04 stock jetting & 10% leaner (going to Colorado)

[JLC]

I'm helping my buddy get ready to go out west and we need to go 10% leaner on the pilot and main. So my question is what is stock for the '04?

Thanks in advance,

Jay

For a completely stock bike: stock is 42 pilot, clip in 4th position, and 165 main. Depends on where you are and temperature but I live at 5,000 feet and run a 42 pilot, clip in 3rd position (in summer) and 162 main. If you're over 8,000 feet I would go to a 160 main and depending on temperature maybe go to a 40 pilot. If you don't already have a fuel screw get one cause you will be needing to change it if you're climbing/descending a lot. Have fun this is a great time of year to ride here.

The bike is mostly riden between 600 and 2500 ft now and seems fine. Thanks for the info ?
