far.

The plan is to take parts from the moped and attach it to the chopper, Ie generator, headlight, horn.

i'll take photos
