I've done some searching and I can't find it addressed.
Planning on a trip to the western US and there are some serious elevations out there, in excess of 7000 or 8000 feet. I remember driving areas like that in an old carbureted car I had at the time and wondering if I should anticipate problems in a carbureted motorbike or if I should just try to avoid higher elevations altogether.

CV carbs compensate somewhat for increases in elevation.
I recall I had to rejet a slide-carb motorcycle (CB160) to get thru the Rockies.

I've lived at 7400' for at least 24 years and around 300,000 miles (two Connies), you'll be fine. Good plugs, and a CLEAN air filter will go a long way toward good performance.
George is right too, CV carbs do adjust for altitude fairly well.

Thank you all for the info. What a great resource this is

I've ridden the Col de l'Iseran in France and that peaks at over 2700m (8800') above sea level.
My C10 never missed a beat, but you could feel the power dropping as you climbed. I reckon at the top she'd lost 20bhp, but the 80+bhp that remained were more than adequate. We didn't hang around at the top as the friend I was riding with is asthmatic and was struggling with his breathing.

You'll be fine, I took my former 86 concours up to 13k feet and it was fine. You'll lose a little power, ~20%, but its not unrideable, and theres no sense in rejetting or doing extensive work to prepare for it.
