Mikuni VM38/52-2.5 Throttle Slide Valve Cutaway Carburetors & Accessories - 2.5 38mm

The Mikuni VM38/52-2.5 is a replacement throttle slide valve designed for VM series round slide carburetors. This precision-engineered component features a 2.5 cutaway specification that directly influences throttle response and fuel delivery characteristics in the critical 1/8 to 1/4 throttle range.

Key Features:

• 38mm spigot diameter for VM38 and VM52 carburetor bodies
• 2.5 cutaway size for optimized off-idle performance
• Brass construction with durable chrome plating for corrosion resistance
• Left-hand idle screw position configuration
• Direct OEM replacement for worn or damaged throttle slides

The cutaway specification determines how quickly the needle jet influences fuel metering as the throttle opens. A 2.5 cutaway provides a moderate transition suitable for a wide range of engine configurations. The brass core with chrome plating ensures smooth operation within the carburetor bore while resisting wear and atmospheric corrosion. This throttle slide is compatible with Mikuni VM-series round slide carburetors commonly found on motorcycles, ATVs, and other powersports applications.
