Hi all. It rattles and clunks over simple neighborhood bumps even with nothing in it. Flexes if you move it with your hand. I assume its flex is due to the cheap givi mounting board rather than their more robust ones. I assume they all came with the generic board I have on mine. Any successful options to fix, adjust, reinforce without buying a better mounting board?
BTW - in all other regards it works fine, sits straight, etc...
