Honda Shadow Dice Idle Screw

Ditch the boring stock knob and give your dual‑carb Shadow a functional detail upgrade with the Honda Shadow Dice Idle Screw—easy to grab, easy to tune, and built to get noticed on every fuel stop.

Features:

• Dice‑style idle screw head that adds attitude right where you actually wrench and ride.
• Designed for quick, tool‑free idle adjustments on dual‑carb Honda Shadows.
• Machined for a positive grip so you can tweak your idle even with gloves on.
• Clean stainless look that plays well with polished, raw, or blacked‑out builds.

Fitment & Compatibility:

• Fits dual‑carb Honda Shadow 600 and 750 carburetors.
• Works with any setup using a 4 mm idle adjustment screw style similar to the OEM Shadow dual‑carb design.
• May require trimming the screw length to clear cooling fins on Shadow 600 models; test‑fit before final install.

Construction & Hardware:

• All stainless steel hardware for corrosion resistance and long‑term use in real‑world riding conditions.
• Built to handle repeated adjustments without rounding, stripping, or seizing.
• Small part, big visual impact—especially when paired with other Gattis Garage Shadow carb and intake upgrades.

Install Notes:

1. Remove your stock idle screw and thread in the Dice Idle Screw using existing carb threads.
2. Set idle with the engine fully warmed up for the most accurate adjustment.
3. On Shadow 600 models, mock up the screw, mark where it touches the fins, and carefully trim to length before final install.
