The Suzuki Access 125 has long been a favorite in the Indian scooter market, known for its reliability, comfortable ride, and practical features. However, the transition to the BS6 emission standards brought with it a new set of challenges for some owners. While the updated Access 125 Bs6 offers a cleaner engine and improved fuel efficiency, some riders have encountered issues that can be frustrating.

What's the Buzz About? Common Complaints with the Access 125 BS6

Let's dive into some of the most frequently reported problems associated with the Suzuki Access 125 Bs6, exploring potential causes and possible solutions.

1. Starting Troubles (Especially in Cold Weather):

Perhaps the most common complaint revolves around starting the scooter, especially in colder climates or after it has been sitting idle for a few days. This issue can manifest in a few different ways:

  • Engine struggles to turn over: The starter motor may sound weak or hesitant.
  • Engine cranks but doesn't fire: The engine turns over normally, but it refuses to start.
  • Delayed start: The engine takes longer than usual to start.

Possible Causes:

  • Weak Battery: The battery is crucial for starting, especially with the BS6's fuel injection system. A weak or old battery might not provide sufficient power to crank the engine and fire the fuel injectors.
  • Faulty Fuel Injector: The fuel injector is responsible for delivering the correct amount of fuel into the engine. If it's clogged or malfunctioning, it can lead to starting problems.
  • Spark Plug Issues: A worn-out or fouled spark plug can prevent the engine from igniting the fuel-air mixture.
  • Sensor Malfunctions: The BS6 engine relies on various sensors (like the temperature sensor) to optimize performance. A faulty sensor can send incorrect data to the ECU (Engine Control Unit), leading to starting problems.
  • Idle Speed Adjustment: The idle speed might be set too low, causing the engine to stall or struggle to start.
  • Fuel Pump Issues: The fuel pump delivers fuel from the tank to the injector. A failing fuel pump can lead to insufficient fuel pressure, resulting in starting difficulties.

Possible Solutions:

  • Battery Check and Replacement: Have the battery tested by a qualified technician. If it's weak or old, replace it with a new one that meets the scooter's specifications.
  • Fuel Injector Cleaning/Replacement: If you suspect a clogged fuel injector, have it cleaned or replaced by a professional.
  • Spark Plug Replacement: Replace the spark plug with a new one of the correct type and gap.
  • Sensor Diagnosis: Take the scooter to a qualified mechanic to diagnose any potential sensor malfunctions using a diagnostic tool.
  • Idle Speed Adjustment: Have the idle speed adjusted to the correct setting by a mechanic.
  • Fuel Pump Check: A mechanic can check the fuel pump pressure and function to determine if it needs replacement.
  • Choke (If Applicable): Even though it's fuel injected, ensure the automatic choke system is functioning correctly. In some cases, it might not be engaging properly in cold weather.

2. Reduced Fuel Efficiency:

While the BS6 upgrade aimed to improve fuel efficiency, some owners have reported a decrease compared to the older BS4 models.

Possible Causes:

  • Engine Tuning: The BS6 engine is tuned differently to meet stricter emission norms. This can sometimes result in a slight decrease in fuel efficiency.
  • Driving Habits: Aggressive acceleration, frequent braking, and high speeds can significantly reduce fuel efficiency.
  • Tire Pressure: Underinflated tires increase rolling resistance, leading to higher fuel consumption.
  • Air Filter: A clogged air filter restricts airflow, forcing the engine to work harder and consume more fuel.
  • Poor Maintenance: Neglecting regular maintenance, such as oil changes and spark plug replacements, can negatively impact fuel efficiency.
  • Fuel Quality: Using low-quality fuel can also reduce fuel efficiency.

Possible Solutions:

  • Driving Style: Adopt a smoother driving style with gentle acceleration and braking.
  • Tire Pressure: Regularly check and maintain the recommended tire pressure.
  • Air Filter Replacement: Replace the air filter at the recommended intervals.
  • Regular Maintenance: Adhere to the recommended maintenance schedule, including oil changes, spark plug replacements, and other essential services.
  • Fuel Quality: Use high-quality fuel from reputable gas stations.
  • ECU Reset: In some cases, resetting the ECU (Engine Control Unit) can help improve fuel efficiency by allowing it to relearn optimal settings. However, this should be done by a qualified technician.

3. Engine Stalling:

Some riders have experienced the engine stalling, especially at low speeds or when idling.

Possible Causes:

  • Idle Speed: As mentioned earlier, an improperly set idle speed can cause the engine to stall.
  • Fuel Injector: A clogged or malfunctioning fuel injector can lead to inconsistent fuel delivery, resulting in stalling.
  • Sensor Issues: Faulty sensors can disrupt the engine's operation and cause it to stall.
  • Vacuum Leaks: Vacuum leaks in the intake system can disrupt the air-fuel mixture and lead to stalling.
  • Throttle Body Issues: A dirty or malfunctioning throttle body can also contribute to stalling problems.

Possible Solutions:

  • Idle Speed Adjustment: Have the idle speed adjusted to the correct setting by a mechanic.
  • Fuel Injector Cleaning/Replacement: Clean or replace the fuel injector if necessary.
  • Sensor Diagnosis: Have the sensors checked for proper functioning.
  • Vacuum Leak Check: A mechanic can inspect the intake system for vacuum leaks and repair them.
  • Throttle Body Cleaning: Clean the throttle body to ensure smooth airflow.

4. Increased Engine Noise and Vibrations:

Some owners have noticed an increase in engine noise and vibrations compared to the BS4 models.

Possible Causes:

  • Engine Tuning: The BS6 engine is tuned differently, which can sometimes result in slightly increased noise and vibrations.
  • Engine Mounts: Worn or damaged engine mounts can amplify vibrations.
  • Exhaust System: The exhaust system might be resonating or vibrating due to loose components or damage.

Possible Solutions:

  • Engine Mount Check: Have the engine mounts inspected and replaced if necessary.
  • Exhaust System Inspection: Check the exhaust system for loose components or damage and repair them.
  • Professional Inspection: If the noise and vibrations are excessive, take the scooter to a qualified mechanic for a thorough inspection.

5. Sensor Related Issues (Check Engine Light):

The BS6 models are equipped with more sensors, which means there's a higher chance of sensor-related problems triggering the "Check Engine Light" (CEL).

Possible Causes:

  • Faulty Oxygen Sensor (O2 Sensor): The O2 sensor monitors the oxygen content in the exhaust gases. A faulty sensor can trigger the CEL.
  • Faulty Throttle Position Sensor (TPS): The TPS monitors the position of the throttle. A faulty sensor can cause starting problems, stalling, and poor performance.
  • Faulty Temperature Sensor: Incorrect temperature readings can affect fuel mixture and engine performance.

Possible Solutions:

  • Diagnostic Scan: Take the scooter to a qualified mechanic to perform a diagnostic scan to identify the specific sensor that is causing the problem.
  • Sensor Replacement: Replace the faulty sensor with a new one.

Tips to Minimize Potential Problems:

While some problems are unavoidable, there are steps you can take to minimize the likelihood of encountering them:

  • Regular Servicing: Adhere to the recommended servicing schedule and have the scooter serviced by a qualified technician.
  • Use Quality Fuel: Use high-quality fuel from reputable gas stations.
  • Maintain Tire Pressure: Regularly check and maintain the recommended tire pressure.
  • Proper Storage: If you're not using the scooter for an extended period, disconnect the battery to prevent it from draining. Consider using a fuel stabilizer.
  • Avoid Overloading: Avoid overloading the scooter, as this can put excessive strain on the engine and other components.
  • Gentle Riding: Adopt a smooth and gentle riding style.
