I would try turning out the pilot screw out until it clears up a bit....up to 3 turns out from a fully seated position. If you need more than that, then I would get the next bigger jet and start again from 1/2 turn out and until you get 'er dialed in. Only turn it about 1/8 turn at a time...a little at a time will do a lot
I have a 2001 Yamaha Warrior and a 2001 Polaris Trailblazer. The Blazer is pretty well wasted, but one day I may fix it. I use them for trailriding. I like the mud and jumping the most. Jumping into the mud is like a little slice of Heaven for me.
