Recommend fuel octane?

This might be stupid but I see no recommended minimum octane rating for this bike. Another forum someone mentions the owners manual says 91 RON which is essentially 87 R+M/2. I had 1974 Honda and kept ethanol free gas in it and my other bike 2006 Honda 599 has carbs and I keep ethanol free in it. I have a convenient source of 91 octane ethanol free and likely will just use that anyone know of any issues or where RE specifically states a recommendation

I hope there is more input on this thread. I run a Classic 350, thats just a single cylinder thumper and I have been using premium fuel.
Sunoco, mostly because that's what I sold when I was in the business
Old bike with a carb I would run ethanol free highest octane I could find. Fuel injected bikes I'm not sure, might be a waste of money

Im pretty good at wasting money :rolleyes:
Ethanol free isnt easy to find by me but Im thinking of using it for the last couple of tank fulls before I store it for the winter. No riding for me in the northeast in Dec, Jan and Feb
my auto mechanic convinced me to never run ethanol gas in carbureted bike. before that discussion I ran ethanol free probably 90% of the time. After 6 months of never running any ethanol my floats never stuck again,
The ethanol story is a sore subject .. In a dry , warm environment , there is NO problem High humidity cooler temps , that is where the most problems show up ....,Especially if the bike sits for an extended lengh of time ...,This is after many years of observation ... ,I'm in Deep South Texas , Michigan born .. , Never a problem with an average of 12 bikes on hand at all times . I use regular pump 87 octane . Year round ...., Never a problem ....,
unfortunately my bikes sit and eastern NC is hot and humid that was likely part of my problem with 10% ethanol gas

Yes , the ethanol does attract moisture . You are better off with non ethanol fuel ...And the 87 octane should be ok to run .. All I use in mine ....
Ethanal should be banned plan and simple for what it does....

It's NOT the fuel .. If used properly , as intended , it works fine ..... Fuel was made to burn , NOT sit in a fuel tank , or gas can in an old building ......

The Interceptor was made to eat the cheap stuff. It has to survive the mean streets of India. Anything more is just waste of money.
