Well i finally decided to purchase a engine kit for a beach cruiser. I found the cruiser on facebook marketplace for $25, and it was delivered. turned out to be a brand new bike. As for the engine kit i went with a zeda 80 firestorm. I had one issue with the exhaust. it would not fit around the bikes front downtube. Tryed the motor adapter, didnt like it. ended up finally with a ball peen hammer.it`s there and not touching the frame now. i have not started it yet and still needs the chain on, besides its like 19 f outside. but i plan to get the flexpipe exhaust i guess. also gonna have to take some width out of the handlebars, damn. The wiring i`m hoping is good, it was all plug in play,ha i didnt ground to the frame. Is that necessary? and from where?
