Can anyone identify this part?

Howdy folks. Just got my head and cylinder back from Millennium, and in the bag of loose parts was this item. I can't identify it for the life of me, and I think it might not even be from my XS! If anyone can identify it I'd be much obliged, Thanks

It's the oil diverter that fits in the cam chain tunnel on the cylinder head.

It's on the intake side, right below where the crankcase breather and hoses attach. Keeps oil from spraying out the breather, I think.
