wtf are you talking about, all the sled manufactured except for yamaha make two strokes, there will always be two strokes in snowmobiling, you ding dong. And by the way, this can is why land gets closed for trails, this is bloody f-ing annoying
A new slead with al its fuel injektion and elektronics will never scream like a carbureted two stroke 440 rev or 440 snow pro. And next generation of sleds will probably have an electric engine.
