MIKUNI HEX MAIN JETS 4/PK #290 - 134-8290

The Mikuni Hex Main Jets #290 are carburetor fuel jets sized at #290 and sold as a 4-pack, making the Mikuni hex main jets #290 4-pack carburetor tuning solution the right pick for any rider pushing a seriously built Mikuni-carbureted machine that demands maximum fuel flow. That #290 sizing is deep into large-jet territory, suited for high-displacement builds or heavily modified engines where standard jets simply won't flow enough fuel to keep up. Getting your air-fuel ratio sharp at the correct jet size is crisp compared to chasing a bog or flat spot with guesswork. Buying four jets at once means you won't be stuck mid-tune when you need to step up or down a size.

• Delivers consistent fuel flow at the #290 jet size for repeatable tuning results.
• Built to Mikuni hex main jet spec so flow rates match factory carburetor standards.
• 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.
