I'd say around 500 before you can really let go. I would think the honing marks will still be there from new at 1250 miles. Best do an oil change after 250 or so.
I would advise against a "hard break in over the weekend" It doesn't work that way. With rings it is more about initially keeping piston speed down than throttle loading.
The spinning rods is a serious sounding weakness. A recall would be very expensive for Kawasaki since there are so many ninjettes. If they can pin the problem down to a narrow window of engine production numbers then they might do it, if it is a general problem don't hold your breath.
What were the symptoms? so that other owners can minimise damage if it happens to them.
