Step-By-Step Installation Guide
Follow these steps to install your new throttle cable on a Harley Davidson. Ensure you have all tools ready and maintain safety throughout.
Removing The Old Throttle Cable
- Disconnect Battery: Always start by disconnecting the negative battery terminal. This prevents electrical shorts during the process.
- Remove Air Cleaner: Take off the air cleaner cover to access the throttle body. Depending on your model, you may need to unscrew it completely.
- Locate Throttle Cable: Identify the throttle cable connected to the throttle grip and throttle body.
- Loosen Cable Adjuster: Unscrew the adjuster located at the throttle body. This eases the removal of the old cable.
- Release Cable Ends: Pull back the throttle grip and carefully remove the cable from both the throttle grip and throttle body. Ensure you’re gentle to avoid damaging surrounding components.
Installing The New Throttle Cable
- Prepare New Cable: Unpack your new throttle cable and confirm that it matches your old cable for proper fit.
- Connect to Throttle Grip: Insert one end of the cable into the throttle grip. Ensure it seats properly and that the throttle moves smoothly.
- Route Cable: Route the cable along the existing path, avoiding any sharp edges or areas that may pinch it.
- Attach to Throttle Body: Connect the cable to the throttle body, ensuring it’s secure and properly aligned.
- Tighten Cable Adjuster: Once hooked up, tighten the cable adjuster at the throttle body to secure the cable.
- Check Slack: Start by twisting the throttle. Ensure there’s minimal slack in the cable. Aim for about 1/8 inch of free play.
- Adjust As Needed: If the cable feels too loose, adjust the tension by turning the adjuster until desired slack is achieved.
- Test Throttle Response: Slowly twist the throttle grip to ensure smooth operation. The throttle should return quickly and without resistance.
- Final Checks: Confirm all connections are secure and are free from tangles or pinches. Reattach the air cleaner cover, then reconnect the battery.
Testing The Installation
Testing the throttle cable installation ensures that everything functions correctly and safely. Follow these steps to confirm proper operation.
Checking The Throttle Response
- Start the Engine: Turn the ignition on and start your Harley. Allow the engine to idle for a minute.
- Twist the Throttle: Gradually twist the throttle grip. The engine should respond smoothly without hesitation or stalling.
- Observe the RPMs: As you adjust the throttle, watch the RPM meter. It should increase and decrease smoothly in response to your movements.
- Return to Idle: Release the throttle and ensure the RPMs return to idle quickly.
- Inspect Cable Connections: Check that both ends of the throttle cable are securely attached. This includes the connection to the throttle grip and the throttle body.
- Examine for Binding: Turn the handlebars fully in each direction. The throttle cable should not bind or restrict movement.
- Verify Slack: Ensure there’s a slight amount of slack in the cable when the throttle is closed. This prevents the throttle from sticking.
- Secure All Fasteners: Make sure that all screws and clamps are tightened to the manufacturer’s specifications to avoid future complications.
