XT250 Carb

I've got a 2008 XT250 and I live at 6500 ft. The bike seems really rich and the condition gets worse when I go over passes sometimes up to 8000 or 9000 ft. I pulled the air cleaner out to see if it made any difference and it made a noticeable difference. The bike ran much better.

When I look in the parts book they only list 1 jet size for XT250s. I've ordered a jet kit off ebay but don't really know what it consists of.

Does anyone have experience rejetting one of these carbs? Any suggestions on sizes, main jet only or main and pilot both? Lower the needle?

Someone give me some guidance here.
