I'll add one caveat to the altitude deal, and it's a small one. The idle changes the most in the extreme cases like I encounter in Colorado. You can address it by just reaching down and turning it up a tiny bit. The best way is to have a Kouba fuel mixture idle screw to replace that inaccessible OEM unit. When you get to Colorado and are maintaining a higher elevation on a more regular basis, you can turn the screw in a bit to lean the mixture at idle. With this and the idle adjust knob, you can take care of just about anything.
Also people not used to going to high altitude places like CO are under the impression that you're always at those extreme 10,000+ foot elevations. In reality you're only at the very highest places for very short durations. So if you try to jet for those extremes, you'll get lower than normal performance for most of your riding. So unless you're running overly rich settings at your home area, just about anyone should be fine for nearly anything they'll encounter.
The OP's 700-800 foot differential will be totally unnoticeable. Even in CO I don't really notice any serious effect until I'm cresting something like Imogene Pass outside of Telluride and Ouray at over 13,000'. That last 200 feet or so of climbing does cause some chugging but nothing that hinders the ride.
