The part# for the threaded insert might be 16585-96..

I have one of the repair inserts in a bag in my tourpack with a couple extra screws. The insert has a screw driver slot on one end but I have been told that the screw driver slot goes in first. The inner fairing is really flimsy where the center insert goes and would be easy to break off and be big problems.
I didn't strip the threads on my center insert but the insert came loose on the OD when I had the 1 piece windshield bag on. Was able to pull insert out and epoxyied and did away with the bag.
I don't remember the removed insert being threaded. I also believe once you get the old insert out, you have to drill the hole oversize to accept the threaded insert. Again, the inner fairing boss is really flimsy. That's why I epoxied mine back in.
After writing this, I believe the above part# is for a smooth OD insert and the threaded "repair" insert is a different number. Hopefully, someone will chime in who knows.
These things are easy to strip, especially the 2 between the forks.
