I've had my '86 k100 for about 3 months now. Someone I met asked me if I lubricated the splines. Being that I didn't lubricate anything (& just didn't want to sound dumb :-[) I said no. I've come across a few posts about splines, but nothing with full detail. So here I ask while now feeling dumb, what the hell is a spline and how do i know to lubricate it? Is a spline just a bmw thing?
