Hello, I just picked up an older Yamaha 80 for my daughter. Im not sure what it is,and would like to keep it so Im posting up here for support.I will try to load a pic, but here is what I have as far as info on the bike. The bike says "80" on exhaust pipe Numbers on bike and motor say "367-000816" Its has a torn sticker on injector tank(?) says "Torque Induction" Numbers on Exhaust pipe say = Yamaha Krizman Sparkarrester Model KS-250 Approved U.S. Forest Service Any help identifying the bike would be greatly appreciated
