GearNut- I believe I've mentioned to you that my bike is up and running!
To update here, at 5,500' I had to turn the air/fuel mixture screw out 3 full turns. There was a lag in the engine between say 3mph and 10mph, it was being starved. That problem has nearly gone away. I intend to experiement a little more to dial it in, but so far I could'nt ask for more. It is possible that re-jetting the carb would be an overall improvement...
