Description
Aqua Sport Keihin Carburetor Adapter for 44mm Mikuni Intake Manifolds is designed to provide a clean, reliable solution for mounting Keihin CDKII carburetors onto popular 44mm Mikuni-style intake manifolds used on personal watercraft engines. This adapter allows riders and builders to integrate proven Keihin carburetion while maintaining proper carb orientation, airflow alignment, and secure mounting for consistent performance.
Compatible with Keihin CDKII 38mm and 42mm carburetors such as the 53-3305 model, this adapter works with both OEM and aftermarket 44mm Mikuni intake manifolds. The design allows the carburetor to stand upright in the engine bay, with only a slight rotational adjustment to provide clearance for the adapter mounting hardware. This positioning helps maintain proper fuel bowl orientation while ensuring adequate clearance and ease of installation.
Precision-machined for accurate fitment, the adapter creates a solid interface between the carburetor and intake manifold, reducing the risk of air leaks that can affect tuning, throttle response, and engine reliability. Built specifically for marine use, it is designed to withstand vibration, heat cycles, and sustained high-RPM operation commonly encountered in watercraft applications.
Whether you are upgrading an existing setup or fine-tuning a performance build, the Aqua Sport Keihin Carburetor Adapter offers dependable fitment and flexibility for riders who prefer Keihin carburetors on Mikuni-based intake systems.
