IBLEEDORANGE   Posted July 9, 2005 I am putting a power now in my 05 250x on the intake side. Will I have to redo my jetting? It would be helpful if some of you guys can give me an idea of what you had to do. ex..go leaner one, two, richer, etc... Thanks, JIM MAN IT'S HOT! DO THEY SELL LIQUID COOLED HELMETS! 🙂 Share this post Link to post Share on other sites
mxcrider   Posted July 9, 2005 I put it on both sides of my 450 and all I had to do was make it a little leaner. I will have to say it is the best mod I have ever done on a bike. The power is so much smoother now and it feels like it never lets off. Its a better mod than any exhaust I have ever put on. Share this post Link to post Share on other sites
Hawaii-Rider   My Rides (3) Posted July 10, 2005 I have one on my X, was running the JD jetting kit when I added it, and didnt change a thing jetting wise when I did. The X responds very very nicely down low to the blade, as does the 270 kit from Thumper Racing. 🙂 HR 🙂 Share this post Link to post Share on other sites
