Kawasaki 650cc 44mm Mikuni SBN Complete Carb Setup with adapter plate.
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.
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 model of Kawi 650?
-
Keihin 38mm OEM intake (silver engine / 1991+) - You can choose between this Keihin to Mikuni Adapter Plate (only works with the 38mm intake) OR go with the PJS Intake Manifold for Mikuni SBN (in another listing here). Overall the PJS manifold will flow better than the OEM intake and for performance, is the better option to go with. IF YOU DO THE ADAPTER PLATE: you will need to get your intake manifold port matched to the 44mm plate/carb.
- Keihin 28mm carb (black engine / 1986-1990) - you HAVE to go with the PJS Intake Manifold for Mikuni SBN (in another listing here).
Parts needed & NOT included:
- Primer - You will need this to utilize the carb's equipped primer fittings. Add plunger style or bulb style here
- Air Filter Adapter - You will need the adapter to run an aftermarket air filter. Add the low type adapter or the tall stack cyclone adapter here (filter gasket included with kit already)
-
Air Filter - You will need to use an aftermarket air filter of your choice. Add the ProK filter or the Riva filter here
*AIR FILTER IS NOT INCLUDED WITH THIS SETUP ALTHOUGH PICTURED
PLEASE NOTE: include in the notes section at checkout the model of ski that your 650cc Kawasaki is in, the elevation where you ride, and if it 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.
