Well, You can toss the "Shed" idea out. If it's big enough to house this bike it was probably built with the same venting as a garage, ridge vent and the soffiting(??) overhang which would be more than adequate. It honestly looks like he left it outside, and since It's not your bike, then you won't mind me saying that it was very poorly maintained. It does look like he either waxed it with steel wool, or sandblasted the chrome pieces! The bolts were taken off or put on with the wrong tools, it looks like a wrench slipped on the outside and seeing how it's an allen head, that's pretty funny. The heat shield on the same pic, well, it looks like it took the same wrench! What's the customer looking for, new parts, or bigger?
