MIKUNI HEX MAIN JETS 4/PK #540 - 134-8540

The Mikuni Hex Main Jets #540 are carburetor fuel jets sized at #540 and sold as a 4-pack, making the Mikuni hex main jets #540 4-pack carburetor tuning solution the right call for any rider running the most extreme fuel delivery demands on a radically built Mikuni-carbureted machine. That #540 sizing sits at the absolute ceiling of the Mikuni hex main jet range where only the most aggressive big-bore builds and wild modifications can even put that much fuel to use. Getting your air-fuel ratio locked in at the correct jet size is crisp compared to chasing a stumbling throttle with guesswork. Having four jets on hand means you won't be caught short when you need to step sizes or swap back during a tuning session.

• Fits Mikuni hex-style carburetors for a direct no-fuss installation.
• Keeps your carburetor fuel jetting powersports toolkit stocked with four jets per order.
• Designed for riders who won't accept a rich or lean condition when a jet swap fixes it.
