Correcting myself...did some thinking. Higher altitudes = less dense air = less oxygen for fire. This means that you actually have to lean a carb out at higher altitudes (usually smaller main jet...and you're right, only at pretty high altitudes).

What I did on my bike made it run richer...so basically, for whatever reason, it seems manufacturers just set it too lean out of the box.

I'm going to continue to run on the rich side...especially for break-in. Runs slightly cooler plus it will probably be the correct setting for the fall when the weather gets colder around here.

Cheers,
