Mikuni Throttle Valve Slide for Carburetors

The Mikuni throttle valve slide (also called a carburetor slide or throttle slide) is a replacement part for Mikuni carburetors. It controls how much air flows through the carburetor bore as the throttle opens and closes. This regulates the air/fuel mixture and engine response across the rev range.

Key Features:

• Replacement slide for Mikuni carburetors, used in motorcycle, ATV, snowmobile, and other powersports and small-engine applications
• Moves in the carburetor body to meter airflow and set throttle response
• Cutaway height affects the mixture in the low to mid-throttle range, and different slide options allow tuning
• Made to Mikuni's manufacturing standards for a precise fit in the carburetor bore and smooth, consistent movement
• Restores crisp throttle action when the original slide is worn, scored, or sticking

Mikuni has made carburetors for decades and is a long-established name in the powersports world. Choose the correct slide for your carburetor model and tuning needs from the available options on this page. Installing a new slide is a routine carburetor service or tuning job.
