That's a well-done blend of the K6 and K7! You have the better parts of both bikes as far as maintenance is concerned (and easier tuning if needed).
I like at 6000 feet, In Colorado. I can say this for the area where you live: the gasolines have been adjusted in their burn rates for the altitude where you live, within 2500 feet or so. This usually means you won't have to be concerned with 'tuning for altitude' unless you're looking for every last HP. Largely, you won't need to do anything. If the sparkplugs tend to get dark and foul, use less octane: originally the K7 Owner's Manual told you to use Premium grade, but today's fuels burn much too slowly for that to work now. So, for dark plugs, go toward Regular grade instead. Also add a couple of ounces of oil (any oil will do) to the gas tank at fillups, because our gas is now very 'dry' compared to the 1970s, so it ends to wear the top-end parts like valves guides and piston rings faster than normal.
For example: for around-town and freeway use, I run Regular grade. If I'm heading out onto the interstate for 100+ mile ride, I'll use Midgrade. If I head downhill toward Missouri or places South (TX, etc.) at low altitudes, I'll use Premium every-other tank, Midgrade the other. This keeps the sparkplugs cleaner longer and cools the engine and pipes better by burning the fuel more.
