Mark,
Did you get the Mono Seat Cowl (plastic) or the Urban Rack (aluminum)? I just installed one of the Mono Seat Cowls on my F3s, it seemed to fit fine and looked great. The first time I opened the lid to access the storage area, when I closed the lid, the plastic hinge broke? I'm going to run it back to the dealer on Tuesday. Hope this is just a one of a kind problem? I'm now thinking of getting the aluminum Urban Rack version if it looks like it's built better?
If the front of yours is loose, make sure that you have the two posts, that are the most forward part of the cowl, plugged all the way into the matching receptacles on the rear of the front seat. They sometimes don't seem to line up perfectly, so you have to move the rear seat or cowl around a bit, just to make sure you are plugged into both of them. Once you are sure you have both posts aligned, push all the way forward, that should tighten things up and make the rattling go away. And be very careful when you open and close that lid, with very little pressure mine snapped one of the hinges.
