Motobecane engine sludge

This single post is part of a larger thread. Start from the top or view this post in context.

I recently purchased a 50v and out of curiosity I opened up the engine to check the shape of the rings and piston. Turn out there is a bunch of oily sludge sitting down in the crank. I'm afraid that some of the sludge will break loose and scar the piston or cylinder walls. Any suggestions with this? Clean it out? With what? Etc.
