Fuel availability seems to vary area by area. I have nine motorcycles (all with carbs) and stay away from the ethanol. It turns some carb floats heavy over time and turns many of the rubber parts hard. The only fuel we can get in our area (Minnesota) without ethanol is 91 octane. It works great in my 986S and my high performance bikes. I have four older BMW motorcycles that don't require the high octane and I still have to buy the high dollar premium fuel to get it ethanol free. If I cross the border into Iowa I can get 87 octane ethanol free at a much cheaper price. I wish we had it available here in Minnesota and Wisconsin.
My bikes are a pretty wide variety. Dirt bike to full dress road. I do rotate the street bikes for commuting. It's a bit of a pain to keep them all fresh gassed and running good.
Bikes tend to run better the more they get used. Same with the 986S. My winter car is a Subaru that doesn't seem to mind sitting near as much as everything else I own. lol
