Anyone else notice their Zeta handguards becoming discolored? I have the black anodized ones, and the black on the right guard is turning a slight brownish gold color. I think it's just getting sun baked. Where I park at work, the bike gets more sun on the right side during the day. It's not a big deal, but just looks different than the left side guard now. Might have to turn the bike and bake the other side to even them out.
