What octane fuel you using?

So, yesterday, I rode 450 miles (along the Ilinois River Rd. from Chicago to south of Peoria. Nice ride, but I digress). I've been an "87 is fine" guy for this bike since I purchased it 5000 miles ago. On a whim, I started using 93 on this trip. I figure I had about half the trip with 93 and half with some blend of 87 and 93. There are far too many variables to list, so it is impossible to tell for sure that octane had anything to do with my impressions, but I did feel that acceleration, particularly when starting in 2nd gear, improved. I did not check fuel consumption. I am not suggesting that anyone buy higher octane to improve performance, but I am going to toy around with 93 and 89 octane for awhile and see if what I think I felt was something other than my imagination.
