 So that's where those parts are supposed to go. Thanks much Ron for that last image and the useful clarification. I always tell people to ask you if they need accurate info about the P11.

I ended up cutting the threads off the part with the threads (that I bought new last year) and using it for a spacer somewhere else entirely. I couldn't make sense of how it worked or where it actually went not having a complete bike or any useful documentation for the P11.

I don't have that nut on the outside of the speedo housing that locks the speedo locking bush in place. Not sure it would have helped though. I still might not have been able to figure out where it went if I did have it. My speedo is locked in place with tension on spacers only. Very dangerous all things considered for how many miles I've put on that thing on the street.

Time for me to buy those parts and do something right for a change.

This is what my speedo side looks like.
