Those look a little bit the aluminum washer that goes under the blind M6 (10mm head) nut on the bottom of the cases.
You only need one.
If they are larger they may be for the head studs.

Calling it a night since after I installed shift drum, kick starter parts, and gearshift spindle, I had 4 washers left over. I can't remember if those were already on the bottom of my cleaning can when I dropped the clutch parts in the cleaning bucket, or not.
