For as much as I am going to use it I don’t think I necessarily need fuel injection. I want to keep it under 2k.I would skip the 90s and look at early 2000's fuel injected Arctic Cats, like a ZR or ZL in the 500 to 600 range.
I like Polaris sleds as well, but in those days, they were pretty much all carbureted, and F that noise.
