These generally include some models from the late 1990s to the early 2000s, marked particularly by concerns with the Twin Cam engine and fuel delivery systems. Being aware of these patterns not only ensures you make a more informed decision but also protects the joy and quality of your riding experience. So keep reading, and let’s get into the details so you know exactly what year Harleys to avoid by the end of it!


When you’re exploring the Harley-Davidson range, it’s crucial to be aware of certain model years that are known for specific issues affecting the engine, performance, and electrical system. Let’s take a look at some of these problems you might encounter.

Twin Cam Problems

From 1999 to 2006, the Twin Cam engine became a major concern due to:

  • Heat management: This affected the overall engine performance and could lead to premature component wear.
  • Cam chain tensioners: These parts had a tendency to fail prematurely, potentially causing extensive engine damage.
  • High crank runout: This issue affected the longevity and reliability of the engine.
  • Cam bearing failures: Another common point of contention, leading to costly repairs.

Models with the Twin Cam engine, specifically in the aforementioned years, are ones you might consider avoiding.

Oil Leaks

Harley-Davidson motorcycles, particularly those from the early 2000s, have been plagued by oil leaks. This is mainly a lubrication and maintenance issue, often due to:

  • Improper sealing within the engine.
  • Aged or degraded gaskets after regular use.

Regular maintenance is key in preventing such common issues, yet certain models may exhibit oil leaks more frequently.

Electrical System Issues

On the electrical front, you should keep an eye out for:

  • Infotainment system: Models from recent years had reports of malfunctioning systems which could interfere with the overall riding experience.
  • General electrical problems: Various technical issues stemming from wiring and fuses to more complex components have been reported as common faults.

Your Harley is not just a ride but a complex system where every component plays a role. Being informed can help you steer clear of models that could disrupt your smooth ride.
