Kawasaki 550 SX (1991-1995 reed engine) 44mm Mikuni SBN Complete Carb Setup with intake manifold.
H.S.I. BUILT - Performance SBN 44mm jetted to spec for your application, ready to bolt on! The carb comes pre-setup with primer fittings & tee-handle adjusters already installed! This carb setup will work great paired with a stock to modded engine. If you're heavily modifying your 550sx and wanting ultimate performance, a dual SBN 38mm+ carb setup may be the better route for you!
Are you tired of chasing your tail trying to get your Keihin carburetor running right? Switching to an SBN on that ski is by far the best decision!
What intake option should I select for my 550sx?
-
THIS option: PJS Intake Manifold - Overall the PJS manifold will flow better than the OEM intake and for performance, is the better option to go with. As well as no port matching is needed (bore size is already 44mm)
-
Option 2: Keihin (38mm) to Mikuni Adapter Plate (in another listing here) - A little more cost effective option. IF YOU DO THE ADAPTER PLATE - you will need to get your intake manifold port matched to the 44mm plate/carb.
Primer needed: You will need this to utilize the carb's equipped primer fittings. Add plunger style or bulb style here.
*AIR FILTER IS NOT INCLUDED WITH THIS SETUP - A SHORTY 1.5" IS NEEDED
PLEASE NOTE: Include in the notes section at checkout the elevation where you ride, and if your ski has a stock or aftermarket exhaust. *This carb setup usually takes 4-6 business days to be fit into the service schedule for assembly - we will email you to verify prior to assembling.
