Mikuni Jet Needle for Carburetors

The Mikuni jet needle (also called a carburetor needle or metering needle) is a precision-machined tapered needle. It controls fuel flow through the needle jet in slide-type carburetors. As the throttle slide rises, the needle lifts out of the needle jet. This progressively increases the fuel metered to the engine through the midrange of throttle travel.

Key Features:

• Precisely machined taper profile for consistent, repeatable fuel metering
• Made by Mikuni, a long-established Japanese carburetor manufacturer used on motorcycles, ATVs, snowmobiles, personal watercraft and other powersports equipment
• Works with the needle jet to shape mixture from just off idle to near full throttle
• Adjustable clip position (on clip-style needles) lets you fine-tune the mixture richer or leaner
• Suitable as a replacement for a worn or damaged needle, or for tuning after modifications such as intake, exhaust or jetting changes

A worn or bent jet needle can cause rough running, hesitation, poor throttle response and inconsistent fuel mixture. Replacing it restores accurate metering and carburetor performance. Choose the needle that matches your carburetor and tuning needs from the available options.
