Which piece, where and how? Did you replace it with OEM bits or David's super threaded rod?
Actooly, I "snapped" some pics
The linkage is still intact. I went in there because it seemed to have an unusual amount of slack, and I wanted to see if there had been any hidden damage from the tourist taking me out last May (I fell over on the left side after the hit that snapped the forks). No detectable damage, so no replacements.
FWIW, I've carried a spare ball stud and threaded rod in my tool kit for years, just in case. Why? Because I'm not convinced that strengthening the shift linkage is the way to go.
While the BMW engineers have made some famous mistakes, usually there's a reason for their design choices. In this case, I wonder if the shift linkage isn't designed to give way before internal tranny damage is done to, for example, the relatively soft shift drum. With this in mind, I've decided I'd rather have the shift linkage break and have the likely-to-break pieces with me for roadside replacement, than to take a chance on being immobilized by tranny damage. Probably not very likely that I wouldn't have at least one usable gear, but why take a chance on even an unlikely scenario if I can avoid it altogether?
