Description
The Watcon Keihin to Mikuni Intake Manifold Adapter is designed for riders who want the flexibility of running modern Mikuni SBN44 or 46 mm carburetors on an existing Keihin intake manifold without a complete intake swap. This precision machined intake adapter helps bridge the gap between older intake designs and newer high performance carburetors, making it ideal for performance builds or fresh upgrades where throttle response and fuel delivery are critical.
- Allows a Mikuni SBN44 or 46 mm carb to bolt onto a Keihin intake manifold while maintaining proper alignment and sealing.
- Machined for a tight, accurate fit to reduce air leaks and maintain consistent fuel atomization under hard acceleration.
- Perfect for riders upgrading to newer style SBN carbs to improve throttle response, tuning range, and overall reliability.
- Requires port matching of the intake manifold to the larger carb bore to prevent airflow restriction and to take full advantage of the adapter.
- Ideal for performance engine builds where every bit of flow and velocity matters, especially on modified stand up and small hull skis.
- Durable construction stands up to harsh personal watercraft environments including vibration, fuel exposure, and heat cycling.
- Simple bolt on installation when paired with proper gaskets and hardware, making it a clean solution for garage builders and pros alike.
For best results, carefully port match the intake manifold to the new larger carb size and verify clearance and throttle operation before riding. Part number # ADPT-K.
