Ok so I have owned my 1981 kawasaki 550 for about a year now and have been told that you do not need to run anytype of lubracant in the crank case because the oil to gas mixture takes care of it.
Just recently I purchased a 1993 750 sx and the guy said that he runs mobil 1 oil in the crank case!!!????
I am now totally lost do I need oil in the crank case or not???
