Common questions
What is the function of a #50 pilot jet?
The pilot jet, like this #50, controls the fuel delivered at idle and very slight throttle openings. It's crucial for smooth starting, stable idle, and a good transition when you first open the throttle.
Will this fit my Harley Big Twin or Sportster with a Keihin BH carburetor?
Yes, this EBC #50 pilot jet is specifically engineered as a direct OEM replacement for Harley-Davidson Big Twin and Sportster models equipped with Keihin BH carburetors.
Do I need to re-jet my carburetor after changing my exhaust?
Modifying your exhaust or intake can change your engine's airflow, often requiring adjustments to your carburetor's jetting, including the pilot jet, to maintain optimal air/fuel mixture. It's advisable to check your tune after such changes.
