XR 250 Jetting at Altitude

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.

I'd tell you if I knew. :thumbsup: You may get a better response by moving this thread to the "Jetting" forum.

I rode one of my XR280s around the Taylor Park area one year, 125 main and 42 pilot worked pretty good.

Creeky...thanks for your reply and help.
