I'm looking at buying an early SOHC, probably '71-'74, and have been browsing Craigslist. I notice some bikes' crankcases are mottled, or splotchy, the effect of weathering, I suppose. My question is, to what extent is this fixable? Were the crankcases painted? Is this splotching in a clear coat? Is the only solution to repaint (assuming they're painted in the first place) or can they just be cleaned/polished? Thanks for the input. I want the engine to look good, but I don't want to start a frame-up restoration at this point.
