Mikuni VM3411020 VM34/110-2.0 Throttle Slide - 2.0 Cutaway, Brass, Left-Hand Idle

The Mikuni VM3411020 is a genuine OEM-specification throttle valve slide for Mikuni VM-series round slide carburetors. Featuring a 2.0 cutaway size (part designation VM34/110-2.0), this slide is designed for use with VM30, VM32, and VM34 spigot-mounted carburetors and delivers precise fuel-air mixture control in the critical 1/8 to 1/2 throttle range.

Constructed from chrome-plated brass for durability and corrosion resistance, this throttle valve is configured with a left-hand (LH) idle screw position, making it compatible with carburetors that use a left-side idle adjuster. The slide uses the standard keyhole cable attachment method, where a round metal disc under the spring retains the throttle cable securely within the slide.

The cutaway number on a Mikuni round slide carburetor directly influences mixture from idle through mid-throttle — a smaller cutaway number like 2.0 results in a richer mixture, while larger numbers lean the mixture. Always verify your carburetor's idle screw position and body style before ordering, as throttle slides vary in design across carburetor configurations. Refer to Mikuni manual MM36 for proper application guidance.
