O.K., this might sound dumb, but oh well... I have built cars and work on them regularly, but this is my first bike... I just got my bike back from the 10k service and the clutch was slipping... I popped off the primary side cover and I can't even see any oil in there... Everything says is should be at the bottom of the "clutch basket" Someone else told me to the bottom of actual primary case (bottom edge of the circle opening) Does anyone have any help they can offer... It's a 2008 nightster... Does anyone have a pic of where the level should be?
