Is your engine struggling with erratic idling, cold-start drops, or unexpected stalling when you pull up to traffic lights? Over prolonged operational cycles, high engine vibrations can cause your factory pilot circuit adjustments to drift out of calibration. Furthermore, heavy-handed tightening during cleaning routines can easily blunt the micro-tapered tip of your factory screw, disrupting the precise air-fuel balance your motor relies on at lower RPMs.

The Carburetor Air Screw for Suzuki Gixxer (SKU: CASSG1) is a premium, precision-machined brass component built exactly to original factory standards. Acting as an adjustable metering valve within the low-speed idle circuit, it regulates the precise volume of air passing through the bypass loop when the throttle slide is completely closed. Installing this fresh, OEM-spec replacement part eliminates flat spots during off-idle acceleration, curbs deceleration popping, and keeps your idle rock-steady.
