The jet needle's taper determines the amount of fuel delivered during mid-range operation. As the throttle opens and the needle rises out of the needle jet, the changing diameter controls fuel flow—a thinner diameter allows more fuel, while a thicker diameter restricts flow. This precise control is essential for optimal engine performance and throttle response in the quarter to three-quarter throttle range.

Mikuni jet needles are manufactured to exacting standards to ensure consistent performance and reliability. This genuine replacement part ensures proper carburetor function and maintains the fuel delivery characteristics your engine was designed for.
