Hello, I recently met a fella that just bought his 1st vw trike. It has a narrow Kawasaki triple tree. He also has a Kawasaki Vulcan with a wide front end. He said the triple tree pivot pins are the same diameter and length so that he can exchange the wide front end for the narrow one. If this is correct, does anyone know where I can find a chart of pivot pin lengths and diameters that will show what front end would change out with my '84 Yamaha Virago narrow front end? Thanks for your time.
