I have a little over 50,000 miles on my bike. I almost always use 87 octane fuel and only paid attention to the octane and ethanol content when I was a newer rider -- spent too much time researching back then. Thing is, that I ride all year around and my understanding is that ethanol does whatever harm it might do if fuel is sitting in the tank for extended periods. I dump a bit of Seafoam into the tank every couple of months (if I remember), but that's all I do. This has worked for me, but if you're not riding 5-10,000/year, maybe some of the other tips will get you better results.
