OP In am in North Dakota too and I run mostly 91 because in a lot of stations its the only non ethanol grade available. The state of ND subsidizes the cost of ethanol here so most gas stations have it in the tanks.
Just stay away from ethanol blends and you will be fine.

My 103 with SE255 cams wants high octane. The best we can get in California is 91. At least thstbisxwhatvthe pump says. So, for those times my motor is not happy I carry octane additive.
During a recent Florida trip, I developed gas envy as 93 was readily available, and occasionally I saw ethanol free. The E0 was about $.50/gallon more than premium, and it was not indicated what octane it was.

The higher octane has nothing to do with "quality." As said before, it has everything to do with how much the fuel can be squeezed before it detonates. HD doesn't recommend higher octane fuel because of high compression ratios, it recommends higher octane fuel because of the heat our engines see. As heat goes up, the likelihood of detonation (or premature ejac... ummm ignition) also goes up. That being said, a modern bike has a knock sensor that monitors for detonation and adjusts the timing curve to minimize it. Don't sweat it so much.

I use what the owners manual says to. That said I use 87 in everything but this bike. Every once in awhile I put in 87 out of habit. It was no problem at all.

Twin Cams are designed to run on gasoline with an ethanol content of "up to" 10% (E10)... so E85 is a BIG NO NO!
