What is EFI on a motorcycle?
In a sense, Electronic Fuel Injection is a lot simpler than a carburetor. Reduced to its essentials an EFI system is nothing more than a nozzle that sprays gasoline into the airstream whenever a computer tells it to.
Is EFI better than carbureted?
Warren Johnson: Properly tuned, carburetors make more peak power than EFI in a Pro Stock engine. A carb’s pressure differential atomizes the gas a lot better than spraying fuel through an orifice. But EFI has a broader powerband and superior cylinder-to-cylinder fuel distribution.
How does the EFI system work?
Electronic fuel injection replaces the need for a carburetor that mixes air and fuel. EFI does exactly what it sounds like. It injects fuel directly into an engine’s manifold or cylinder using electronic controls.
What is the advantage of EFI?
A major benefit of EFI systems is the greatly improved cold and hot starting performance due to its ability to calculate the optimum air/fuel mixture for starting compared to a carbureted system.
What’s the difference between EFI and carburetor?
Aftermarket bolt-on throttle body EFI systems such as this one from MSD are an alternative to replacing an old worn out carburetor with a new or rebuilt carb. A key difference between EFI and a carburetor is that EFI constantly “retunes” itself on the go while a carburetor does not.
How do I change my carburetor to EFI?
How to Complete a Carb-to-EFI Fuel Injection Conversion
- Tools and Materials.
- Remove the Carburetor. Take off the fuel lines and hoses that come from the carburetor.
- Install the Injectors in the Intake Manifold.
- Install the Throttle Body.
- Install the Sensors.
- Adjust the Distributer.
- Set up the Electronics.
Can I convert my carbureted motorcycle to fuel injection?
A carburetor can be converted to fuel injection on a motorcycle or dirt bike by using an EFI (electric fuel injection) kit. The tricky part is finding the right EFI kit for your dirt bike because converting the carburetor is quite simple.
Can you replace carburetor with fuel injection?
A fuel injection conversion replaces a carburetor with a fuel injection system. There are fuel injection conversion kits that make the entire process very easy. Older cars have carburetors, but electronic fuel injection (EFI) offers greater fuel efficiency and improved performance.
What’s the best EFI system for my motorcycle?
While most EFI systems operate in a similar fashion each one is a dedicated design fitted and mapped for a particular motorcycle. Fortunately, there’s plenty of shared hardware to help keep costs manageable. Yamaha, Suzuki and Kawasaki (with some exceptions) all seem to prefer Denso processors in conjunction with Keihin throttle bodies.
How do EFI systems work?
Many EFI’s systems use a Speed-density map at low and cruising speeds where the vacuum system is strong, then switch to an Alpha-N strategy at large throttle openings. In essence, this provides the best of both worlds, which is always a neat trick.
What does EFI stand for on a car?
EFI Basics. In its simplest terms, an electronic fuel injection (EFI) system is a computer controlled fuel delivery system. This electronic control unit (ECU) reads various sensors located on the vehicle and makes the determination of how much fuel to allow the engine to have based on this information.
Why can’t you use fuel from the tank of an EFI bike?
In case of EFI bikes, you might have heard that a certain amount of fuel cannot be used from the tank. This is because when there is no more fuel left to get the desired pressure, the remaining fuel in the pressure pump is rendered useless. Hence the non-usability.
