I was doing a clutch plate replacement on a new to me 2006 Ducati Monster S2R800 Engine when I found this at the bottom of the right side engine case.
It is much larger than the 6 clutch springs, so I am guessing that it on the back side of the clutch housing where the gear is? I am guessing there are some springs back there that damp the engine load a bit. The real question is how f*ed am I....looks like I need to pull of the clutch housing.
Anyone have a spare ATPC clutch for a monster, I have a feeling I will need one....

Bad news for you, I'm afraid :-\
That is a part of one of the heavy springs behind/in the driven clutch gear (behind the basket), just like what you talk about.
If you're lucky it's 'just' a matter of replacing the basket & gear, but that spring part can do a lot of damage before it settles where you found it. The rest of that spring could be where it should be OR it might be anywhere else.
New or used APTC 620/695/S2R800 basket OR a complete 750 set OR a complete 696 set.

Good news, all of the large wire diameter springs are broken in multiple places. Looks like these springs fail from fatigue, and then the parts escape from the holder and cause massive amounts of damage. Fortunately for me the piece that I found must have just fallen out gently as there are no marks on the inside of the engine and I could easily put it back in place.
I could see how this could end in massive disaster if a large chunk of one of these stuck out into the engine case.
Also all of the small springs are still in working order, just the 3 large diameter springs broke.
