Hi Guys, I'm new to the board after just purchasing a 1998 XR250. I did a search to try to find my answer on jetting for higher altitudes, but didn't find (or missed) what I was looking for. I am wondering what the ideal jetting is for my 98 XR 250 with the Gordon Mods, Hot Cam, and Uni-Filter would be? All of my riding will be done at 6-9k feet. Any other suggestions are welcome and I appreciate the help.
