Mikuni Carburetor Jet Needle Jets

Mikuni jet needle jets, also called needle jets or main jet nozzles, are precision-machined carburetor parts. They meter fuel as it flows around the jet needle and into the carburetor venturi. The needle jet works with the jet needle to control the fuel mixture through the mid-range throttle openings. This makes it a key part of carburetor tuning for motorcycles, ATVs, snowmobiles, personal watercraft, and other powersports and small-engine applications.

Key Features:

• Made by Mikuni, a long-established Japanese carburetor manufacturer used on many OEM and aftermarket powersports applications
• Precision-machined brass construction for consistent fuel metering
• Works together with the jet needle and main jet to set mid-range fuel delivery
• Lets you fine-tune air/fuel mixture for changes in altitude, temperature, exhaust, intake, or engine modifications
• Replaces worn needle jets that can cause rich or lean running, poor throttle response, or inconsistent idle-to-midrange performance

Fitting a correct, clean needle jet helps restore carburetor performance and gives you tuning flexibility. Choose the individual part number that matches your carburetor and tuning needs.
