My 74 850 has a rubber grommet, or stop, on the lower yoke on the left side.
does it have a purpose? It isn’t near or touched by anything so it’s not a stop as such.
please satisfy my curiosity as it is there and intact.
Filling hole for steering damper mount ?
You'll have to post a picture. The only hole in the bottom yoke is for the brake hose.
Ok. Here’s another bottom yoke without the rubber fitted to it.
My Mk3 850 had the same hole in the bottom yoke and I used it to fit a steering damper - which is what I imagine it was originally designed for.
