I have a project that got completely out of hand. It went from painting the pipes and new steering bushings and shims to....COMPLETELY ripped apart.Sand blasted bulk head and stripped and polished the tunnel.Holy crap. Now my question is how much better is the the rear suspention on a 1991 Exciter compared to the 1990? I have both. Both need work and the 1991 needs the most and requires me to drill new mounting holes....as far as I can tell. Is it worth the swap??
