That part is the oil screen cover. If you have never taken it off, then you have never cleaned the oil screen. The most important time to clean the screen is at the first oil change, but it is not necessary to clean it every oil change.
Just go to the Kawasaki dealer and order an oil screen cover, gasket, new drain plug and lots of plug gaskets. You will be back on the road in a week or so.
Castings can have flaws
