The short answer is for more and smoother engine power. As the question implies, you’d think that by only having one carb would be simpler for tuning and operating an engine. And at some level that’s true.
Why do motorcycles still use carburetors?
To start with, carbs pollute. Not the way most people think, though. Carburetors may put out a little more pollution through the tailpipe than fuel injection, but the bigger difference is when the bike isn’t running. Carburetors have a bowl in which fuel sits, and that fuel evaporates.

Why are carburetors not used anymore?
Most car manufacturers stopped using carburetors in the late 1980’s because newer technology was coming out, such as the fuel injector, that proved to be more efficient. There were only a few cars that continued to have carburetors, such as the Subaru Justy, until about the early 1990’s.
Are motorcycles still carbureted?
Carburetors are your old-school, analog option, and they’re what all bikes relied on until electronic fuel injection began to appear in the ’80s. Nowadays, the vast majority of bikes have EFI, though plenty of smaller motorcycles and scooters still use carbs to help keep them affordable.
Can you convert a carburetor to fuel injection on a motorcycle?
Modern motorcycles have computer controlled fuel injectors. You can also convert an older motorcycle into a fuel injection system with motorcycle fuel injection conversion kits. … If you prefer, you can convert from carbureted to fuel injection (otherwise known as carb to efi).
What are the 3 types of carburetors?

How much is a carburetor for a motorcycle?
Depending on the extent of service that needs to be performed, this type of service typically costs around $200 to $300. If your carburetor needs to be replaced, it may run you between $500 and $800 total. Carburetor cleaning isn’t as complex an undertaking as you might imagine.
What replaced carburetors?
The first electronic fuel injection systems, using a throttle-body injector, simply replaced the carburetor. Port fuel injection placed individual fuel injectors closer to each intake valve, which powers the majority of modern automobiles.
Does a bigger carburetor mean more power?
The smaller carb has increased air/fuel velocity at low and midrange, giving better throttle response. A larger carb will flow more air/fuel at higher rpm and give more top end and higher peak hp.
What are the best carburetors?

What is a 4 barrel?
A four-barrel carburetor has two primary and two secondary barrels. At idle and low-rpm driving, only the primary barrels open. The throttle blades on the secondary barrels stay closed. … As the secondary barrels begin to open, more air travels through the carburetor, supplying the engine with the air and fuel it needs.
Which is better EFI or carburetor?
EFI systems are more fuel-efficient than carbureted engines. This is because the electronic system constantly adjusts the air to fuel ratio to ensure that optimal levels are delivered. Carbureted engines, on the other hand, may deliver an excess fuel to air ratio, which can lead to more fuel consumption.
Do any cars still use carburetors?
Fuel injection technology has largely supplanted carburetors in the automotive and, to a lesser extent, aviation industries. Carburetors are still common in small engines for lawn mowers, rototillers, and other equipment.
What makes more power carb or EFI?
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.
