Mikuni Main Hex Jet Jets

Mikuni Main Hex Jets are replacement main jets for Mikuni carburetors. They are also called main jets or carb jets. The main jet controls fuel flow at mid to full throttle, so it plays a large part in power delivery, throttle response and engine performance. Swapping jets lets you tune the carburetor for your engine and riding conditions.

Key Features:

• Hex-head design for easy installation and removal with a standard socket or wrench
• Precision-machined metering orifice for consistent, repeatable fuel flow
• Corrosion-resistant brass construction suited to fuel system use
• Offered in a range of jet sizes so you can fine-tune the air/fuel mixture
• Made by Mikuni, a long-established maker of carburetors and fuel system components for motorcycles, ATVs, snowmobiles, watercraft and other powersports equipment

Use these jets to re-tune a carburetor after changes in altitude, temperature, exhaust or intake modifications, or other engine changes. Choose the jet size that matches your carburetor model and tuning needs.
