"The Wedge"

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?

I don't know when the wedge went away, but it must have been sometime in the early 80s, just guessing. Perhaps wirewrkr knows - he's familiar with stuff like that.

My 1975 /6 did not take a wedge. Perhaps it ended with the last of the /5 style controls on the 1974 models? Here's the wedge, NOT fitting:

My '74 /6's do indeed have the /5 controls and wedge.

I have a 1982 R100RT, and a 1965 R69S.

Never heard of "The Wedge", and don't remember seeing anything like that picture on either one. I've had both apart several times. (The R69S was apart when I acquired it)
Must have just been a /5 and /6 thing.

I had one wedge on my R60/2 (and the other was a homemade wedge, broken piece of plastic). The /2 controls are similar to a /5. Are the R69S controls different from a "regular" /2?

Locating The Wedge

I saw this picture before when I was trying to figure out "to wedge, or not to wedge" and I believe the photo is a little misleading.



The Wedge does not sit that far in, it sits out on the step closest to the camera. The Wedge is located directly under the pinch bolt, hence the cut-out on the back side of The Wedge.

This is the most inconsistant verdict ever.

to wedge, or not to wedge

I too went through the "to wedge, or not to wedge", question on my 1979 R100RT (PROJECT-S conversion) > http://advrider.com/forums/showpost....&postcount=248

I chose to wedge both sides, and then put a reminder note on the controls... as I'm old and forgetfull > http://advrider.com/forums/showpost....&postcount=259

My 1979 R45 had one. I found it in a box of "spares" after my build. Don't seem to need it.

[edit] Just noticed this is a necrobumped thread.

the question persists

it cracks me up to see this thread come back from the dead, but I guess as long as there are new airhead owners, the question still needs to be answered.

my airhead was totaled on labor day 2011, so I had long since forgotten I'd even asked...
