"I took my new '12 F 800 GS in to the local dealership for some minor service—an installation of some accessory lights—(<1600 miles, pristine) and it was returned with the obvious "tool marks"/scratches on the fairing (see pics below). These were DEFINITELY not on the bike when I dropped the bike off for service. Any suggestions on gauging my response to the dealership? I know that my GS will get scratched up in the future, but I kind of wanted to be the one to do the damage"
Be aware that any repair short of ordering a new plastic will likely look as bad as the scratches. I don't know how you could prove the dealer did it even if you noticed it before taking the bike home. If the dealer values your relationship he will do something for you to ease the pain. GH
