Mikuni Throttle Slide Cutaway for VM Series Carburetors

The Mikuni throttle slide (also called a throttle valve or carb slide) is a genuine replacement part for Mikuni VM Series round slide carburetors. The slide moves up and down in the carburetor bore. It controls airflow and works with the needle and needle jet to meter fuel as the throttle opens.

Key Features:

• Genuine Mikuni replacement slide for spigot-mount VM Series carburetors
• Cutaway on the engine side of the slide changes the air-fuel mixture in the low-to-mid throttle range, roughly 1/8 to 1/2 throttle
• Available in a range of cutaway numbers, so you can lean or richen the mixture to suit jetting, modifications and tuning needs
• Machined with guide pin slot and idle groove details that match the carburetor it is made for
• Durable metal construction built for smooth, consistent movement in the carburetor bore

Use a replacement slide to restore a worn carburetor, or to fine-tune throttle response and mid-range mixture. A smaller cutaway number gives a richer mixture just off idle. A larger number gives a leaner mixture. Choose the slide series that matches your carburetor's spigot size, idle screw side and guide pin slot width. Mikuni has a long record of precision carburetor manufacturing for motorcycles, ATVs and other powersports engines.
