Stripped engine sprocket nut
I was taking the chain off for maintenance and it got stuck. So I pulled the engine sprocket cover off and found the engine sprocket nut just laying in the cover. After cleaning it up I discover there are no thread left in the nut!

Several others questions come to mind in replacing the sprocket.
The front sprocket is definitely worn.

I read that you should change the chain and rear sprocket as a set.
If the chain is not stretched beyond the specification in the manual , is it really necessary to change the chain?
Do you change the sprockets on a schedule or on the basis of wear?1980 GS550L

The chain measurement procedure in the manuals is 100% complete unadulterated bull puckey.
Maybe it had some validity back in the roller chain days in the 1960s or something, but modern x-ring/o-ring chains simply don't wear out that way.
Back to the original topic, are the threads on the countershaft OK?1983 GS850G, Cosmos Blue.

I would rather trust my bike to a technician that reads the service manual than some backyardigan that THINKS HE KNOWS how to fix things.

I picked up a thread gauge at Lowes. The thread pitch is 1.5. I measured the inside diameter of the new nut and got 18.5 mm. I assume that means 18 mm nominal bolt size.
Also was wondering if the thread file or a die would be the better choice? Currently I have neither in my tools.1980 GS550L
