My good friend Mark Walker is an engineering genius. He's also somewhat of a guru, with a very calm and philosophical air to him. Mark is a self taught engineer, capable of creating machinery beyond the dreams of most people. Mark is also dyslexic. He cant read or write to save himself. All of his designs and schematics come straight out of his head. He's been a good friend of my parents for 40 odd years.
I well remember visiting his home in Sydney and being fascinated by his creations. Everything he builds is bigger and just a little bit different to most other motorcycles. The images will describe this better than I ever could.
