H.S.I. Dual SBN 44mm performance carb set-up.
Are you looking for that extra punch of power and more top speed out of your ski? Then we've got you covered with this bolt on ready setup!
These are a great upgrade for a Yamaha 701 or 760cc setup that is already piped, has a high compression head, and/or an MSD enhancer. Jetted to spec and will make your ski RIP if you're ok with your ski sipping a little more gas than the OEM setups. Reliability and added power - what's better then that?
What carb size should I select?
-
44mm - If you are a stock engine and/or with minimal upgrades such as an aftermarket exhaust, high compression head, or a CDI. This is also the most fuel efficient option
-
46mm - If you have porting in the engine, want a little more top end, and/or just want to say you have a 46's with the above setup.
PLEASE NOTE: Include in the notes section at checkout the model of ski your engine is in, what displacement the engine is, the elevation where you ride, what ignition you have, if it has a stock or aftermarket exhaust, stock or A/M head, and If any engine porting. *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.
SUMMER 2026 - CARB SETUPS ARE CURRENTLY TAKING 10-14 BUSINESS DAYS FOR TURN AROUND TIMES TO SHIP
** H.S.I. is not at fault if you run this carb setup on an application that the carbs were not set up for.
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 standard low type or the tall stack cyclone air filter adapter (filter gasket included with kit already)
-
Air Filter - You will need to use an aftermarket air filter of your choice. Add the Riva filters, ProK performance filters or SE stainless performance filters here.
- Intake Manifold - The Yamaha Superjet (62T) manifold will NOT work with these dual carbs. You can upgrade to the DASA, PHP or any aftermarket billet 62t based intake manifold that will flow more air.
