Lots of flushing out will be required at this point.

Shame on me, did some research, and yes, indeedy, the oil cooler has a coolent circuit on the FZ and it would appear that you have performed a Vulcan Mind Meld on your FZ, mixing the two fluids and forming a noxious mess in your crankcase . Much flushing of the oil sump and the coolent tank, radiator and galleries will be called for.......
