Mikuni VM3411015 VM34/110 Throttle Slide 1.5 Cutaway Brass Chrome Left-Hand Idle

The Mikuni VM3411015 is a genuine Mikuni throttle valve slide designed for VM34/110 series round-slide carburetors. Constructed from brass with a chrome-plated finish for durability and smooth operation, this slide features a left-hand (LH) idle screw position and a 1.5 cutaway size, making it one of the richer-tuning options in the VM34/110 slide lineup.

The throttle valve directly influences the air-fuel mixture ratio between approximately 1/8 and 1/2 throttle, with the greatest impact felt around 1/4 throttle. A smaller cutaway number like 1.5 creates a stronger vacuum signal through the carburetor bore, resulting in a richer fuel mixture in that throttle range — ideal for engines requiring additional fuel delivery at low-to-mid throttle openings.
