Break in?

[the Ferret]

Got back from a 120 trip today. Was taking it easy the whole way, but a short highway hop went really well. I've yet to hear the sounds you are describing, and I'm on tank 2 of 89 octane with 10% ethanol.

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.
