i just got a 1999 400Ex and for a great price. it has nerf bars, a twist throttle, full skids, and a white bros exhaust (slip on i think) all for $1500.
there are a few things that i am wondering and i hope you honda guys could help me out. would a 400EX beat a warrior? what is the deal with 2 exhaust ports? is there any feedback on this machine (ex. what went wrong, mods, how you like it etc.)

thank you and sorry for the long post

 

Yes it can beat a warrior and do a search for 400ex in different parts of the forum and old tpoics should come up that will answer your questions.
