I just purchased my first motorized bike with a 66 skyhawk motor. I'm not use to the way they ride and was wondering if its alright for it to be kind of jerky with running at low speeds. The engine and drive train is noisy but seems to be working alright. I just notice the somewhat rough ride. I first thought it was my front wheel being out of round but when I press in the clutch it smooth's out. I thought it might be just the way a small engine tries to sync with the drive train that makes it jerky?? I also notice that I need to sometimes add a little choke so help get it up to top speeds, sometimes not. Thanks
