Ever had the carbs balanced?Unbalanced carbs will be most noticeable under 2500rpm or at low speeds, resulting in the need for more throttle and clutch control.Check the TPS is positioned correctly as well, if that's out that can cause low rev jerkiness.

My problem turned out to be worn plugs, the electrode on them was receding, they looked to be a couple of years old so I replaced them with NGK plugs and now the bike runs fine. The TPS was fine and the air filter was like new still.
I've just balanced my carbs and reset my TPS after the same symptoms as you've said you had sc0ttie. Mine sounded like a Subaru Impreza at low revs, very annoying! I changed the plugs, caps, and balanced the carbs. Made no difference. Mine turned out to be the TPS which was miles out! Took her for a short blast after doing all that, and the stuttering has now gone. Never had to adjust a TPS before in the 4 fazers and 100k+ miles I've done on them!!! Every days a school day!!
