John,Chris,
My gas mileage has been around 45 mpg,50 mpg if I ride it decent.
All I can get is corn gas in Utah, so yes it has been run with ethanol.

It's not a hesitation, it's down on power, like the timing's retarded.
Kirk recommends pulling the IAT connector in his videos on his earlier bike.
I pulled the connector yesterday and it runs much better, especially at stop lights, 52 mpg on the display. Rode for about 50 miles.
Everything seems normal including idle speed, acceleration
etc.
I would imagine the only thing is, that it would run a little richer and the timing is not retarded.
Ran good before, except when it was hot outside.
Thanks for the reply's...Randy
