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
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
