What the heck is this thing? (TWSS)
I pulled out the air cleaner to blow it and vacuum it out, and this little oval rubber grommet was just sitting in there, literally just resting on the paper filter on the inside of the air cleaner. I picked it up but could not locate any area in the air cleaner intake housing, or in the cavity inside the bike, that seemed to be missing a grommet.
This is from my '07 919. Pics attached. Any ideas?
