The Dreaded Clutch Basket Woes: A Common Culprit

One of the most discussed and, unfortunately, prevalent issues with the FJR1300, particularly older models (especially pre-2006), revolves around the clutch basket. This component is responsible for transmitting power from the engine to the transmission, and its design in early FJR1300s made it susceptible to wear and tear, leading to some very irritating symptoms.

  • Rattling Noise: The most obvious sign is a distinct rattling or clattering sound emanating from the clutch area, especially at idle with the clutch lever released. This is caused by the fingers of the clutch basket becoming worn and allowing the clutch plates to move excessively.
  • Difficulty Finding Neutral: A worn clutch basket can make it difficult to shift into neutral, especially when the engine is warm. This is because the clutch may not be fully disengaging.
  • Jerky Clutch Engagement: You might experience a jerky or abrupt clutch engagement, making smooth starts and low-speed maneuvers challenging.
  • Increased Vibration: Excessive vibration, particularly felt through the handlebars, can also indicate a failing clutch basket.

The Solution? Replacement is often the best long-term fix. Many FJR1300 owners opt to replace the original clutch basket with a later model or aftermarket version designed with improved durability and reduced play. While this can be a moderately involved job, requiring specialized tools and some mechanical know-how, it's a worthwhile investment for a smoother and more reliable ride. Consider replacing the clutch plates and springs at the same time for optimal performance.

Heat Management: Feeling the Burn?

The FJR1300, with its powerful engine nestled within fairings designed for weather protection, can generate a significant amount of heat, particularly in warmer climates or during stop-and-go traffic. This heat can be uncomfortable for the rider, especially on their legs.

  • Excessive Heat Around Legs: The most common complaint is excessive heat radiating from the engine and exhaust, particularly around the rider's lower legs and thighs.
  • Engine Overheating (Rare but Possible): While less common, in extreme conditions or with a malfunctioning cooling system, the engine could overheat. Keep an eye on your temperature gauge!

What Can You Do? Fortunately, there are several steps you can take to mitigate the heat issue:

  • Install Heat Shields/Deflectors: Aftermarket heat shields or deflectors can redirect heat away from the rider's legs. These are relatively inexpensive and easy to install.
  • Use Ceramic Coating on Exhaust: Applying a ceramic coating to the exhaust system can help reduce radiant heat.
  • Ensure Proper Coolant Levels and Condition: Regularly check and maintain the coolant level and condition. Replace the coolant according to the manufacturer's recommendations.
  • Consider Aftermarket Radiator Fans: Some riders install aftermarket radiator fans with higher flow rates to improve cooling efficiency.
  • Riding Gear: Wearing appropriate riding gear, including pants designed for warm weather riding, can provide a barrier against the heat.
  • Avoid Prolonged Idling: Minimize idling in hot weather to reduce heat buildup.

The Pesky Throttle Position Sensor (TPS): Stalling and Hesitation

The Throttle Position Sensor (TPS) is a crucial component that tells the engine control unit (ECU) how much throttle you're applying. A faulty TPS can lead to various performance issues.

  • Stalling: The engine may stall unexpectedly, particularly at low speeds or when coming to a stop.
  • Hesitation or Stumbling: You might experience hesitation or stumbling during acceleration.
  • Poor Fuel Economy: A faulty TPS can cause the ECU to miscalculate the fuel mixture, leading to poor fuel economy.
  • Check Engine Light (Sometimes): In some cases, a faulty TPS will trigger the check engine light.

Diagnosing and Fixing the TPS:

  • Check for Error Codes: Use a diagnostic tool to check for error codes related to the TPS.
  • Inspect the Wiring and Connector: Ensure the wiring and connector to the TPS are clean and in good condition.
  • Test the TPS with a Multimeter: You can use a multimeter to test the TPS's resistance across its range of motion. Consult the service manual for specific testing procedures and values.
  • Replacement: If the TPS is faulty, replacement is usually the best option.

Generator/Alternator Issues: Keeping the Battery Charged

The generator/alternator is responsible for charging the battery and providing power to the electrical system. Issues with the generator/alternator can lead to a dead battery and other electrical problems.

  • Dead Battery: The most obvious symptom is a dead battery, especially if it keeps happening even after charging.
  • Dim Headlights: Dim headlights can indicate a weak charging system.
  • Error Codes: Some FJR1300s have a charging system warning light or error code that will illuminate if there's a problem.

Troubleshooting the Generator/Alternator:

  • Check the Battery Voltage: Use a multimeter to check the battery voltage with the engine off and with the engine running. The voltage should increase when the engine is running, indicating that the generator/alternator is charging the battery.
  • Inspect the Wiring and Connections: Check the wiring and connections to the generator/alternator for corrosion or damage.
  • Test the Generator/Alternator Output: A mechanic can test the generator/alternator's output to determine if it's producing the correct voltage and current.
  • Replacement: If the generator/alternator is faulty, replacement is necessary.

Suspension Woes: Sagging and Bouncing

The FJR1300's suspension is designed to provide a comfortable and controlled ride. However, over time, the suspension components can wear out, leading to a degraded ride quality.

  • Sagging Suspension: The suspension may sag excessively, particularly under load.
  • Bouncing or Harsh Ride: The ride may become bouncy or harsh, especially over bumps.
  • Leaking Fork Seals: Leaking fork seals are a common problem, indicating that the seals need to be replaced.

Addressing Suspension Issues:

  • Adjust Suspension Settings: Ensure the suspension settings are properly adjusted for your weight and riding style.
  • Replace Fork Oil and Seals: Replacing the fork oil and seals is a routine maintenance task that should be performed periodically.
  • Consider Upgrading Suspension Components: If you're looking for improved performance, consider upgrading the suspension components with aftermarket springs, dampers, or even a complete suspension system.

The Infamous Fuel Pump: A Potential Showstopper
