Hey guys i just recently purchased a 1972 Sportster 1000XLH.It is right hand shift and is all original.I´m the third owner.It has 8,300 original miles and looks brand new(Garage Kept).I was wondering how much gear oil it´s supposed to hold,and how to measure it,and do i fill it on the left side of the engine through the screw out cap.Thanx for any info.Jason
