Mikuni Keihin Main Jet Size Nickel Plated

The Mikuni Keihin nickel plated main jet is a carburetor metering jet. It controls how much fuel flows through the main circuit at mid to wide-open throttle. Use it to tune air/fuel mixture after changing the intake, exhaust, or engine, or when you ride at a different altitude or in different weather. It is also called a main fuel jet or carb jet.

Key Features:

• Precision-machined brass body with a nickel-plated finish for corrosion resistance and durability
• Accurately calibrated orifice for consistent, repeatable fuel metering
• Available in a range of jet sizes so you can fine-tune jetting for your setup
• Replaces worn, damaged, or clogged main jets to restore proper carburetor performance
• Easy installation. The jet threads into the carburetor's main jet holder or needle jet assembly

Mikuni and Keihin are respected names in carburetor design. Their jets are widely used in motorcycle, ATV, snowmobile, and other powersports applications. Choose the correct size for your carburetor, and check your jetting after installation by reading the spark plug.
