The Kawasaki Drifter, with its distinctive art deco styling reminiscent of Indian motorcycles, carved a unique niche in the cruiser market. While undeniably eye-catching, these bikes, especially the earlier models, aren't without their quirks. Understanding the potential problems that can arise with a Drifter is crucial for both prospective buyers and current owners, ensuring a smoother and more enjoyable riding experience. Let's dive into some common issues and how to tackle them.

So, What Are the Most Common Drifter Headaches?

Drifters, particularly those manufactured in the late 1990s and early 2000s, are susceptible to a few recurring problems. These range from relatively minor annoyances to more serious issues that require professional attention. Being aware of these potential pitfalls allows you to diagnose problems early and prevent further damage.

Fuel Injection Foibles (Especially on the 1500)

The fuel injection system on the Drifter 1500, while generally reliable, can be a source of frustration.

  • Idle Issues: Many owners report problems with inconsistent or fluctuating idle speeds. This can manifest as the engine struggling to maintain a steady idle when warm, or even stalling at stoplights.
    • The Fix: The most common culprit is a dirty or malfunctioning Idle Air Control (IAC) valve. Cleaning the IAC valve with carburetor cleaner often resolves the issue. If cleaning doesn't work, replacement is usually necessary. Additionally, ensure the throttle position sensor (TPS) is properly calibrated.
  • Fuel Pump Problems: The fuel pump, located inside the fuel tank, can be prone to failure, especially on older models. Symptoms include difficulty starting, poor performance at higher speeds, and a whining noise from the fuel tank.
    • The Fix: Replacing the fuel pump is the most reliable solution. Consider upgrading to an aftermarket pump known for its reliability. Check the fuel filter as well, as a clogged filter can put extra strain on the pump.
  • Lean Running Conditions: Some Drifters exhibit lean running conditions, characterized by popping in the exhaust on deceleration and a lack of power, particularly at higher RPMs.
    • The Fix: This can be caused by vacuum leaks in the intake system, a faulty oxygen sensor, or even incorrect fuel mapping. Thoroughly inspect all vacuum lines for cracks or leaks. Check the oxygen sensor's operation. If necessary, a fuel injection module (like a Power Commander) can be used to fine-tune the fuel mixture.

Cooling System Concerns: Keeping Your Drifter Cool Under Pressure

The Drifter's air-cooled engine relies on an oil cooler to help dissipate heat. However, some owners have reported overheating issues, particularly in hot climates or during slow-speed riding.

  • Oil Cooler Clogging: The oil cooler can become clogged with debris, restricting oil flow and reducing its cooling efficiency.
    • The Fix: Regularly inspect and clean the oil cooler fins. A soft brush and compressed air can be used to remove dirt and debris. Ensure the cooler is not bent or damaged, which can also restrict airflow.
  • Low Oil Level: Maintaining the correct oil level is crucial for proper cooling. Low oil levels reduce the oil's ability to absorb and dissipate heat.
    • The Fix: Regularly check the oil level and top it off as needed. Use the recommended oil type and viscosity for your Drifter.
  • Radiator Fan Issues (if equipped): While not all Drifters have a radiator fan, some aftermarket modifications might include one. If present, ensure it's functioning correctly.
    • The Fix: Check the fan motor, wiring, and temperature sensor. Replace any faulty components.

Electrical Gremlins: When the Lights Go Out (or Act Funny)

Like many motorcycles, the Drifter can experience electrical issues, ranging from minor annoyances to more serious problems that can leave you stranded.

  • Charging System Problems: The charging system, consisting of the stator, regulator/rectifier, and battery, can be a common source of trouble. Symptoms include a weak battery, difficulty starting, and dimming lights.
    • The Fix: Test the stator output voltage and the regulator/rectifier output voltage using a multimeter. Replace any faulty components. Ensure the battery is in good condition and properly charged.
  • Wiring Harness Issues: The wiring harness, especially in older models, can be prone to corrosion and damage, leading to intermittent electrical problems.
    • The Fix: Carefully inspect the wiring harness for any signs of damage or corrosion. Repair or replace any damaged wires or connectors. Use dielectric grease on all electrical connections to prevent corrosion.
  • Fuses Blowing: Repeatedly blowing fuses indicates a short circuit in the electrical system.
    • The Fix: Identify the circuit that is blowing the fuse and trace the wiring to locate the short. Repair or replace any damaged wiring.

Cosmetic Concerns: Keeping Your Drifter Looking Sharp

While not directly affecting performance, maintaining the Drifter's unique appearance is important to many owners.

  • Paint Fading and Chipping: The paint on the Drifter, particularly on the fenders and fuel tank, can be prone to fading and chipping, especially with exposure to sunlight and harsh weather conditions.
    • The Fix: Regular waxing and polishing can help protect the paint. Touch-up paint can be used to repair minor chips and scratches. For more extensive damage, professional repainting may be necessary.
  • Chrome Pitting: The chrome on the Drifter can be susceptible to pitting and corrosion, especially in areas exposed to moisture and salt.
    • The Fix: Regular cleaning and polishing with chrome polish can help prevent pitting. For existing pitting, chrome polish and fine steel wool can be used to remove surface rust. In severe cases, re-chroming may be necessary.

Specific Model Year Quirks

It's worth noting that certain model years of the Drifter have specific issues that are more prevalent. Researching the particular year of your Drifter can help you anticipate potential problems. For example, early 1500 models were known to have more fuel injection issues than later models.

Preventative Maintenance: The Key to a Happy Drifter

The best way to avoid these problems is through regular preventative maintenance. This includes:

  • Regular Oil Changes: Adhere to the recommended oil change intervals.
  • Air Filter Maintenance: Clean or replace the air filter regularly.
  • Spark Plug Inspection: Inspect and replace spark plugs as needed.
  • Fuel System Cleaning: Use a fuel system cleaner periodically to keep the injectors clean.
  • Battery Maintenance: Keep the battery terminals clean and the battery properly charged.
  • Tire Pressure Monitoring: Maintain proper tire pressure for optimal handling and tire life.
  • Thorough Inspections: Regularly inspect the bike for any signs of wear or damage.

Modifying Your Drifter: Proceed with Caution

While modifications can enhance the Drifter's performance and appearance, it's important to choose modifications carefully and ensure they are properly installed. Poorly chosen or installed modifications can exacerbate existing problems or create new ones. For example, installing an aftermarket exhaust system without properly adjusting the fuel injection can lead to lean running conditions.

Fortunately, a strong community of Drifter owners exists online. Forums and social media groups are excellent resources for finding information, sharing experiences, and getting help with troubleshooting problems. Online parts retailers specializing in Kawasaki motorcycles can also be a valuable source for replacement parts.
