Technical Help Needed lolol

[teamemmenracing]

I've worked on a lot of engines in my time, but this is the first time I have rebuilt my
Yamaha R1 2009 engine from the bottom up. All went well, until I found this wee conical
ring under the bench.

Does anybody have any idea what it is or where its supposed to go ? .......

Cant find anything in the manual .......
