For decades, Harley-Davidson has been a force to be reckoned with in the American motorcycle scene. Throughout its history, Harley has made many advancements in motorcycle technology to keep up with changing times and customer demands. One of the most significant changes came in the late 1990s when Harley switched from carburetors to electronic fuel injection (EFI) on many of its models. In this article, we'll delve into the specifics of when Harley made the switch and what it meant for riders.
The Carburetor Era
Before we dive into the EFI era, let's take a quick look at the carburetor era that preceded it. Harley used carburetors on its motorcycles for many years, with the earliest models dating back to the 1930s. Carburetors work by mixing fuel and air in a chamber, then delivering the mixture to the engine's cylinders. These early carburetors were simple devices that required occasional tuning to keep the engine running smoothly.
Over time, carburetors became more advanced, with features like automatic choke, accelerator pumps, and adjustable jets. However, they still had their limitations. Carburetors were sensitive to changes in altitude and temperature, which could affect the air/fuel mixture and cause the engine to run poorly. They also tended to be less fuel-efficient than modern fuel injection systems.
The EFI Revolution
The Early Years
Harley's first EFI system debuted on the 1995 FLHTC Electra Glide Classic. This system used a single throttle body with a single injector to deliver fuel to the engine. The system was simple but effective, and Harley continued to refine it in the years that followed. By the late 1990s, most of Harley's big V-twin models were available with EFI as an option.
The benefits of EFI over carburetors were numerous. EFI systems could automatically adjust the air/fuel mixture based on temperature, altitude, and other factors, ensuring optimal performance in all conditions. They also tended to be more fuel-efficient, which was becoming increasingly important as gas prices rose. EFI systems were also easier to start in cold weather, as the system could automatically enrich the fuel mixture for easier cold starts.
The Modern Era
Today, all of Harley's big V-twin models come standard with EFI. Modern EFI systems are more advanced than ever, with features like multiple injectors per cylinder, individual cylinder mapping, and ride-by-wire throttle control. These systems are capable of delivering precise amounts of fuel to the engine at all times, ensuring optimal performance and fuel efficiency.
Overall, the switch to EFI was a major milestone for Harley-Davidson. It allowed the company to keep up with changing times and customer demands while maintaining the classic Harley look and feel. Today, Harley's EFI systems are some of the most advanced in the world, and they continue to push the boundaries of motorcycle technology.
Conclusion
So, when did Harley go to fuel injection? The answer is, it depends on the model. Harley's first EFI system debuted on the 1995 FLHTC Electra Glide Classic, but it wasn't until the late 1990s that most of Harley's big V-twin models were available with EFI as an option. Today, all of Harley's big V-twin models come standard with EFI, and the systems are more advanced than ever. Whether you're a die-hard carburetor fan or a modern EFI enthusiast, there's no denying the impact that EFI has had on the Harley-Davidson brand.
