Any idea where this part comes from?

[RBoss]

Hi all,

I am in the middle of taking my bottom end apart to replace my primary chain + rubbers. Going smooth (so far), making notes and labeling parts, but (i think) after flipping the bottom end over to loosen the bottom case bolts I found something lying on my workbench. I couldn't find where the fiddly part comes from and the manual didn't mention it.

Is it some kind of oil jet?

The situation:

The part:

Anyone who recognises it?

Cheers,
Ruben

Goes between crankcase and barrells, should be two, one ate each side and only fit one way up. Make sure they are clean.

NO silicone gasket goo anywhere

Thanks! After pulling the primary shaft out the other one fell out as well  . All clear, thanks for the help!
