I have a 2002 Honda 400ex and it is a great quad. It always starts and it is very powerful. I mainly trail ride with my buddies one of which has a 2003 Banshee and one who has a 2001 Warrior and the other with a 2004 YFZ450... Yeah they make fun of me for having a Honda, but when we get out on the drag strip, my 400ex will easily outrun the Warrior. The Banshee gives a pretty good run but I usually win by about 1 quadlength. I was however impressed with the 450 race. With my simple upgrades I can hang with it, but he always wins by less than 1/2 quadlength. If I could change one thing about this quad, I would make it just a bit wider. It sits too high for fast turns and I put smaller tires on it to compensate, but then my 400ex didn't have the ground clearance for the trails. But just like all you guys with a 400ex, you CAN ride a wheelie for ever on these mothers!
Upgrades/Accessories: Stage 2 hotcam, 426 big bore, A/C nerf bars, renthal handlebars, and racing carb(keihin). The most important things I got for this quad are the +2 rear axle and +2 A-arms. With these I was able to put on the bigger tires and still was able to fly around turns without breaking...
