04 400ex Pipe ?
#1
Would all years of pipes fit the 04 400ex. I know the changed alot on it and was wonderin if that was one of them. I just bought a HMF slip on and it never said what year it is for. Any help would be great. Thanks

With a HMF, you will need to rejet the carb. If not, you could possibly damage the motor by running to lean of a mixture and besides, you won't get hardly any performance gain if you don't.
I had an 04 400EX and loved the quad. I had a Pro Circuit slip on and it done really well. If I had to do it again though I would go with HMF. Thats what I'm running on my Raptor............... [img]i/expressions/face-icon-small-smile.gif[/img]
