Frequently Asked Questions

What does a mixture screw do?

The mixture screw adjusts the fuel-air ratio at idle and low-throttle RPMs. Turning it in or out fine-tunes smooth idle quality and off-idle response.

Will this fit my carb?

This part is designed for butterfly-style carburetors on V-twin engines. Verify your carb type before ordering — it won't fit Keihin or other non-butterfly designs.

Is installation difficult?

Simple adjustment. Screw it in gently until it seats, then back out 1-2 turns as a starting point and fine-tune by ear at idle.

What's included?

The mixture screw only — no springs, gaskets, or additional hardware.
