Common questions
What is the primary function of a pilot jet in a V-twin carburetor?
The pilot jet controls the fuel and air mixture when the throttle is closed and just beginning to open. It's responsible for the engine's idle quality, cold starting, and smooth transition from idle to low-speed cruising.
How do I choose the correct pilot jet size for my Harley or Indian?
The ideal pilot jet size depends on factors like your motorcycle's model, carburetor type, any engine modifications (exhaust, air cleaner, cam), and even altitude. It's best to consult your service manual, a professional tuner, or online resources specific to your bike for recommendations.
Is it possible to damage my engine if I use the wrong pilot jet size?
Running an engine with an incorrect pilot jet size, especially one that's too lean, can lead to poor performance, excessive heat, and potentially long-term engine damage. Always ensure your jetting provides an appropriate air/fuel mixture for safe operation.
