A combination of additional power, good tires, and just knowing how work the machine to your advantage will all help get the front end up. The warrior's weight balance is pretty far forward compared to most sport quads because of where the heavy engine is positioned, so you're never going to pull a wheelie as effortlessly as a 400ex. In my opinion, that's a good thing though, because a wheelie where you don't want one, such as while you're heading towards a tree, can be a bad thing. Another thing that limits a stock warrior with wheelies is the throttle response of the stock carb. With my edelbrock you can give the throttle a hard jab and throw your weight back and the front will come up in 2nd gear at just about any speed or surface. Not cheap though. Mostly though, get used to timing your movements so you throw your weight back right as the engine starts pulling, not when you actually hit the throttle. The more you lean back the easier the front end will come up, so even the right handlebars can help to a certain extent.
