While repairing the turn signal switch on my old Honda Valkyrie, the ball bearing that acts as a retainer popped out and was lost somewhere on the floor of my garage. Since the turn signal switch is not replaceable, the entire shell and wiring harness will need to be replaced. If only I could find the ball bearing. Well I found. Right here on Amazon. I saved about $100 by replacing the entire assembly. And now I have a spare!
