Description
The Watcon Intake Manifold Spacer for Kawasaki JS440/550 is designed to make modern carb conversions clean and reliable on classic piston port motors. When used with a stock 44 mm intake, this spacer lets you run a newer SBN style carburetor on your Kawasaki 440 or 550 engine, providing the critical spacing needed for the fuel pump section and linkage clearance.
- Engineered specifically for Kawasaki JS440 and JS550 piston port engines that are being upgraded to newer SBN style carbs.
- Works with the stock 44 mm intake manifold to position the carb correctly for both airflow and fuel pump body clearance.
- Provides the extra stand off distance needed so the built in fuel pump on the SBN carb does not interfere with the engine or intake casting.
- Helps improve tuning flexibility by allowing the use of modern SBN carbs known for better throttle response and consistent fuel metering.
- Machined for a precise fit to maintain good intake sealing and proper alignment between carb and intake passage.
- Ideal for performance oriented 440 and 550 builds that want updated fueling without changing to a completely different intake system.
- Mounting hardware is sold separately; use matching long stainless hardware kit, part # K550-SPCR-HARDWARE, for correct bolt length and durability.
This intake spacer is a key component when converting a piston port Kawasaki 440 or 550 to a newer SBN version carb, ensuring correct spacing and reliable performance.
