I'm thinking about a new atv. My Polaris 325 Magnum is 8 years old and has been a great machine. It's done all I've asked of it with zero problems but it tends to run hot if I try to use it as a tractor to disk small food plots. It's air cooled. I'm thinking of something a little bigger thats liquid cooled. I really like Polaris and am looking at maybe a Sportsman 500. Any suggestions or recommendations of other brands?
