Dirt Bike Carburetor Jets

Dirt bike carburetor jets are precision metering components that control fuel flow through specific circuits of the carburetor, including main jets, pilot jets, and needle jets. They are commonly replaced or upgraded when retuning a carburetor for altitude, temperature changes, or modifications to the air intake or exhaust.

Jet sizing is specific to the carburetor brand and model, and selecting the correct size requires knowing the existing configuration and the direction of desired fuel mixture adjustment. Jets are small, affordable, and often purchased in sets to allow for on-the-fly tuning.
