I recently had my rear tire changed ('06 Kingpin)at my dealer, in lieu of a 2000 mile ride to Denver and then to Sturgis.I leftMinneapolis andstopped for lunch inLincoln NE. I noticed after lunch that my Tomahawk(axel nut)side mount licence plate was twisted and had sagged down. The bracket had twisted with such force that ithad cut a 1/4" gashwhere my swingarm ismachined grooveand thespacer and axel nut sitIt appeared that someone had stepped on it asto mount my bike. I twisted it back in shape and continued my ride through Nebraska. At every gas stop it rotated(clockwise)and twisted again. In Ogalala NE I called my mechanic and he told me to tighten the axel nut. Having only a Vise gripI did so. Finally(13 Hours, 850 Miles) I reached Denver and the next day scheduled my bike for service. The mechanic reinstalled the missing washer between the nut and mount and spliced new wire for the license light. Thinking maybe I had the problem solved, it hasn't stoppedthe clockwise rotation. Although it has improvedit still wants torotate. Has anyone else experienceda similar problem with a side mount plate holder. I'm thinking the gouge the bracket cut into my swingarm won't hold the bracket properly. I don't know. Someone please help me.
