I turned the mix screws on my carb out only one turn and it seems to be running just fine. Does anyone think I should reset them out to three turns? Thought I might run into trouble when the weather gets cold. Is there any way to adjust them while still on quad. Can't seem to get in there to well with a short screwdriver.

Id recommend these:

They are offered in various colors. Here's a pic of them installed on my carbs. They're able to be adjusted easily with long-nose pliers.

I have the same ATV
I run stock lid, snorkel removed.
#25 pilots, Mikuni 150 left, 155 right.
Extended fuel screws @ 1-3/4 to 2 turns out.
I would cover ur holes in lid and remove the snorkel in front of the airbox lid, and run the DJ equivalent of Mikuni 150 & 155 mains.
It will open ur eyes!
I also have aftermarket needles set in 4th slot down from the top notch.
Ur altitude is the same as mine.
Hope this works for ya!
