I was working on my gl1800 today. Had to take the seat off. When I took it off the right side panel just fell off. Turns out the four rubber grommets that hold the panel were gone and it was being held in by the bottom edge of the saddle. Fortunately I had a set in my toolbox. I have heard of loosing one but not all four. I am glad I wasn't riding on the highway and had the panel blow off.
