I'm still a noob in the world of airheads, and I only very recently became aware of the wedge that is part of the handlebar controls. I installed a handlebar mounted master cylinder from the 88-93 RS model, and I had no recollection of having installed a wedge. This concerned me, because I read that without the wedge, you stand a good chance of cracking the perch when you tighten it down. I ordered one, then went to install it today. There doesnt seem to be room for it. I looked at the parts fiche in Max BMW, and it does not show this M/C perch as having a wedge, but curiously, the clutch does. What am I missing?
