Narrative:

We took off out on runway 13L; kennedy one departure - canarsi climb; with gusty winds and behind a B747. We waited two minutes for separation and max power was used. After takeoff at 400 ft LNAV was selected and a left turn direct to canarsi VOR was flown. During the climb we experienced some turbulence and we overshot the canarsi VOR and the speed below 10;000 ft. We corrected our speed and returned to join the departure. No involvement or query by ATC; the flight continued uneventfully.
