Adjusting Your Motorcycle Clutch: A Step-by-Step Guide

Are you experiencing excessive clutch movement or clutch creep in your motorcycle? It might be time for a clutch adjustment. In this guide, we will walk you through the process of adjusting the clutch on a late model big twin, such as the 2008 Street Glide. Don't worry if you have a different model; the process is similar for all late model big twins. We'll cover everything from the tools you'll need to the step-by-step instructions for making the adjustment. So, let's get started!

Introduction

One of the crucial components of any motorcycle is the clutch. Over time, the clutch may start to wear out, resulting in excessive movement or clutch creep. These issues can be resolved through a simple clutch adjustment. By following the steps outlined in this guide, you'll be able to fine-tune your clutch and ensure smooth operation.

Tools Needed for Clutch Adjustment

Before we dive into the adjustment process, let's gather the tools you'll need:

• T27 Torx with a quarter-inch ratchet
• 11/16 wrench
• 9/16 wrench
• Half-inch wrench
• 7/32nd Allen wrench
• Torque wrench

Make sure you have all these tools ready before you begin.

Removing the Derby Cover

To start the clutch adjustment, we need to gain access to the clutch. Follow these steps to remove the derby cover:

1. Locate the five Torx head screws on the derby cover.
2. Use the T27 Torx with a quarter-inch ratchet to remove the screws.
3. Take off the derby cover and set it aside.

Now, we have access to the clutch and can proceed with the adjustment.

Loosening the Clutch Cable Adjuster

Next, we'll focus on the clutch cable adjuster. This step involves loosening the adjuster to create free play in the clutch lever. Here's how you do it:

1. Pull down the rubber boot covering the clutch cable adjuster.
2. Using a half-inch wrench, grip the adjuster portion of the cable.
3. Use a 9/16 wrench to loosen the lock nut on the adjuster.
4. Roll the lock nut up to create slack in the cable.
5. Crank the adjuster counterclockwise to add free play to the clutch lever.

Now that we have added free play to the clutch lever, we can proceed to adjust the clutch itself.

Adjusting the Clutch

To adjust the clutch, follow these steps:

1. Take an Allen wrench and hold the adjuster screw.
2. Use an 11/16 wrench to loosen the lock nut.
3. Carefully back off the adjustment screw until you feel it touch.
4. Once you feel the touch, back it off a half to a full turn, depending on the desired adjustment.
5. Remember, it's essential to have a light touch when making adjustments.

With the clutch adjustment made, let's move back up to the clutch cable adjuster to remove any slack from the clutch lever.

Tightening the Clutch Cable Adjuster

To remove the slack from the clutch lever, follow these steps:

1. Run the adjuster nut (the long one) back down.
2. As you tighten the nut, it will take up the slack in the cable and tighten the lever.
3. Keep in mind that you need about an eighth of an inch of play in the lever.
4. Adjust the nut until you achieve the desired amount of play.

Once you're satisfied with the adjustment, tighten the lock nut to secure the clutch cable adjuster.

Reinstalling the Derby Cover

Now that the adjustment is completed, it's time to put everything back together. Here's how you reinstall the derby cover:

1. Check the gasket on the derby cover for any damage.
2. If the gasket is in good shape, reuse it; otherwise, replace it.
3. Place the derby cover back on the primary cover.
4. Insert the Torx head screws and tighten them using the T27 Torx with a quarter-inch ratchet.
5. Torque the screws to approximately 10 Newton meters or 85-inch pounds.

Checking for Proper Adjustment

Before you take your bike out for a ride, it's important to verify that the clutch adjustment is correct. Here's what you should check for:

• Smooth clutch engagement
• No excessive clutch movement
• No clutch creep
• Approximately an eighth of an inch of play in the clutch lever

Reasons for Clutch Adjustment

There are two primary reasons why you might need to adjust your motorcycle clutch: wear and clutch creep. Here's a closer look at these reasons:

1. Wear: Over time, a clutch can wear, resulting in excessive movement in the lever. If you notice increased play or difficulty engaging the clutch, it's a strong indication that an adjustment is needed.

2. Clutch Creep: Clutch creep refers to the clutch trying to engage even when fully pulled in. This issue can be caused by stretched cables or worn clutches. Adjusting the clutch can help resolve clutch creep and ensure optimal performance.

Conclusion

Performing a clutch adjustment is a straightforward process that can help maintain the performance of your motorcycle's clutch. By following the step-by-step guide outlined in this article, you'll be able to fine-tune your clutch and address any issues related to excessive movement or clutch creep.
