I would think that any wobble noticed at this point would most likely not be fork assembly flex which seems to be built rock steady.
Per previous post's discussions check,
Tire Wear / Condition
And possibly fork assembly "fall away" in reference to headset bearing tightness ect.
The F and mine included appear to be a pretty solid high speed bike for a cruiser so with all the above items in spec there shouldn't be too many issues with a good triple digit rip every now and then.
