I have a mint 1980 Yamaha 440 ss and a mint 1991 Polaris indy trail 488. Both sleds are very clean and run great. plus I will throw in a 1989 Yamaha exciter 570 for a parts sled or a project sled. I am pretty sure it needs a set of pistons and rings. But almost all the parts on the exciter will fit the 440ss. Looking to trade for a newer, faster sled
