A motorcycle engine guard is disclosed which comprises a bar that surrounds the engine of the motorcycle. The auger turbine includes a generally helical turbine blade rotatably mounted on a central shaft, which may be tapered at each end, and a flange extending perpendicularly to an edge of the turbine blade. The memory storage device controller can cause the data having the recoverable information to be rewritten on the memory storage device. During the non-active period, the common electrode drive circuit provides a common electrode signal whose potential changes between LV3 and LV4 to the common electrode, based on a reversal timing control signal. Periodic voltages are applied to electrodes in the first set of electrodes to generate a first oscillating electric potential that radially confines the ions in the ion channel, and periodic voltages are applied to electrodes in the second set of electrodes to generate a second oscillating electric potential that axially confines the ions in the ion channel. An opposite end of the struts is pivotally mounted on a suction cup pivot pin.
