Mikuni Needle Jet Round Slide Carburetor Jets

Mikuni needle jets for round slide carburetors are precision-machined brass components that meter fuel flow in the mid-throttle range. The jet works with the jet needle, and the clearance between them sets the fuel/air mixture as the throttle slide rises. If you need a replacement or tuning needle jet for a Mikuni round slide carb (also called a needle jet or needle valve jet), this product line covers it.

Key Features:

• Precision-machined brass construction for consistent fuel metering
• Designed for Mikuni round slide carburetors
• Controls mid-range mixture together with the jet needle and throttle slide position
• Available in multiple sizes so you can tune for your engine, exhaust, and intake setup
• Useful as a direct replacement for worn or damaged needle jets, or for fine-tuning performance

Mikuni is a long-established Japanese carburetor manufacturer, and its parts are widely used in motorcycles, ATVs, snowmobiles, and other powersports and small-engine equipment. Choose the needle jet size that matches your carburetor model and tuning needs.
