Description
The Watercraft Werks billet aluminum single intake manifold for the Kawasaki JS550 is built for riders who want a clean, direct-fit solution for the Mikuni SBN series of performance carburetors. Unlike many conversion setups that require spacer adapters or stacked plates, this manifold is machined specifically to accept SBN carbs without any spacer adapter, reducing complexity and potential leak points. It is a high-quality upgrade that pairs modern carburetor performance with a strong, reliable mounting platform.
- Direct-fit billet intake manifold for Kawasaki JS 550 engines using Mikuni SBN series carburetors.
- No spacer adapter required, simplifying installation and helping maintain proper alignment between carb and intake tract.
- Includes gaskets and mounting hardware so you have the essential pieces needed for a complete installation.
- Machined from solid aluminum material for superior strength and durability compared to aging cast or modified OEM manifolds.
- Produced on an American-made HAAS CNC machine equipped with a 5-axis trunnion for precise, repeatable machining quality.
- Smooth, carefully designed internal passages support consistent airflow and fuel delivery for performance-oriented builds.
- Styled and finished to look like a true piece of artwork in the engine bay, enhancing the overall appearance of your JS 550.
If you are upgrading your Kawasaki JS550 with an SBN carb, this manifold provides a solid foundation that is designed for the task rather than adapted from something else. The billet construction and tight machining tolerances help reduce the chances of warping, air leaks, or hardware issues that can rob your ski of performance. With gaskets and hardware included, this is an attractive, functional choice for riders building a reliable, responsive JS550 engine package.
