The plug on the bottom of the float bowl will give you access to the main jet. You will need to be richer, so make sure you go up plenty and work your way down.
The jets are fixed size, so you have to change them, they are not adjustable. They Mikuni Hex jets and your local snowmobile dealer should carry them, except for Yamaha dealers because Yamaha used a different style of jet in their Mikuni carbs.Leaner? I live in central minnesota if that helps. Do I have to change the jets of just adjust the ones there?
