Okay first... I do use 91 octane fuel which is the highest octane I have around here. That said, Why do we need the higher octane fuel and if it is better then why do they even offer lower octane fuels at stations? And a friend asked if he could run e85 in his Harley I told him no but I am not sure. Also should I get something to boost octane if I have to fill up with a lower rating (a few stations around here only carry 89)
They offer 3 different octane ratings for people who are dyslexic. Some people look at a certain combination of numbers and see some other combination of numbers. To help minimize this, they put 3 series of number combinations to help minimize the chance that at least people with this disease will be able to see one of them.

I run 87E10 unless I am in over 4,000 ft. elevation (Sturgis) then I use 85. I run the 87 in a 750, 1 883, 3 1200's, 2 TC88's, 3 previous 96's, 1 96, 2 103's, 2 103 HO's, 2 110's. All run strong and with a combined 30,000 miles a year none have ever pinged from ocean to ocean and from Key West to the Arctic Circle.
I do run iridium plugs, SE wires, less restrictive breather and stock exhaust. I treat the bike at 3,000 miles with Techron to remove combustion chamber build up. I used to mist water but Techron does the job with less work.
HD motors are low compression and long stroke push rod motors. Unless you increase the compression and install a high over lap cam, higher octane is a waste and in fact will foul the engine more and CAUSE pinging.
With that said I do only run 93 in my 13 Street Bob with the 120R in it. Once I get 3,000 miles on it I will see if I can drop down to 91 and then 89.

One doesn't have to be a paying member of AMA to support their being. They're an essential Watch Dog group supporting motorcyclist, who all should be aware and supportive of. Just sign into their email and learn what the gov is pushing through that needs to be addressed with rebuttal for obvious reason.
The lobbyist that introduced w/o challenge, sustain and progressively voice increased Ethanol mixture into gasoline is just an unbelievable example.
