The 87 (mine actually was manufactured in 86) is natural finish like you see, not the black that the later models have, although I think vapor blasting will remove paint too, but YMMV, and then you could repaint, but of course that's much more involved and expensive. There are some interesting project photos on his site, he specializes in Japanese bikes like CBX and CB-750, many of which clear-coated and plated aluminum castings, but there are some nice photos of an airhead he did. The only part that was painted on mine is the water pump cover. That one was half blasted by road gravel, so it was smooth under the paint, rough elsewhere.
For all the parts in the picture, plus the timing cover, cam chain cover, and water pump cover (not in the picture) and repair of the ding on the bottom end cover, it was $300 + shipping and he turned them around same day he got them (I was in a hurry). He'll quote you in advance if you send photos. It's by the hour. I originally was just going to do the top and bottom end covers, he quoted around $100.
