I made the mistake of buying a 2016 Pro Rmk 600 instead of an 800, my buddy that I rode with mostly had a 600 at the time also. He totaled that sled and then bought a new 800, so I am looking to get a little more low to midrange, what I am thinking is Kurts Gear Down Kit, has anyone put one of these on a 600, or other ideas on that, I dont want to do motor work.
