My warrior pulls to the right real bad. As soon as i let go of the handle bars they turn sharp to the right. The alignment is fine and both tires have an equal amount of air. Just replace both front wheel bearrings. Cant tell if the steering stem is bent. If it is it isnt very noticable. How bad does it have to be bent to effect the steering that bad? Would bad steering stem bearing cause this?

 

Rear tire pressure/alignment can result in poor steering as well. I'd check both. The rear axle chain adjustment on these quads is a pretty poor design, misalignment can occur pretty easy. If everything up front seems fine and is new, then it should be fine. My only other guess is a bent frame.
If everything is aligned and in proper working condition, you should be able to go along in 6th gear without any hands on the bars and it should track straight.

You are testing it on a flat surface aren't you? Most roadways are not flat.

FYI: a bent steering stem is usually just bent along it's axis. Think of it like a straw. You can bend the top and it "pinches" on itself. What you describe is what I would consider "twisting" the stem, similar to a torsion bar. I don't think you or I could twist it enough to cause permanent deformation in the stem itself (meaning that it twists so far it doesn't spring back), so I doubt that is the condition.

As far as the bearing is concerned, I haven't heard of that premateurly wearing out on the Warrior. It could be bad, which would cause some slop in the stem, but if your condition is as bad as you describe it, I doubt the bearing is the problem. Again, if it is that bad, the problem should be kinda obvious as to what it is. Honestly, no matter what you do, it will probably never be totally aligned correctly.
