Starter Clutch Cover; HMMMMMM

Tonite I had some time to find that darn slow drip drip oil leak. It was coming from the starter clutch cover. I removed the three bolts, pulled it, and to my surprise!!!!Nothing. Removed the "o" ring. Looked good....., but, in the groove of the starter clutch cover was a small metal shaving....now where did that come from? I have never had the starter clutch cover off. Anyway, problem solved. Back to the track for Tuesday.
