MIKUNI HIGH PERFORMANCE SUPER BN CARBURETOR 40MM I-SERIES - 13-5052

The Mikuni High Performance Super BN Carburetor 40mm I-Series (SKU 13-5052) is a high-flow performance carburetor built for powersports riders who need consistent fuel delivery and sharp throttle response, making it the go-to Mikuni Super BN 40mm I-Series performance carburetor for serious builds. At $484.95, the Mikuni 13-5052 runs a 40mm bore with an extended throttle shaft design that keeps air moving without restriction where it matters. Throttle response feels crisp thanks to a Viton tip needle valve that holds optimum pop-off pressure lap after lap. That's the kind of reliability you want when the build has to run right the first time.

• Delivers consistent pop-off pressure so fuel control stays reliable across your RPM range.
• Built with an extended throttle shaft so airflow won't get choked through the 40mm bore.
• Designed without a butterfly choke so the cold start carburetor system pulls more air directly.
• Fits I-Series performance carburetor applications needing a direct replacement or upgrade.
• Holds optimum needle valve pressure so your Mikuni Super BN carburetor won't hunt at idle.
