I recently bought a 06 KDX200, and I want to make it a little quicker off the bottom. I've already read the KDX forum and the Hop-up tips, and I'm following them for the most part. But I had a question on the Pipe and airbox mods. I want to put an FMF Gnarley pipe on it and toss the airbox lid, but this will require me to rejet, right? I haven't been able to find what the recommended jetting would be, even on the FMF site. This is for Michigan riding in tight trails, 1000ft elevation, 55-90 degrees F.
