MOTOR PERFORMANCE
All stepper motors exhibit instability at their natural frequency and harmonics of that frequency. Typically, this instability occurs at speeds between 50 and 500 full steps per second and, depending on the dynamic motor load parameters, cause excessive velocity modulation or improper positioning. This type of instability is represented by the open area at the low end of each Torque vs. Speed curve. There are also other instabilities that cause a loss of torque at stepping rates outside the range of natural resonance frequencies. One such instability is broadly defined as mid-range instability. Usually, the damping of the system and acceleration/ deceleration through the resonance areas aid in reducing instability to a level that provides smooth shaft velocity and accurate positioning. If instability does cause unacceptable performance under actual operating conditions, use the following techniques to reduce velocity modulation.

The A.C.A. Hurricane I30 siren is thft most powerful siren manufactured in the United States. The output cf I30 decibels at 100 feet is radiated
through the computar designed horn to an effective 70 DB. range of 65OO feet, thus giving a total circular coverage of 05 square miles p^r
siren unit. (Federal CD Guide, March 196/J Installation of the siren is faciliated through the use of the swing down feature. This feature pernits raising and lowering-of the head and horn assembly for installation or major repairs, often times without the need of an external crane» The self-contained, weatherproof electrical control compartment requires that only two electrical connections be made - the signal source and the mai» power source.

6-SPEED TRANSMISSION WITH DD6 RSD TECHNOLOGY
The BAKER RSD DD6 transmission provides smoother shifting, positive neutral-finding, and reduced cruising RPM on the highway as compared to the stock 5-speed. With proven technology and helical 4th, 5th, and 6th gears, town and highway cruising is noise-free. No disassembly of the stock 5-speed is required.

RIGHT SIDE DRIVE
Right side drive is the critical variable in the equation of balancing a fat tire custom motorcycle. Left side drive fat tire bikes rely on offsetting (moving over) the engine, transmission, and/or the primary drive which moves the powertrain center-of-mass to the left and creates an inherent balance bias to the left. Left turn and right turn body English is noticeably different with left side drive; no so with right side drive

Once the engine has started, quickly move the choke lever into the run (front) position. After engine is started, let it warm up for 2-3 minutes before riding. New riders tend to have more trouble turning than more experienced riders do. The best way to learn to make smooth, safe turns is to practice. Defer increased speeds until you are confident of your proficiency and are intimately familiar with the terrain. Your body must be in the right position in order for you to properly control your vehicle. Keep your body fairly erect.
