I was scouring the forum and the internet for information on painting or polishing the crankcase. From what I’ve found on this forum, seems like originally they were polished. Is this correct for the K0 and were they clear coated? Also, any suggestions on cleaning the head without getting it blasted? I’m thinking of using a plastic wire brush, and then polishing by hand and with dremel. Sorry if some of these topics were over discussed already and thanks!
