Description
Proper pilot jet sizing is fundamental to carburetor tuning—it directly controls fuel delivery at idle and low-throttle conditions, where engine responsiveness and fuel efficiency are established. If your carb is running rich or lean at cruise, a precision pilot jet swap is often the quickest path to dialing in your air-fuel ratio without pulling the entire carb apart. MIKUNI’s Super BN Series pilot jets are manufactured to exacting tolerances in Japan, ensuring consistent performance across your tuning range.
