As per Gryph, however you need to keep the rear tank pin "C" clips fitted if you wish to keep your covers. The covers are held in place by the spring clip and the rear edge of the tank. If the "C" clips are omitted what can happen is on hitting a bump, the rear of the tank jumps, the side cover disengages with the tank and the cover goes AWOL. There are a lot of variables, tightness of the rubbers, size of bump, fuel load and speed. But you've got to ask yourself "Do you feel lucky, well do you"?
