    Try the 400EX carb and a 450R muffler. I saw a couple trikes at TF and they were pretty good.Get a good headpipe if there isnt one already on it. What octane gas do you run through it? I run 93 in mine and it does make a difference. You could play with the gearing a bit too. Stock is 13-39.

    Better exhaust. Better carb.

    I have a supertrapp exhaust and the 400ex carb on my X. It runs real strong, but it has alot of internal mods done to it.

    If you do a search I'm sure you'll find what year carb to get. I cant remember off hand, but I was thinking they were all the same. It takes a little effort to dial it in, but IMO it is well worth it.
