Next time, I'm headed up north to get me some gasoline from the station that sells ethanol free. See how that goes.
Edited for failure to proofread.
19% ethanol? Holy crap I thought the limit was 10% and they were talking about upping it to 15%
Like I said, while riding I cant hear it unless I'm leaned over to left or right,accelerating as it pulls me thru a turn. I imagined it was either "pinging" aka ignition knock, or hearing the cam lobes coming around and smacking the top of the shim. I on't think its any kind of issue with the bikes, just a characteristic.

The limit is 10%, the concern about the 15% is that it will wreck smaller engines that aren't designed to deal with it. The AMA has been pushing for, among other things, separate pumps so that there's not any leftover 15% in the line when you go to put gas in your motorcycle.
