5300 feet above sea level is going to hurt your times bad.

Atmospheric pressure will not be on your side.

from the time i rode my bike in florida to the time i rode it here was only 4days apart, and it was a HUGE differnce.
in florida, if i went more then half throttle in first, it would rip the frount wheel off the ground in a hurry, but here, full throttle, or nothing wont get it up, i have to pop the clutch pretty good if i wanna wheelie.........kinda sucky, but 10x's the curvy roads, so its a good trade off for the bike.

The sea level is something many people do not take into account when they compare track times.

There are some pretty serious differences between sea level, 1000, 2000,...6000 feet.

Less pressure does not allow as much "decompression" into the cylinders when the valves open.
