MIKUNI HIGH PERFORMANCE SUPER BN CARBURETOR 40MM I-SERIES - 13-5051

The Mikuni High Performance Super BN Carburetor 40mm I-Series (SKU 13-5051) is a high-flow performance carburetor built for riders who need reliable fuel delivery and strong throttle response, making it the go-to Mikuni Super BN 40mm I-Series performance carburetor for serious powersports builds. At $484.95, the Mikuni 13-5051 runs a 40mm bore with an extended throttle shaft design to move air without restriction where it counts. Throttle response feels crisp thanks to a Viton tip needle valve that holds optimum pop-off pressure consistently. That primer-type cold start system skips the butterfly choke entirely so cold weather starts don't fight you.

• Delivers consistent pop-off pressure using a Viton tip needle valve for reliable fuel control.
• Built with an extended throttle shaft so airflow stays unrestricted through the 40mm bore.
• Designed without a butterfly choke so the primer cold start system increases air flow directly.
• Fits I-Series performance carburetor applications where a direct replacement or upgrade is needed.
• Keeps cold start carburetor performance consistent so you're not fighting the engine on first pull.
