preparing to do the clutch, as described in earlier thread, but today I cut apart the filter from an oil change I had last week and there are some tiny little bits of black stuff, looks like plastic. Some are tiny chunks the smaller then a pinhead and some are little tiny scrapings. Figure this has something to do with chain tensione pads, but thought they were brown.
other ideas?

I'll post a picture at some point, but with turkey day fast approaching and out of town plans, no promises.
