My California 2003 stock jetted, no needle shimmed carb did OK from 5,000ft up to 9,500 ft with the mixture screw set ~1.75 revolutions out from seated. Since then I have enriched things a bit with mixture screw now at ~2.25 revolutions out but have not since been above ~8,000 ft. However bike still runs well with no "blubbering" or obvious malaise at 8,000 ft. California jetting is slightly leaner but you might get acceptable results with simply turning in your mixture screw a bit.
I would ride your bike as is in Salida and only tweak if it seems unacceptably weak. Colder Co. temps and any humidity might contribute to an effectively lower density altitude operating in your favor, or does that only work for aircraft?
