Like ben says, totally different.
Have you done anything to it?
No powerband suggests the powervalve is doing its job right, its designed to smooth out the entire rev range spreading the power all the way up to peak power at 8500rpm.
That said, if you haven't done the "earth the green wire" trick it won't be opening at 7,000ish and robbing you of top-end power, so its well worth checking that.
Also, what expansion chamber have you got? A standard Yamaha part that is unmolested will also deny you of power. Not so easy to remedy, either cut it and gut it, or fit an unrestricted aftermarket one instead.
