Bear with me here. I don't remember the exact octane ratings but my local station has started carrying regular (I believe 87) non-ethanol gas....which is obviously better to run (especially since my firebolt sits for a month or two at a time)....anyway I usually strictly run super, but would really prefer the ethanol free gas. Is 87 good to go? Would an octane booster help or is that all hype? Any suggestions? Thanks all

I've found this to vary by bike, some of my XBs run fine on regular, some will ping. Try it and see. If you are not beating on it, 87 should be fine.
There have been plenty of times were I've been forced to get 87 due to availability, and it has never presented an issue.
Don't bother with octane boost. If you really want to use some, make sure you get some that is O2 sensor safe, the cheaper ones will wreck your sensors.

Your results may vary...but I'd stick with the best available.
The way mine's tuned, I NEED to run the high octane stuff, but even stock, to me...it's not worth the few extra penny's for the low octane stuff, especially during the summer.
Winter (colder months), yea, you could probably get away with the lower grade gas as long as you have a stock tune-up in your ECM.

The alcohol acts as an octane booster.
Tuners have found that they can go mental with compression ratios and boost when using E85.
That having been said, the alcohol has less energy than gasoline and you will notice a drop in fuel economy.
If you're going to be storing it for long periods of time, I would opt for the 87 non-corn flavor.
If you don't lean on it to make it ping, the bike will probably do just fine with it.

What 93 gasoline storage time is?

Typical 10% ethanol gasoline starts to degrade in a month. It doesn't become 'un-useable' for quite some time, depending on if the storage container is sealed or open to ambient air. The biggest issue, is how quickly ethanol degrades seals, injectors and fuel pump sending units. For this reason alone, I won't use it in any of my bikes. In both of my Aprilia bikes with fiberglass/plastic tanks, it causes the tanks to actually swell so much the paint on the tank can crack, and fitment of the bolts becomes extremely difficult. In upstate NY, we have a local convenience store chain (Stewart's) that carries 91 octane non-ethanol fuel. Look around...they are out there. Any vehicle manufactured before 1994 will REALLY struggle with today's ethanol fuels, regardless of brand or additive package.

I use Pure Gas app to find non-ethanol. Some counties in NY, like Dutchess, do not allow the sale of non-ethanol. I use it in bikes and vintage cars

Yea todays gas really deteriorates quickly in SoCal in the summer.
I've found that just using plain ol "StaBil" works very well.
You can buy the normal stuff, or get the version FOR ethanol. I've seen no difference in performance between the two.
Now that I've retired, I'm not on any of my bikes NEARLY as often (every day!) as I used to be. So...I keep at least some StaBil in the tank so the gas doesn't go totally to hell.
So far, no problem in either my XB12s or my RX.
