Jet (Atomizer BE1 - SI) for Scooters & Mopeds

Atomizer for Scooters and Mopeds

The Atomizer BE1-SI is a component built for a range of scooters and mopeds. It sits in the main jet stack and has small holes along its sides that govern fuel flow. Among the scooter carburetors & jets available, it is one that hobbyists often look at when considering an upgrade or swap for better performance. Each atomizer carries a rating from BE1 to BE5, but those numbers do not indicate a strict ranking of performance.

How It Works

The atomizer fits directly inside the carburetor and affects how fuel moves through the system as the engine runs. Its side holes provide fine control over fuel delivery, which can have a noticeable impact on how the engine behaves. Plenty of riders keep the factory atomizer in place and instead fine-tune the main and air jets to get the setup they want.

Signs It May Need Replacing

If the engine shows performance problems or fuel delivery seems inconsistent, a new atomizer could be worth considering. Routine upkeep and tuning can improve throttle response and efficiency. Getting jetting right usually takes some experimentation, so reviewing jetting guides can help you reach the result you are after.
