I'm having a bit of a time with the right-hand panel on my 650 (AL2). Earlier this year, we fitted heated-grips and a USB socket - running the wires under the tank and tucking them up in place with a few cable-ties. Removing the large white panel made life much easier.
However... getting the thing to "seat" correctly has been a right faff. It's just not quite "in", and occasionally pops out showing one of the clip moldings. I've had the whole thing off, the little velcro pads are in place and the panel just doesn't seem quite in place. I've read elsewhere that the trick to learning how this plastic parts go together is when you break them trying to get them off! Is there a knack to this as I've had the thing off 3 times. Sitting on the bike, it's quite noticable and there's few mm difference which my attached picture may show.
