I have a question about the Mototrike manual you posted here. I am presently proforming all the maintanence checks on a 99 RSV motortrike and am a little confussed which doesn't take much. It states in the manual,the ford rear end should be filled to within 1/4 to 9/16 inch of the fill hole. About 3.3 pints of lube. I've pumped 2 qts in and am still not near the fill hole. Is it 3.3 pints or 3.3 quarts?
