No paint yet. I went to a paint specialist and they basically warned that nothing was going to stick properly as the hub wasn't primed/prepped. So I went over to my Yamaha dealer and showed him the flaking. He confirmed that the Italian-made bikes are painted straight onto the cast metal, and that flaking happens. He then called Yamaha Warranty who said that with me being a 2nd owner, despite the bike having less than 3000 miles, they wouldn't be prepared to address cosmetic issues as they don't know how the 1st owner treated the bike.

So ... I'm going back to the paint shop tomorrow to get some paint, will spray it straight onto the metal as Yamaha did, and we'll see what happens. I'll try to post a pic or two, and if the match is OK, I'll post a colour reference too.
