Pictures say a 1000 words, so to speak. And welcome to the forum.

That looks like the pin for the oil filter. If you have the oil filter and shaft handy, see if the pin fits into the shaft and then slide the oil filter onto the shaft. On the backside of the filter, there is a notch milled out where the head of the pin fits into. Hopefully that's it, if not, perhaps somebody else will jump in with an idea.

Dimensions don't fit the oil filter pin which is much smaller.
I wonder of this part belongs to the CB72/77, I don't recall such a part.

Don't know that I've ever seen that part in a CB/CB72/77 engine. ............lm
