A motorcycle ignition system comprises a set of parts which are critical for starting your bike. Spark plug wires provide a link between the vital components as they transport electrical power from the coil to the spark plug. These wires need to function properly to ensure normal engine operation. A number of motor problems may arise if they are faulty. The symptoms associated with the malfunction of these components include rough idle, hesitation, reduced power, and surging. Although the wires are rather durable, their continual exposure to temperature extremes may cause damage to rubber insulation.
When inspecting these wires on your bike, make sure that the engine is off. Considering the high voltage going through them when the motor is running, you may have a serious jolt through the broken insulation. Some Harley Davidson riders tend to change their spark plug wires for better looks or increased performance. However, owners should be careful, because performance wires sometimes lead to faulty codes appearing on a computer. If you need reliable replacements for your bike, look no further. We carry a diverse collection of Harley Davidson motorcycle spark plug wires manufactured to be strong, durable, and resist extreme vibrations.
