I assume the new bikes have the same ECU that is being replaced in the earlier models, ending in J12. Several of us have had similar issues with that ECU when taking off cold. Some characterize it as a "puff" through the airbox, or a brief loss of power. With mine it would happen making the sharp turn from my driveway onto the street. Another member found that if he let it warm up for 4 minutes it would never act up. I've never timed it, but around 3 minutes warm-up seems to work for me. Nonetheless, I try to keep the revs up in turns, maybe slipping the clutch a little until it's fully warmed up.
It's a little irritating that they can't get this right (the 650 seems perfect with regard to engine control), but I figure it is a reasonable trade for not having the engine stall at random times. My guess is there will eventually be another iteration of ECU for the 1000.
However, with the new ECU mine has never stalled, so your problem seems more severe. I would definitely take it back to the dealer as a warranty issue. There could be some setting or adjustment that's a little off.
