What is the difference between carburetors and fuel injection?
• Carburettors are completely mechanical devices, but fuel injection can be either mechanical or electronic. However, the electronic fuel injection (EFI) has become the most used. • Carburettors are very complex, and specific experience is required for maintenance and tuning, but fuel injection mechanisms are simpler.
Can you replace a carb with fuel injection?
Unless you have very specific needs swapping to fuel injection is not worth the hassle. No, but you can replace the motorcycle with one that doesn't have a carburetor. It would be way more effort and expense to re work an old carburetor engine to be fuel injected, than to just buy a newer bike that came with it.
Did fuel injection replace carburetors?
Why did we switch from carburetor to fuel injection? Fuel injection, because it can be more precisely controlled, results in more efficient use of fuel, reduced fuel consumption and fewer emissions, which is the main reason it began to replace the carburetor in the 1970s.
How do you check if fuel is getting carburetor?
- Locate the rubber fuel hose that runs from the fuel pump to the carburetor.
- Install the proper size hose fittings in each end of the pressure regulator.
- Place a hose clamp over each end of the fuel hose.
- Tighten the hose clamps.
- Test drive the vehicle to make sure there is adequate pressure to run it on the road.

What are the disadvantages of fuel injection?
Disadvantages of a fuel injection system : The fuel injection system is a lot more expensive than a carburettor upgrade. Repairing fuel injectors is not easy as compared with carburettors. The Air fuel ratio and mix of that will be excellent in a carburettor than a direct Injection system.
Do carburetors make more power?
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.
Does EFI improve MPG?
With EZ-EFI, the exact same mileage loop brought home 18.5 mpg. So there you go-FAST's EZ-EFI is a bolt-on that works, goes on easily, returns better fuel mileage, and in some cases might squeak out a few more horsepower. When it comes to electronic fuel injection, it just doesn't get any easier.
Does Holley EFI add horsepower?

Why do carburetors work?
Carburetors can be made to work well, but only because they are a combination of kludges with overlapping effects, each one needing tweaking which changes something else. Fuel injection has a few sensors and just figures out how much fuel to supply. The most important thing is FEEDBACK.
Do fuel lines need to be changed?
The fuel rails or fuel lines need changed at least for the last few feet. The ignition system needs to no longer be computer controlled. That might mean an MSD style ignition box or just a coil and distributor swap, it depends on the engine and what it originally had.
