I went to look at a Z400 for the third time. I looked it over more closely this time. The only grease fitting I could see was on the lower pivot point of the swingarm. There aren't any at the two top pivot points on the swingarm nor are there any fittings on the a-arms. I doubt Suzuki simply "forgot" them, so what am I missing here? Can holes be safely drilled and some sort of fittings be tapped somehow?
