High altitude jetting help

[Jtl13]

I'm going to Colorado for a 4 day ride next month. I have a 13 200 xc. My area(western KY) is around 400' elevation. Going to Silverton CO which I believe is 9000'. I currently have a 38 pj, 70 main, and n3ch needle in middle clip. Jetting is close but I know needs to be changed for the elevation and temps. 

Suggestions?
