Your capable Harley Davidson is powered by a V-Twin two-cylinder air-cooled motor that produces horsepower by burning the air-and-fuel mixture in the combustion chambers. There are systems responsible for delivering this mixture to the engine, and the ignition system must provide sparks to ignite it at the right moment. This system consists of an ignition switch that turns the motor on, kill switch that turns it off, ignition boxes and modules that manage the spark timing, ignition coils that produce high-voltage impulses, and spark plugs that transform these impulses into sparks. All these components are connected with wires. Some of the circuits are protected from shorts with fuses.
Some of the most typical signs of the ignition system malfunction are rough idling, misfire, hard starts, reduced engine output, and so on. In this case, first and foremost, check your spark plugs. Their electrodes may get burnt or contaminated with carbon deposits reducing their ability to produce sparks. If the plugs are good, check ignition coils, and so on. On the digital shelves of our online store, you can find a full range of Harley Davidson ignition system parts that you may need to restore the operation of your motor. We work with such reputable manufacturers as HardDrive, Daytona Twin Tec, Compu-Fire, Suma X, and many others.
