Have you guys seen Leno's Y2K jet bike? "Boasting over 300 horsepower and 425 ft/lbs of torque...Rolls Royce Allison 25O-C18 Turbine, originally designed for helicopters, was modified and mounted upside down in the frame. It feeds on anything that burns. Fresh out of jet fuel? Just serve it up some diesel or kerosene! If it burns and you can pour it in the tank, the engine will run."
