I'm new to motor bicycles and would appreciate some advice. I just bought an 2003 Gary Fisher Tiburon in great condition. Could anyone advise a 2-stroke kit for the 20 in. frame? I would like a jackshaft kit, but will be happy to start out simple and upgrade as I learn more. Thanks in advance for any tips and recommendations. I look forward to becoming a useful contributor to this forum. Be well and ride safe. J.
