Best Aluminum Powersports Carburetors in 2026

Most riders settle for restrictive, hard-to-tune stock carburetors that choke out engine potential, but the S&S Super E changes the game with a massive 1 7/8" butterfly throat. I love how much thought went into the ergonomics here. The idle mixture screw is angled perfectly so you aren't fighting for clearance even when running a 5-gallon tank. Instead of a traditional choke that obstructs airflow, this unit uses a clever enrichment device controlled by a lever on your air cleaner backplate for foolproof warm-ups. It is a highly customizable piece of hardware, allowing you to swap intermediate and main jets to dial in your performance. Plus, the included formed fuel line with a 90-degree bend makes for much cleaner, more direct routing in your engine bay.

Harley riders looking to reclaim lost throttle response on their Sportster or Big Twin engines need to stop settling for lackluster factory fueling.

The kit is incredibly comprehensive, arriving with everything from the chrome air filter housing and intake manifold to spare jets and necessary gaskets. Whether you are running a 93-99 Evo Big Twin or another high-performance setup, this kit provides the precision tuning required for a smooth ride. Just keep in mind that this setup is not compatible with Magneto models.
