This is driving me crazy.

The bike has 11k miles, brand new battery (i tested voltages to confirm...it's not the battery trust me), newly adjusted throttle bodies, new plugs last year. fresh oil change.

Sometimes the bike start like crap...sometimes it starts like this. Any thoughts?

I would guess a fuel problem. Either the fuel pump or injectors.

11K is not alot of miles for a 07'. Possible degradation of fuel lines from sitting around too long has released contaminant. Which could clog injectors.

Change the spark plugs yet? Service life of only 8,000 miles

No idea, but that doesn't sound good!

"newly adjusted throttle bodies".. as in, the problem sprung up after you messed with the screws ?
If it's been sitting a long time (noticed your in Chi-town) i would 2nd the bad gas suggestion. Doubt it's a fuel pump, as it won't run well at all, and won't rev if it's even a few PSI below spec (47psi).

pinched fuel line from lifting the tank?

I think maybe it's the fuel pump. When you turn the key to "on", then turn the kill switch to "on", do you hear the pump priming?

If yes, does it sound weak? (maybe post a video clip of the fuel pump priming and someone can compare to their bike).

When was the last time it ran fine? What have you changed/adjusted/modded since then?
I know you mentioned plugs, throttle bodies and oil. Did it ever run fine before/after these changes?
