Harley-Davidson Carburetors & Carb Parts

The world of Harley carburetor tuning is vast. Expert carb tuners are folk heroes and sought after even as EFI machines are now standard. Knowing how to tune a Harley carburetor opens the door to a better performing motorcycle and more enjoyable rides. Over the years, there have been many different carbs used on Harleys. Many of the same principles are the same between the varying carbs and the knowledge you gain on one style can transfer to another.

Many riders look back fondly on the days of all Harleys having carbs. A carburetor is relatively easy to fix compared to an EFI system. In fact, roadside fixes and tunes can easily be done with just a little experience. It’s a simple system but can be made complicated when trying to dial in the perfect jet combination. Fortunately for the carb fans, there are still many older HD’s still on the market that are perfectly fine machines.

Aftermarket Harley carbs are a great option when looking for more performance. Historic brands like S&S, Mikuni and Lectron have made their names on performance carbs. The S&S Super series are a go to for many custom builders. These increase the amount of airflow, which means more power.

The right carb jets are the keys to the kingdom. With the right jet setup, your fuel mixture will provide the ultimate performance. A wrong setup will lead to poor performance and can even lead to dangerous engine performance. And even if you have the right setup, you will need to replace needles and jets at some point. They can be cleaned, but at some point they need to be replaced. Whole carb rebuild kits and parts are available to make your old carb perform like new.
