I took a 87 Polaris 450 or something like that last year out of a guys barn, paid $50. Hadn't been started since early 2000s and was a mouse hotel. Tore out everything, pressure washed it, cleaned the carb and tanks, hooked it all up and with a couple little caps from ebay for the carb she ran! It was amazing. Sold her for $500 after riding it for a couple weeks. Those old Polaris sleds are awesome.
