Hi Phil, cam covers, oil filter cover, tappet covers and generator cover are satin polished and clear coated. Top crankcase is silver lacquered.... I Don't want to get into debate but myself and Ben used Diplocor engine enamel DE1615 as the Simoniz stuff just didn't look right. My mate Graham Curtis used Halfords aluminium engine enamel which is a lot cheaper and more readily available. Lower crankcase is bare alloy. Barrels and head are bare alloy too. I need to check on top cam cover but clutch , generator housing and sprocket cover are silver enamel too. Hope this helps.
