��ALL modern motorcycles are equipped with the latest conveniences for start- ^ ing the motor and for operating the brakes and clutch. This places the older machines, however good, in the antiquated class and makes them seem of little value compared with the newer machines. I did not care to sell my old machine at a very reduced price simply because it was not provided with modern equipment, as it served its purpose well. To bring it up-to- date in equipment I added a step or pedal starter, attached footboards, put on a foot- brake and a foot-operated clutch, and now

��into one edge like a saw. The other edge of the band is beveled as at A to prevent catching on the chain. The band is made of a piece of metal about 3^ in. thick and I in. wide with the length the same as the measurement of the circumference of the clutch-rim.

After cutting the teeth and beveling the edge it is riveted in place on the clutch-rim. The holes on the inside should be counter- sunk so that the rivets, when hammered down, will not catch on the clutch-plates. It is preferable to have the piece welded to form a complete band; but it is not neces-

���Details of the clutch band and the attachment of the crank so that a pin will turn the engine shaft by a push on the pedal pin. The construction of the footboard supports

��it compares favorably with a new machine. It is necessary to have projections on the clutch for engaging the catch on the pedal starter. These are applied in the form of a band, shown in Fig. i, having teeth cut

��sary to do so as the rivets will hold it in place.

The left crank is then bent back so that the hole for the pedal is directly opposite the toothed band, as shown in Fig. 2. A
