IMHO, surging below 2k rpm is irrelevant, as there is no reason to ride
lug the bike at that low an rpm.  Sure, the ST has lots of torque, but
come on, downshift sometimes.  :)

You might also try running a bottle of good quality fuel injector
cleaner like Chevron Techron through it, although your bike sounds
pretty new, so maybe this isn't necessary.  

But, yes, the Sprint has a great FI system on it.  If you're really
worried about it, you could always ask your dealer to check it out.

Laters,
