Bottom line, the engine never got hot enough to burn off fuel or moisture in the oil. Note that the measurements on the left engine cover really do not show the oil temp whereas the measurements on the right engine cover do. I'm not sure why the water pump housing was hotter than the left radiator or, the one time I measured it, the right radiator. That housing must be picking up heat from the exhaust pipe.

At Interstate speeds for about 15 minutes the gauge was showing two bars above the one for COLD, that changed to three bars as I slowed some.
My FZ-09 which I rode today maintains around 165 degrees(digital readout) rolling down the hi-way at 70 mph.
Fan cuts in at 205 degrees.
I am having a hard time believing that our engines are not getting hot enough once warmed up to burn fuel efficiently.
And it seems like a leap that it is related to unburned fuel in the crankcase.
Can't wrap my head around that one.
Then you would not see a correct burning color on my spark plug which I am seeing.
Let me know if I am missing something here.
