Description
Fine-tuning your carburetor’s mid-range fuel delivery is critical for consistent throttle response and overall drivability. The MIKUNI Jet Needle J8-6EJ12-56 gives you precise control over the fuel mixture during the transition zone where most real-world driving happens. If your engine is running rich or lean in the mid-range, swapping to the correct needle specification can eliminate flat spots and optimize power delivery across your RPM band.
