    I spent a good chunk of my day cleaning this area on my bike in preparation to change the chain and sprockets. I just described the crud living there as

    "That dark matter under the clutch cover of a motorcycle - an amalgam of chain lube, engine oil, road tar, bits of gravel, worn sprocket dust, and possibly hair and emulsified despair, with the specific gravity of Marvin the Paranoid Android's thoughts" not 5 minutes before looking in on this thread.

    Anyway, I used Purple Power, then Foamy Engine Brite, then some brake parts cleaner. Passable results. I should try the Steam Shark on it. Uggh.

    Cleaning me off was almost as challenging as cleaning the bike.

    A friend that owned a pool repair company gave me a couple of nice 5 gallon buckets (for pool chemicals) with a lid. I used it to drop in a head or cylinder, along with a gallon of berryman's carb dip, in the bucket in order to clean the parts. Shake the bucket every so often to distribute the sauce over the part and let it soak for a few days and when you pull out the head/cylinder, it's clean as a whistle.

    I use purple power concentrate from orilleys. 50/50 mix in a spray bottle. And orilleys has a three pack of brushes with metal bristle. they look like big toothbrushes to me. Some 00 grade steel wool and green scotch brites will help too. I cut scotch brites into squares and use my hemostats to get into tight spots. Tightly stuff rags into intake and exhaust ports before rinsing WELL with garden hose. Last step before painting is spray it all down with acetone from a spray bottle and dry with an air hose. I then paint with VHT UNIVERSAL ALUMINUM. Part number SP127.

    Haha, you guys are great. Gormin's gourmet GS, it rolls right off the tongue. Ed, thanks for the Berryman's tip, though the engine's already been reassembled with oil+filter changed.

    Chuck, that engine looks sweeet. I'm going to VHT gloss black on mine, though you think I can get away with use of isopropyl alcohol instead of acetone?

    Alcohol will do. I acetone everything real good just before paint to ensure its absolutely oil and grease free.

    Now I just gotta find that paint.

    Yes,chuck's engine is so nice it's frightening. I'm not allowed to have anything like that because I will ruin it in short order.
