The problem is easily fixed, use better locks! They're made out of that white metal alloy that tends to break way too easily. Most cheap chinese bikes I've seen have the same thing happen when locks are made with this.
For a pannier or tool box ok skimp on using cheap bits but the airbox I'd have spent the extra pennies to have a box that stays closed.
I'm guessing the lacquer was put on with dirt or fingerprints on the bike prior.. I know I have someones fingerprints under the lacquer in a few spots inc my tank, which would explain it lifting so easily.
I've been riding an XJ900 chop the past week but took my bandaged C5 out last night, she's very fun to ride, but I think I may just leave her at the dealers for awhile, the bike is going into false neutral more and more and Im having to double clutch alot.
