That would be a cool project! A Kawasaki KZ (no matter what size) is a simple bike, and is easy to build. Ive been having problems finding parts for my bike, but all the normal-wear stuff is still available. Plus, these bikes run a parallel-twin engine. If you can't have a Harley, that parallel-twin exhaust note is the next best thing. Hopefully gonna have a mini-Triumph to enjoy when Im done. Lol
