Going to ride the Colorado 500 next month! (I know. I got lucky.)
My 2007 WR450 is currently set up for sea level with all the free mods,
and the AIS removal kit. The kit came with a 48 Pilot jet (45 is stock), and
a new needle with the clip on the 4th slot down. It runs great.
What will I need to do to the jetting?
Does anyone know where I can find a Correction Chart for 7-8000 feet?
If not, could you provide the directions for this altitude from a JD kit?
I am hopeful I do not have to buy the kit just to replace a jet...
Any advice would be appreciated!

Thanks.
It appears I can get away with just swapping the pilot jet back to a #45.
