I just got a 2004 450 EXC a few weeks ago and I love it. I know a lot of guys are putting the JD Jetting kit in their bikes before they even ride them. I was lucky enough to meet someone during my first ride on the bike who had another solution. He helped me drop the clip 2 position (started at 3rd from top, ended at 5 from top). If you make no changes, you'll notice that your headpipe will start to turn blue. Dropping the clip didn't make a noticeable difference in the bike's performance, but the pipe stopped turning blue on me.

Hey Lew,

I tried sending you a PM, but your mailbox was full. I'd love to hook up with you guys sometime around Christmas. Just shoot me an e-mail or a PM and we can get together and admire each other's bikes!
