Needs some info.I just bought the wife a 07 600 ho 155 and was wondering what to do with the jetting/clutching/gearing ride 3000'to6000'.Its all stock other than a airhorn.Thanks

The stock clutching/gearing worked OK with my 144"....The stock 280 mains and #1 needle position were also OK for 3500 8000'....All I had to do was leanout the pilot circuit with a .9 PAJ and turn in the fuel screw to 1/2 turn out....SLP can and gutted airbox

On mine (back up sled) have AATAC for jetting, can't remember the baseline jet but basically was right on factory jetting chart for altitude and -20C. .9PAJ and 40 pilot jets really cleaned up the bottom end. Went to 19/42 gearing, stock clutching (primary weights as per chart as well).
Works real nice now, strong for a 600. Mine's a 155"
