H.S.I. Kawi 550SX 44mm Mikuni SBN Carb Setup
H.S.I. Kawasaki 550 SX (1991-1995 reed engine) 44mm Mikuni SBN Complete Carb Setup 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! 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! What intake option should I select for my 550sx? Option 1: 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 - A little more cost effective option. IF YOU DO THE ADAPTER PLATE
