Does the clutch function? It looks like the end of the push rod #23.

I don't know if the clutch works, It's a salvage motor that I am rebuilding
and YES!! I just went and checked the clutch rod and it has a matching end to it! Interesting as to how it escaped? This could explain why the motor was salvaged. I haven't found much else wrong with it except the ring gap is at the limits.

The clutch push rod end part looks like this.
It's not this.

Its the shift shaft pivot pin, and it's not supposed to be removable.

Nope, Mine is still intact.
Here's a pix of my Clutch rod end
OK, I have found another weird thing. It appears this engine was running without Crank bearing pins in place. Every one of them is either missing or appears to be broken off in the holes. Somebody had to have been into this engine before me. Pistons are 1st over, so yeah.
Interestingly, the bearings seem fine.

Until I saw the first of the three pictures, I thought it looked like the top half of a valve guide.
could also be the detent rivet.... also not (normally) removable. Hint... use a ruler or somesuch when looking to id parts. Put it next to the item for scale.

Nope, That's intact too.
It's some sort of pin that is not supposed to removed. If you look carefully at the OP's original pics, you can see that it has been "pulled through" whatever it was pinning, and is damaged.
What's unusual, is the hole in it. The shift shaft pivot pin, for example does not have that hole.

Here's a pin with a hole in it to make peening easier. This one is for an XS650 front footpeg pivot. Obviously this one is too long, but your mystery part is pretty definitely a pivot pin. I just can't think of any other pivot pins on the clutch side.

the broken area seems to match the clutch rod itself. The clutch rod shows signs that it was hollow too.
I'm thinking that the spot or part it came from has been repaired or replaced, and you just found the broken part of it now. It certainly looks like one of the rivets from the shifter assembly. The only other rivets I'm aware of in that area are the ones on the back of the clutch basket, but I've never heard of one of them falling out. But anything is possible I guess, lol.
I love the detective work - besides from all the suggestions I have none - but man would I like to know if you ever figure it out!
Whatever it is the part has obviously been replaced and that is the original part, or a part from something else, that has probably been rattling around in there since the cover was last off. What's curious is it is obviously a riveted pin, obvious by the slight hole in the end and signs of previous peening. The length is a bit on the short side, looks too short for the back of the clutch basket and also too short for the selector shaft. Perhaps a part from something else that has somehow wound up in there by accident. Whatever it is, if everything else behind the cover is in place, then it's a part for the unknown parts bin.
Repaired and never got the old one out.Its been a long time
Doesn't know nothing.
Of course, it is always possible that it has absolutely nothing to do with that engine. We used to have endless fun putting a couple of extra parts in a box that had a stripped down engine or gearbox in it.
Cruel, but funny.

Found this while picking through parts today. Jim got it right. This is the backside of a shift drum stopper lever assembly. The rivet has the tell-tale peening hole, as seen in the OP's original pics. Everything else is right too, such as rivet depth. The shift shaft rivet does not have a peening hole.
The question now, is how the OP's failed rivet failed. It would take a lot of force to pull that rivet out. I think it would be hard to do if you tried. In use, it seems like the forces on that rivet would be sideways, not axial.
Properly done, I'd expect that rivet to last forever. I suspect it wasn't set just right at the factory.... just enough wiggle that it eventually worked it's way out.
That's the only scenario I can think of anyway.... it's pretty robust.
