you would have to pull the carbs and see exactly whats in there as far as main jets, pilot jets, and the needle setting.
guessing minnesota to be a low level altitude, this would be standard jetting as delivered from the factory for elevations of 300'-2000':
pilot jet: 52.5
jet needle clip: #3
air screw: 1 1/8 turns out.
compare and see what you have and where its at. you also need to consider clutching. typically the clutch will be loaded lighter for higher elevation along with different springs in the primary. secondary settings will be different as well.
worry first about the carbs. if you run elevation jetting at lower altitudes you are subjecting yourself to a lean condition.
This has me worried... all of my 3 VMAX 600's were set at 2.25 turns out. We checked them, cleaned them out, and reset to 2.25 turns out.
We are ride 200-1000ft elevation...
The front air jets were clogged shut in these sleds... they are clean now, and idle much more evenly. But I did notice afterwards that instead if just revving a bit and idling down... it wanted to die when it idled down. A quick blip brought it back and evened the idle.
You are saying just over one turn out is factory?
