I'm taking my 06 YZF450 to St Anthony's dunes for the first time. I'm a recently converted 2 stroke rider (and yes the YZF is everything I imagined). I usually bumped the main jet up 2 sizes and the needle one step richer on my 2 stroke. What's the usual jetting increase for big sand dunes? Up one on the main? Two? I'm currently running a 45 pilot, stock needle & clip, 165 main. Appreciate the guidance.
