Things to Look When Buying a Carburetor for Harley EVO

Undeniably, Harley Davidson is one of the biggest motorcycle brands in the entire world. Of course, not only aesthetics but even the quality appears to be a big deal for the manufacturers. That’s why Harley always offers the best engines, gears, and other equipment.

And regardless of numerous bike models, Harley EVO includes a phenomenal engine. Nevertheless, if not supported with an astounding carb, the engine won’t provide satisfaction. So here are a few important things to consider before buying your EVO’s carb.

A. Quick Throttle Response

If the carburetor has an average throttle response, don’t buy it. Why? Because it helps the engine to respond against the acceleration. So low throttle response means the engine won’t show prompt results on increasing speed.

Moreover, you would face maximum lag time whenever you’ll kick-start your Harley EVO. Therefore, go for the carb that has a fast throttle response.

B. Buy an Easily Tuned Carburetor

Don’t go for the complex structures when finding a carburetor, or half of your life would be gone in the tuning process. We have seen many bikers spending multiple days on tuning carburetors, but getting no satisfactory results.

So remember, always choose a carburetor whose adjustment features, such as air filters and screws, are easiy accessible and simple to tune.

C. Choose Warranty over Inexpensiveness

Buying a cheap carb without a warranty is a waste of money. Such carbs have zero durability and quality. So make sure you purchase the one that has a warranty. Contrarily, go for the one that has majority positive user reviews.


#1. Does carburetor affect fuel mileage?

- A carburetor mixes fuel and air to create accurate combustion. In case, the carb’s air filter is clogged, it may not pass the required airflow. And as a consequence, you get reduced mileage.

#2. When should I change my carburetor?

- If your bike releases black smoke, consumes more fuel, or the engine is backfiring/overheating, then you must change the carb ASAP.

#3. Will a bigger carburetor make my Harley EVO faster?

- Yes! The bigger your carburetor is, the better air and fuel mixture would be. It will cause greater combustion that will increase your bike’s speed and overall performance.

We hope that this article has been helpful to you in choosing the best carb for Harley EVO. So, if you are concerned about mileage, but also desire for increased airflow, tremendous speed, fast throttle response and extraordinary performance, then S&S Cycle Super G Carburetor could be your top-pick.

Conversely, if you’re looking for a carburetor that adds beauty to your EVO and includes all necessary features, such as accelerator pump, standard throttle response, and quick installation process, then we recommend going for Hwbnde HSR 42mm Carburetor Kit.
