Yes, I do sometimes remember given that I drive with window down as often as possible. But I must say, regular maintenance has kept the sunroof working flawlessly. Clean n lube every 6 months. I have to get the bike back on the road, then I'll work on the X. It's cooler now in FL so not so bad to work outside. I'll check the clips, I did spray dry lock lube on the reg rails and then did slide up n down much better. It's a process.
