I have a DJ kit what main jets should I use

I have put in 25 pilots also
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!

mattschroeder61 Hey just wanted to share how i adjusted my air fule mixture screw on my quad i got it from menards it was 17 bucks it came with red plastic on the sides but i pulled it off so it would fit between the motor and bowls. Just slide in a flat head bit and use a nut driver to spin it.

At which throttle position do you experience the bogging.

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.
