**2004 Road King Problems: A Comprehensive Guide** The Harley-Davidson Road King is a classic American motorcycle that has been in production since 1994. It is known for its iconic styling, powerful engine, and comfortable ride. However, like all motorcycles, the Road King is not without its problems. **1. Electrical Problems:** One of the most common problems with the 2004 Road King is electrical issues. These can range from minor annoyances, such as flickering lights, to more serious problems, such as a dead battery or a complete electrical failure. Common electrical problems include: * **Stator Failure:** The stator is a component of the motorcycle's charging system that generates electricity. If the stator fails, the motorcycle will not be able to charge its battery, which can lead to a dead battery and a motorcycle that won't start. * **Voltage Regulator Failure:** The voltage regulator is a component of the motorcycle's charging system that controls the voltage output of the stator. If the voltage regulator fails, it can cause the stator to overcharge the battery, which can damage the battery and lead to a fire. * **Wiring Harness Issues:** The wiring harness is a complex network of wires that connects the motorcycle's electrical components. If the wiring harness is damaged or loose, it can cause a variety of electrical problems, such as flickering lights, a dead battery, or a complete electrical failure. **2. Fuel System Problems:** Another common problem with the 2004 Road King is fuel system issues. These can range from minor annoyances, such as a rough idle, to more serious problems, such as a complete loss of power. Common fuel system problems include: * **Fuel Injector Problems:** The fuel injectors are responsible for delivering fuel to the engine. If a fuel injector fails, it can cause the motorcycle to run rough, hesitate, or stall. * **Fuel Pump Problems:** The fuel pump is responsible for delivering fuel from the fuel tank to the fuel injectors. If the fuel pump fails, the motorcycle will not be able to run. * **Fuel Filter Problems:** The fuel filter is responsible for removing impurities from the fuel. If the fuel filter is clogged, it can restrict the flow of fuel to the engine, which can cause the motorcycle to run rough or stall. **3. Engine Problems:** Engine problems are also relatively common with the 2004 Road King. These can range from minor annoyances, such as a ticking noise, to more serious problems, such as a blown head gasket. Common engine problems include: * **Excessive Oil Consumption:** The 2004 Road King is known for consuming more oil than other Harley-Davidson models. This is usually not a major problem, but it can be annoying and can lead to a decrease in performance. * **Blown Head Gasket:** A blown head gasket is a serious problem that can cause the engine to overheat and seize. This can lead to catastrophic engine damage. * **Piston Ring Problems:** Piston ring problems can cause the engine to lose compression, which can lead to a decrease in power and performance. **4. Transmission Problems:** Transmission problems are also relatively common with the 2004 Road King. These can range from minor annoyances, such as a noisy transmission, to more serious problems, such as a complete loss of gears. Common transmission problems include: * **Noisy Transmission:** A noisy transmission is usually caused by worn gears or bearings. This can be annoying, but it is usually not a major problem. * **Slipping Gears:** Slipping gears is a more serious problem that can make it difficult or impossible to shift gears. This can be caused by worn gears, a faulty clutch, or a problem with the transmission linkage. * **Complete Loss of Gears:** A complete loss of gears is the most serious transmission problem. This can be caused by a broken gear, a failed transmission shaft, or a problem with the transmission case. **5. Suspension Problems:** Suspension problems are also relatively common with the 2004 Road King. These can range from minor annoyances, such as a rough ride, to more serious problems, such as a broken shock absorber. Common suspension problems include: * **Worn Shocks:** Worn shocks can cause the motorcycle to ride rough and handle poorly. This can be especially noticeable when riding over bumps or rough roads. * **Leaking Forks:** Leaking forks can cause the motorcycle to handle poorly and can also lead to a decrease in performance. * **Bent Forks:** Bent forks can cause the motorcycle to handle poorly and can also be dangerous. **Conclusion:** The 2004 Road King is a great motorcycle, but it is not without its problems. The most common problems include electrical issues, fuel system problems, engine problems, transmission problems, and suspension problems. If you are considering buying a 2004 Road King, be sure to do your research and be aware of the potential problems that you may encounter.
