After buying a V-star 1100 shock to lower the bike for my wife & oldest daughter, I've found I want the ability to relatively quickly go back and forth from lowered to stock height. The shock removal / swap is relatively easy, but one of the biggest issues is the cotter pin at the end of the pin on the lower mount. After 2 or 3 flexes these break. I'm wondering why you couldn't use the bolt & lock nut (and washers) that came with the v-star shock. Wondering if it has to be a pin for a specific reason? Any other ideas?
