I ahve that same bike. As said before it is a cat eye pocket bike. I cut all of the extrac metal tabs off. It used to have a body like a crotch rocket. It had a horn, blinkers front and back, brake lights and headlights. It also had a remote start. I removed the batter box and everything that held the body on. Now it looks MUCH cleaner. Also, i tried to put a 5hp flathead briggs in it, its too tall. Its been done witht eh clone engines witht the gas tank removed. Give it a shot. can you tell me what size chain it was? Is it #35?
