I don't know why but whenever i wheelie my warrior steers left what could it be?

 

did you check you air pressure in your tires. also make sure your chain adjustments are even, your axle might be alittle bit out of square with the rest of your quad

 

yeah tire pressure is even i was thinking it could be the rim i don't think its the axle. When i am going top speed it shakes so i think it might be the right rim.
The rim doesn't wobble when going slow but when i go fast it does but when i do wheelies i go slow so why does it steer to the left?

 

the chain is on the left, therefore it very slightly pulls the axle in to the left, if your hubs are loose that will also do it, and if your tire has more tread on 1 side that will also do it, and if your swingarm bearings are worn. mine does the same crap so i gotta lean my **** to the left hand side when doing long wheelies most the time

 

More than likely it's the tire pressure is still not perfect. It has to be spot-on. Let some air out of the right rear tire until it wheelies straight, then measure the air pressure to see if it's even. If it wheelies straight with uneven tire pressure, then something is out of wack that was mentioned above. If you can steer slightly on a wheelie by leaning to the side of the direction you want to go in. You can even steer around slight curves by leaning and having very low air pressure in your rear tires.
