ok i am planning on buying a 400ex, predator, or raptor660 at the end of this
summer. but for now i have a warrior, my dad and i are working on it, and
i wanted to know how to add some good performance for not that much money. So you know what things to tell me to add ill tell you what i have on it.
port and polished head and bored to 360cc and 22" rear tires.

 

If your upgrading at the end of the summer most anything you do will be a waste of money. If your gonna do something I would go with an aftermarket exhaust because it will make the quad look better and maybe help resale and/or change out the front shocks for something off a newer model sport quad that you can get for cheap used because the stock ones are about as bad as it gets. Z400 shocks are great and cost me only 100$ but require making brackets.

 

This may not be what you want to hear, but if you are going to get a new bike in a few months, there is no need to spend any money on the Warrior. Keep the Warrior like it is just for a beat-around bike and put the money into the 660 or 400. You will have far greater results by modding the 660 or 400 than the Warrior. By the way, a Predator is also a waste of money. Every one I have ever seen is a piece of crap!
