Missing oil in '07 Superduke 990
Seeing a lot of foam in clutch cover, I did the water pump shaft and seal rebuild per the super helpful post on this forum,and filled coolant repeatedly after getting the bike together and filled the oil. (I was unable to raise front wheel 2 ft. to "burp" system as per manual, but did open bleed hole on water pump cover and on top of radiator.) Bike ran very hot on first major ride and after ride needed about 12+ ounces more of coolant. Also, after ride oil was not visible in sight tube at all! No sign of oil in coolant and I removed the outer clutch cover and saw no foam to indicate coolant in oil. Where did all the oil go? Any help will be greatly appreciated.
