| Actually it is not uncommon to find stuff like that around the gauze filter on bikes that have been 'ordinary' dealer serviced.
Although it is not good news to see it, without knowing the service history, you have no idea how old the debris is, and it could have been there since the time the engine was first built.
The crankcases have very good baffling, so anything heavy is likely to stay put very 'nicely'.
Having said all that, I scrupulously clean my cases out as far as I can get with with magnets on wire and bent pipecleaners cos I like to know when anything new arrives.
The rubbery stuff is gasket-goo btw and to be expected.
The orangy-brown [plastic but sounds like a bit of the gauze-screen holder, so check that it is intact if you are reusing it. (they can be damaged by heavy-handed fitting by 'untrained' mechs) |
