Metal chunk in oil

Not good. Most likely part of a trans gear.

Yes, it’s a gear cog. Probably third
Gotta whole 81 tranny on the floor across the I-5 bridge / Vancouver.. if you find more busted up in there.
PepperPete, Oregon where?

Yep. Tranny gear dog. Had a chunk off my 2nd gear on my 75 many years back. I could still ride her but it would clunk every turn. One night I did a tranny gear swap before a Week end club run. That and installed swing arm bushing swap out too. What an all nighter.

Plenty of descent oil still in it I see lol.
The rest of the engine is in fine shape. Tranny likely is too
Had a very similar piece of metal came out with the oil, 1979 SR500. It was a 3rd gear engagement dog. Bike was 15 months old - wrote a letter to Yamaha UK. The reply was a one-liner, The guarantee on your Yamaha motorcycle is strictly 12 months.
I guess yours is out of guarantee as well.

The good part is you found it early. One nice bit is you can access the transmission with the engine upside down so the head/pistons will not have to be stripped down. Still a fun all weekend job. You may want to replace the oil seal on the final drive sprocket at the same time. I find this to be the hardest seal to replace on an assembled engine.
The same thing happened to me:

Link to my broken transmission dog experience, with lots of good info, especially on splitting the cases, which is on page 3 of the thread.

Let's see the broken dogs next to each other:
DogBunny's and PepperPete's
Very similar break patterns.

Might still have the piece outta the SR - very similar again.
Wow, no kidding. The side by side is remarkable.
