Some test I did showed I did not get better mileage with high test but I also felt like the bike did respond better but after reviewing these posts I guess it was just my imagination.
It just seems funny that at 70 mph riding in a head wind 87 octane will give the same performance as 91 .
Just don't seem to remember it working that way back in my hot rod days.:lol:

I used that stuff also (burned out a few valves with it) and the price was not bad.

but I had a ready supply of 100 octane avgas (aviation gasoline) available -- for a price.

Of course when I started driving regular gas was a around twenty five cents a gallon. 8)
