4. Setup and Installation

4.1. Tools Required

• Screwdriver set (Phillips and Flathead)
• Hex key set (Allen wrenches)
• Wrenches (appropriate sizes for cable adjusters and handlebar clamps)
• Grip glue (optional, for secure grip attachment)
• Clean cloth
• Lubricant (cable lubricant)

4.2. Installation Steps

Follow these steps carefully for proper installation:

1. Preparation: Park the motorcycle on a stable surface. Turn off the engine and ensure the ignition is off.
2. Remove Old Grips: Carefully remove the existing throttle grip and housing from the right handlebar. Remove the left handlebar grip. Disconnect the throttle cable(s) from the carburetor/throttle body and the old throttle housing.
3. Clean Handlebar: Thoroughly clean the handlebar surface where the new grips and throttle housing will be installed. Remove any old glue or residue.
4. Install New Throttle Housing: Slide the DOMINO throttle housing onto the right handlebar. Position it correctly and secure it with its mounting screws/clamps, ensuring it does not interfere with other controls (e.g., brake lever). Do not overtighten.
5. Connect Throttle Cable: Route the throttle cable(s) through the new throttle housing. Connect the cable end(s) to the throttle cam inside the housing. Ensure the cable moves freely without binding.
6. Install Left Grip: Slide the matching grip onto the left handlebar. If using grip glue, apply a thin, even layer to the handlebar before sliding the grip on. Allow adequate drying time if glue is used.
7. Adjust Cable Tension: Use the provided cable adjuster (and any adjusters on the cable itself) to set the correct throttle cable tension. There should be a small amount of free play (typically 2-3mm) at the throttle grip before the cable begins to pull.
8. Final Check: Rotate the throttle grip from fully closed to fully open several times. Ensure it returns smoothly and completely to the closed position without sticking. Check that the throttle does not bind when turning the handlebars from lock to lock. Start the engine and verify that the idle speed is stable and the throttle operates correctly.

5. Operating Instructions

The DOMINO Short-Stroke Enduro Throttle Grip Set provides a quicker throttle response due to its reduced rotation angle. Operate the throttle by rotating the right grip towards you to increase engine RPM and away from you to decrease engine RPM. Always operate the throttle smoothly and deliberately, especially when accustomed to a standard throttle setup.

6. Maintenance

Regular maintenance ensures optimal performance and longevity of your throttle grip set.

• Cable Lubrication: Periodically lubricate the throttle cable(s) to ensure smooth operation and prevent corrosion.
• Grip Inspection: Inspect the grips for wear, tears, or looseness. Replace worn grips to maintain proper control.
• Housing Inspection: Check the throttle housing for any cracks, damage, or loose fasteners. Ensure all components are securely attached.
• Cable Adjustment: Regularly check and adjust throttle cable free play. Excessive free play can lead to delayed response, while too little can cause the throttle to stick or the engine to rev unexpectedly.
• Cleaning: Keep the throttle housing and grips clean from dirt and debris. Use a mild cleaner and a soft cloth.
