I'm with Darrsi on this,
For a month or so I ran alternate tanks of shell v-power and normal shell every 2 days (my commute uses a full tank every 2 days), you can definitely feel a difference and doing it over a long period like that negates any "placebo effect". When switching it does take a few miles to kick in, presumably the old fuel is still in the fuel lines/carbs but when it does it runs crisper and has slightly more zip.
As far as I know my bike is stock (apart from the silencer that is), I checked the needles not long after I got it to see if it had been "ivanised" but they are stock although I didn't check the jets (maybe it has a different kit in it I don't know), std air filter etc. It did have race supersport tyres on though (Pirelli SC1 K2's), either they were bought second hand or the bike had been on a track because they were bobbled off the edges on both front and rear so it could be that the previous owner fettled it for track days, who knows.
It is odd that people find their bikes run poorer with it though, I have always tried v-power in my bikes and never had any detrimental performance. In fact, my lawn mower even runs better if I syphon v-power from my bike when it needs filling, it sputters less and doesn't have a slight stutter when going from tick over to full throttle and that surely isn't setup for high octane fuel
