Replacing the ignition switch on my '72 R75/5. "There is an elliptical band spring that holds a ball bearing on the internal shaft" from a post long ago by James A. (you still out there James?). I can see where the ball bearings fit into the shaft. I received 2 elliptical band springs with the kit I bought from "Boxer 2-Valve (Wunderlich America)". One spring has a clean split, on the other the end edges are flared in. My dilemma is, ( other than the "sproing" when I took the original switch out ), do I use both of the band springs maybe one inside the other or, what is the correct assembly? Many thanks.
