Is your vintage thumper losing its iconic steady rhythm, dropping in fuel efficiency, or unexpectedly coughing and stalling at traffic lights? Over long periods of riding, heavy engine vibrations can cause your factory air circuit adjustment to drift out of place. Additionally, over-tightening the screw during maintenance can easily blunt its micro-tapered tip, disrupting the precise air-fuel balance your engine requires at low RPMs.

The Carburetor Air Screw for Royal Enfield Bullet 350 Standard (SKU: CASREB35S) is a premium, CNC-machined brass component manufactured exactly to original equipment factory standards. Operating as an adjustable valve within the carburetor's low-speed idle circuit, it accurately controls the volume of atmospheric air mixed into the pilot loop when the throttle slide is resting. Swapping out your worn screw for this fresh, OEM-spec replacement part eliminates flat spots during initial acceleration, stops deceleration backfiring, and restores that smooth, iconic low-end idle.
