Introduction
This manual provides essential instructions for the installation, operation, and maintenance of your X-PRO Throttle Lever Thumb Controller Assembly. Designed for 50cc to 200cc ATVs, this component is crucial for controlling engine speed. Please read this manual thoroughly before installation and use to ensure proper function and safety.
Setup and Installation
Proper installation is vital for the safe and effective operation of your ATV. Follow these steps carefully:
- Preparation: Ensure the ATV is turned off and the ignition key is removed. Gather necessary tools, which typically include wrenches and screwdrivers.
- Remove Old Assembly (if applicable): Carefully disconnect the existing throttle cable from the carburetor and remove the old throttle assembly from the handlebars.
- Mounting the New Assembly: Position the X-PRO throttle assembly on the right handlebar. Ensure it is securely clamped and does not interfere with other controls or movement. The clamp should be tightened firmly but not excessively to avoid damage.
- Connecting the Throttle Cable: Route the new throttle cable from the carburetor to the throttle assembly. Insert the cable end into the thumb lever mechanism. Ensure the cable is seated correctly and moves freely without binding.
- Adjustments: Adjust the throttle cable tension to ensure smooth operation of the thumb lever and proper return to the idle position when released. There should be a small amount of free play in the lever before the throttle begins to open.
- Final Check: Before starting the ATV, manually operate the thumb lever several times to confirm smooth movement and full range of motion. Verify that the throttle closes completely when the lever is released.

Operating Instructions
The throttle lever controls the engine's speed. Familiarize yourself with its operation before riding.
- Acceleration: To increase engine speed, gently push the thumb lever forward. The further you push, the more the throttle opens, increasing engine RPM.
- Deceleration: To decrease engine speed, release the thumb lever. The internal spring mechanism will return the lever to its idle position, closing the throttle.
- Smooth Control: Practice smooth and gradual movements with the thumb lever to maintain precise control over your ATV's speed. Avoid abrupt movements, especially at high speeds.
- Safety Check: Always ensure the throttle returns to the idle position freely and completely when released. If it sticks or does not return fully, do not operate the ATV until the issue is resolved.
Maintenance
Regular maintenance ensures the longevity and safe operation of your throttle assembly.
- Inspection: Periodically inspect the throttle assembly and cable for signs of wear, fraying, corrosion, or damage. Check for any loose connections or mounting hardware.
- Cleaning: Keep the throttle assembly clean from dirt, mud, and debris. Use a damp cloth to wipe down the exterior. Avoid using harsh chemicals that could damage the plastic or metal components.
- Lubrication: Apply a suitable cable lubricant to the throttle cable periodically to ensure smooth operation and prevent corrosion. Follow the ATV manufacturer's recommendations for cable lubrication.
- Cable Tension: Regularly check and adjust the throttle cable tension to maintain the recommended amount of free play.

If you encounter issues with your throttle assembly, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
