Take a look at the pic of my wife's 1100: the circled area is where it's loose and the blinker rotates. When she rides, the blinker ends up pointing up about 30 degree angle. How in the world do I tighten it down?
The bolt at the 10 o'clock,(pic) on the OEM post there is a radius on the 90Deg., and that bolt goes thru it an keeps it from rotating and from moving back and forth.
It's unknown as what is used here?
