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?
i have heard people suggest that but since zuki didn't do it, you probably don't have to. they are greased and sealed from the factory, so unless it starts squeaking, leave it alone.
There are a total of 3 on the lower suspension for the rear. Front A arms are roller bearings with a steel rod for the inner bearing sufrace. Drilling into this would ruin it for sure. I took mine all apart and packed them with grease. If you do this be aware the neddle bearings will come out and it will take some time to get all those littlr buggers back in place. Well worth it though if you want to avoid giving Suzuki any more money.
