Hey good luck led!
Those little warrior engines can be made into a fun screw-around quad with the 400cc kit and a good cam/pipe/intake. I have a warrior with a 400cc kit, .360 lift cam, FMF power bomb header, and FMF MegaMaxII silencer, K&N Intake, advanced timing w/ aftermarket CDI, MSD coil, and I put an Oil-cooler kit on it. (fixed up as a quad for my girlfriend at the time) and that little thing is pretty fun for a warrior. Does wheelies like a 400ex. Its a little heavy for jumping or whatnot, but makes a fun trail quad.
good luck again!
