Just put a BGF 2 cycle (ebay $129) on a new schwinn delmar ($99 walmart) Learned a few thing from the forum before i started the build. Machined the sprocket to fit over grease cover on rear hub, screwed the tensioner to frame to keep it from going into the spokes, made front motor mount, deburred casting slag from intake and matched it to the cylinder. Its runnig great and im havin a blast with it. Thanks for the great site, saves a first time builder alot of problems. Im ready to try a bobber or flat track racer next.
