Have read several posts regarding CVO owners discovering the granite powder coat coming off their engines. Always felt sorry for these guys until about a month ago I found the same thing on my engine. Someone on this site posted the HD recommended repair for this problem (yes I know it sucks that you spends $30k on a bike and the engine coating peels off). Nonetheless, I spent $23 on a can of HD granite spray paint and made the repair. It wasn't as bad as I thought it would be and the results were better than I thought. If you're contemplating this repair, here's what I did:
1. Sand the area and be sure to feather the edges of where the powder coat is missing. Even though it may feel smooth, you'll see the "ridge" if you don't sand the edges well. Following this, clean the area with a solvent...I used alcohol.
2. Mask off and cover your bike.
3. Make a cone from a piece of paper, which will allow you to paint a narrow area.
4. Make short bursts of paint from the spray can (I pushed the button on and off as quickly as possible).
5. Use a hair dryer or heat gun to dry the paint.
6. I put a total of three coats on the area.
It will take you longer to mask off and cover your bike than it will to make the repair. I probably went overboard on covering the bike-the painting wasn't as messy as I thought it would be. Photos show: bike covered, before, after, and the cone I made, along with the can of $23 spray paint. Sorry, couldn't get all pics in one post.
