My 250 has been doing it for at least the last 10,000mi+
I think what you're noticing is commonly called the "Kawai click"

From what I've been told it is indeed a weak automatic cam chain tensioner (CCT) that happens with a lot of Kawasaki bikes. Kawasaki supposedly just makes the tension a little low, thus the cam chain slaps around a little more, making some clatter. I have personally tried buying/installing a new OEM CCT, which changed nothing. I did that after checking the valve lash and they were all well within spec; just checked them again today and same deal.
I'm seriously considering a manual cam chain tensioner, but not to the 'do it' point just yet.
