Well took my car to a shop today and the guy getting his oil changed said he had one he would sell me for 50 he got at a storage action it has a part or two out but all was there and I guess its a 80s Yamaha moto-4 (I think its a 85) not sure on the motor size going to look at it all when I get it home know its bigger then a 80 now what do you guys think?
