I guess I should be thankful for my fork debacle. If it weren't for that I would have run off on a long trip and this could have happened several states away.
Fixed the forks last weekend and went to go riding with fellow FJR rider Anthoney today. He noticed the bag was wobbling and then I hit a bump and it started flapping up and down badly. He rode up and signaled for me to pull over pointing to the back of my bike. I figured a bag had come open or something but when I stopped and looked I knew immediately what it was.
We didn't have the tools to transfer the bag over to his bike, so I rang up the wife who was 20 minutes away and she came and got my bags and we rode the rest of the way home.
So, now to figure out THIS fix. Looks like I'll be fixing the subframe, fairings, and buying a GIVI rack and a Gerauld stiffy kit. Sigh...
