pulled out the valve head , the throttle bodies .. found this on the floor under the bike.
does anybody know what is it and where it fell from? is it from the bike? its made of some hard plastic, feels like its heat resistant, looks like an opener valve shim.. but i know its not

No idea BUT you can go to the Ducati site and download the exploded parts diagrams for your bike.  Look through the head section for likely candidates.

It's the small plastic bung hole cover that hides the air bleed screws on the throttle body. It is there to keep us lesser humanoids from adjusting ourselves into oblivion by turning said shiney brass screws.
