Riding the C10 in higher elevations

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.

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.
