Engine cases
Dave487:
I've finally got around to stripping the engine and a few gremlins have popped up, mostly caused by physical abuse but no excessive wear so far considering the 61k mileage.
What I need to know is were the cylinders and crankcases originally paint or lacquered finish?
Mine has been very poorly silver painted, probably with a rattle can and the alloy underneath looks dark grey.
It's going to need a lot of preparation to get it looking right and I'm not sure whether to try nitric acid solution or have them professionally blast cleaned.
Any help on this would be appreciated.

Originally the crank cases were painted and lacquered.
Dave487:
Thanks for that Julie.
I think it'll have to be a professional clean. I tried the cylinder head in the dishwasher and I'd probably been better with a bar of soap and a toothbrush (b*** useless.

Just the top crankcase and the rocker cover had silver paint......(and the clutch cover, sprocket cover and alternator case of course)......... everything below the seam between the crankcases was plain alloy.
Never been too sure what if anything they put on the cylinders and head......it looks like nothing at all, but I'd be interested to know for certain.
