I just did this yesterday, with no prior experience.
Make sure you have an impact screwdriver. It's essentially a big handle with a screwdriver tip that you hit with a hammer. It's necessary for all brass screw applications. If you don't have one, buy one otherwise you're going to waste time with the over torque brass screws.
(all left/right directions are based on you facing the front of your atv)
1. remove the plastic on the right side that is adjacent to the gas tank.
2. on the right side, near where you knee would be, there is a black box that uses 1 bolt to keep it attached to the frame, remove the bolt. This black box gets in the way when you try to tilt the carb (it did for me at least)
3. stand on the left side of your ATV
4. Your carburetor has 2 rubber boots held on it with metal bands, loosen the bands so you can twist the carburetor. The rubber boots might stick a bit.
4. tilt the top of the carb away from you while pulling the bottom towards you.
5. You may need to disconnect some hoses that interfere (you'll know when you see it)
6. On the bottom of your carb, there are 4 brass screws, loosen them with the impact screwdriver. fully remove the screws.
7. Pull the bottom plate away from the carb, don't lose the gasket (you'll see it)
8. You should now see a brass bowl type thing with a screw in the center witha hole through it. That's your main jet. Unscrew the bowl-thing.

9. Remove the jet from the bowl.
Tada!
I would have taken pictures, but I wasted too much time with the brass screws.
You CAN replace brass screws with steel, BUT YOU MUST USE ANTI-SEIZE COMPOUND & ENSURE IT GETS ON ALL THE THREADS.[/url]
