In the last 7 months my bike has "lost" 3 rego stickers. They are in a metal holder, attached below the numberplate. I make sure the bolts are tightened securely but even after a short local ride, thats enough for the bolts to loosen. We've put supa-glu on the bolt which made the holder nice and tight, only to have the rego label snap off during a ride. Put another label on this week and already have gone the supa-glu route because it too has vibrated really loose. Theres no where on the left hand rear to attach it to. I've thought about attaching it to my windshield because at least I can keep an eye on it there and its unlikely to snap off, but DMR said that is illegal and the only place is on the rear of the bike. Has anyone else had this problem? My bike doesnt rumble and vibrate THAT much to cause this to happen, and we are at our wits end knowing what to do if this current 3rd label comes off.
