I have aftermarket pipes on my bike which makes it pretty loud. Well the license plate rattles itself off. I have a piece of steel mounted to the license plate holder to put my plate on. I have had my last license plate actually crack from the vibration and exhaust air. That's why i mounted the steel plate which works to protect my plate. But I have tried screws, bolts with washers and nuts. It all just rattles loose and falls off. I thought of moving the license plate holder but I am not very mechanical and wouldn't know where to start. Any suggestions would be helpfull. Also looking for advice on where to find something to strap on or mount to my bike for extra storage, I have saddlebags already but they don't hold all that much. Just looking for something to hold tools and etc.
