So I was able to remove my 400's center stand pretty easily. I cleaned it up; now I'm ready to reinstall it...
Can anyone tell me how the mounting arrangement is intended to function? Is the inner "pivot" meant to be stationary, and the upper tube in the center stand should rotate around it?
If so... is this meant to be a pinch arrangement (see photo)? Should the bolts be tightened up enough to grip the pivot and keep it from rotating? When I removed it, the pivot wiggled out without my having to loosen those two "pinch" bolts...
EDIT: again with the rotated thumbnail!

Click on it, the full image should be upright...
