The Kawasaki Concours 1400, a sport-touring motorcycle celebrated for its powerful engine and comfortable long-distance capabilities, isn't without its quirks. While reliability is generally good, certain issues tend to surface more frequently than others, potentially impacting the riding experience and ownership costs. Understanding these common problems allows potential buyers and current owners to be proactive in maintenance and troubleshooting, ultimately keeping their Concours 1400 on the road and performing at its best.

What Are the Most Common Concours 1400 Issues?

Several recurring issues plague the Concours 1400, ranging from minor annoyances to more significant mechanical concerns. Addressing these proactively can save you time, money, and frustration in the long run. Let's dive into some of the most frequently reported problems:

1. Throttle Position Sensor (TPS) Issues:

One of the most well-documented issues affecting the Concours 1400 is related to the Throttle Position Sensor (TPS). The TPS is responsible for telling the engine control unit (ECU) the throttle position, which is crucial for proper fuel injection and ignition timing. When the TPS malfunctions, it can lead to a variety of symptoms, including:

  • Rough idling: The engine may idle erratically, surging or dropping in RPM.
  • Hesitation or stalling: The bike may hesitate or stall, especially during acceleration from a stop or at low speeds.
  • Poor fuel economy: Incorrect TPS readings can cause the engine to run rich or lean, impacting fuel efficiency.
  • Check engine light: The malfunction indicator lamp (MIL) may illuminate, indicating a problem with the TPS circuit.

Why does this happen? Heat and vibration seem to contribute to TPS failures. The sensor itself can become worn or corroded over time, leading to inaccurate readings.

What can you do?

  • Regularly inspect the TPS: Check for any signs of damage or corrosion.
  • Clean the TPS connector: Use electrical contact cleaner to remove any dirt or debris from the connector.
  • Consider a TPS replacement: If you're experiencing persistent TPS-related issues, replacing the sensor might be necessary. After replacement a TPS adjustment is often necessary, this is best done with a Kawasaki specific scan tool.

2. Clutch Slave Cylinder Leaks:

Another common problem involves the clutch slave cylinder. The slave cylinder is responsible for actuating the clutch when you pull the clutch lever. Over time, the seals within the slave cylinder can wear out, leading to leaks. Symptoms include:

  • Loss of clutch fluid: You may notice a decrease in the fluid level in the clutch reservoir.
  • Difficulty shifting: Shifting gears may become difficult or impossible due to insufficient clutch engagement.
  • Clutch slipping: The clutch may slip, especially under heavy acceleration.
  • Visible fluid leaks: You may see fluid leaking from the slave cylinder itself.

Why does this happen? The seals inside the slave cylinder are exposed to heat and pressure, which can cause them to deteriorate over time.

What can you do?

  • Inspect the slave cylinder regularly: Look for any signs of leaks.
  • Replace the slave cylinder seals: A rebuild kit with new seals is often a more cost-effective solution than replacing the entire slave cylinder.
  • Upgrade to an aftermarket slave cylinder: Some riders opt for aftermarket slave cylinders with improved seals and construction.

3. Tire Pressure Monitoring System (TPMS) Issues:

Many Concours 1400 models are equipped with a Tire Pressure Monitoring System (TPMS). While TPMS can be helpful, it can also be a source of frustration. Common issues include:

  • False readings: The TPMS may display inaccurate tire pressure readings.
  • Sensor failures: The sensors themselves can fail, requiring replacement.
  • Battery depletion: The batteries in the TPMS sensors eventually need to be replaced.
  • Warning light: The TPMS warning light may illuminate even when the tire pressure is correct.

Why does this happen? TPMS sensors are exposed to harsh conditions, including heat, vibration, and moisture. The batteries also have a limited lifespan.

What can you do?

  • Regularly check your tire pressure manually: Don't rely solely on the TPMS.
  • Replace the TPMS sensors when necessary: If a sensor fails or the battery is depleted, replace it with a new one.
  • Consider disabling the TPMS: If you're experiencing persistent TPMS problems and don't find it helpful, you can disable the system. Note that disabling the TPMS might have legal implications in some jurisdictions.

4. Fuel Pump Problems:

Although less frequent than the other issues, fuel pump problems can still occur. The fuel pump is responsible for delivering fuel from the fuel tank to the engine. If the fuel pump fails, it can cause the engine to stall or not start at all. Symptoms include:

  • Engine stalling: The engine may stall, especially under heavy acceleration or at high speeds.
  • Difficulty starting: The engine may be difficult to start, or it may not start at all.
  • Fuel starvation: The engine may run lean due to insufficient fuel delivery.
  • Whining noise: You may hear a whining noise coming from the fuel tank.

Why does this happen? The fuel pump can become clogged with debris from the fuel tank, or the pump motor can wear out over time.

What can you do?

  • Use high-quality fuel: Avoid using fuel that may contain contaminants.
  • Replace the fuel filter regularly: A clogged fuel filter can strain the fuel pump.
  • Consider a fuel pump replacement: If you suspect that the fuel pump is failing, replacing it is the best course of action.

5. Regulator/Rectifier Failure:

The regulator/rectifier is responsible for converting the AC voltage from the stator to DC voltage and regulating the voltage to charge the battery. A failing regulator/rectifier can lead to a dead battery and other electrical problems. Symptoms include:

  • Battery not charging: The battery may not charge properly, leading to a dead battery.
  • Overcharging: The battery may be overcharged, which can damage the battery and other electrical components.
  • Dim headlights: The headlights may be dim due to insufficient voltage.
  • Erratic electrical behavior: You may experience other electrical problems, such as flickering lights or malfunctioning gauges.

Why does this happen? The regulator/rectifier is exposed to heat, which can cause it to fail over time.

What can you do?

  • Check the voltage at the battery: Use a multimeter to check the voltage at the battery while the engine is running. It should be between 13.5 and 14.5 volts.
  • Inspect the regulator/rectifier: Look for any signs of damage, such as burnt wires or a melted housing.
  • Replace the regulator/rectifier: If you suspect that the regulator/rectifier is failing, replacing it is the best course of action. Many owners upgrade to aftermarket units with better heat dissipation.

6. Exhaust Heat Issues:

The Concours 1400, especially earlier models, are known for producing a significant amount of heat, particularly around the rider's legs. This heat can be uncomfortable, especially in hot weather.

Why does this happen? The catalytic converter and the engine design contribute to the excessive heat.

What can you do?

  • Install aftermarket exhaust: Aftermarket exhausts often run cooler than the stock exhaust.
  • Install heat shields: Heat shields can help to deflect heat away from the rider's legs.
  • Wear appropriate riding gear: Wear clothing that provides good ventilation and heat protection.
  • Ceramic coating: Applying ceramic coating to the exhaust system can help reduce radiated heat.
