This rebuild kit is for one Mikuni BNI46 Jet Ski carburetor.
To positively ID the carb view them in the Mikuni BNI page. On the pump side (the one with the hose ports) the distance between the 4 screws will be 52mm centre to centre on the short side and 58mm on the other.
Genuine Mikuni rebuild kits only come in the factory blister pack with quality and proven components. Remember when on the water you can’t walk home when an inferior copy lets you down.
