I had a guy drop off a yamaha 400 in front of my garage, because he liked how I bobbed a xs650 last summer. but theres no paper work and the dude said he got it from a scrap yard. The side covers and some small stuff is gone, but its in way better shape than the 650 I did. So anyway I need help iding the # 3F8-029809. Any help would be greatly apreciated. 1rarebru
