Another thing to be aware of is that your bike may run a little hotter. With the air being less dense, it's cooling properties are affected as well.

I was asking inquiring about the "You'll have about 20% compression loss here" comment. I guess i do not know if I am asking an altitude or a gas (oxygenated fuel) question. Was just wondering why the compression loss.

The higher the altitude, the less dense the air. The less dense the air, the lower the barometric pressure. The less pressure, the less compression. The less the compression, the less octane needed to ignite the fuel properly. Rule of thumb is a 3% power loss per 1,000' above sea level. The power loss is from lost compression. Just like your body can't get enough air when excercising at high elevation, your internal combustion engine suffers similarly. When in doubt TURBO or SUPERCHARGE! (autos & boats anyway)

Anybody running the Wednesday night races at Aztec tonight?

I went out to watch and Byron had pulled the plug. He's about fed-up with the wind... no races tonight
