I bought this for a project blaster of mine but I just do not have time to finish it or the money. It needs a rebuild of the top end I do not know what size piston or bore it had but the local Yamaha shop said if needed it could be sleeved. I can email pics this weekend if anyone is interested. Best offer accepted plus cost of shipping. or local pick up. email seprowling52271 @ gmail.com or daytime only call 919 278 6089 my work cell number if no answer call back
