Ok, I have checked, literally, everything in the bottom end that is there. I still can find no evidence of any bearing coming apart. Also no signs of damage other than where the loose primary nut was rubbing the outer case cover and the Rekluse clutch cover seems to have been machined a little small and there is rubbing around the outside diameter. I see no signs of the transmission having chewed anything. I disassembled the transmission shafts, the PV governor, checked shift forks and drum, every component of the clutch, kick start assembly, water pump, and every support bearing in it. I just can't find anything to explain those chunks.
Only odd things I have found is the output shaft inner bearing isn't seated completely in the case and I have just a small amount of movement side to side with the outer water pump shaft in the bearing but that could be within spec. Unless there is a part that just isn't there any more, even though I have scoured the parts diagrams to check, I just don't know what it could be.
No way those pieces could have been floating around in there since new and just finally found their way to the drain plug, right?
