Yamaha Aerox Top Speed Serye | Center & Clutch Spring | Ep13

Introduction

This tutorial will guide you through enhancing the top speed of a Yamaha Aerox by focusing on modifications to the center and clutch spring. These adjustments can significantly impact performance, making it a valuable skill for anyone looking to optimize their ride.

Step 1: Understanding the Importance of Springs

Before diving into the modifications, it's essential to understand how the center and clutch springs affect your scooter's performance.

• Center Spring: This spring influences the variator's operation, affecting acceleration and top speed. A stiffer spring can improve speed but may reduce acceleration.
• Clutch Spring: This spring controls when the clutch engages. A stiffer clutch spring will delay engagement, allowing for higher torque at lower speeds.

Practical Tip

Choose springs that match your riding style. If you prefer quick acceleration, consider softer springs; for top speed, go stiffer.

Step 2: Gathering Necessary Tools and Parts

Prepare your workspace with the following tools and components:

• Tools:

  • Socket wrench set
  • Screwdriver set
  • Torque wrench
  • Pliers
  • Safety goggles

• Parts:

  • Upgraded center spring
  • Upgraded clutch spring
  • Variator weights (optional for additional tuning)

Common Pitfall

Ensure your scooter is off and completely cooled down before starting any modifications to avoid injury.

Step 3: Disassembling the Scooter

To access the springs, you need to disassemble certain parts of the scooter:

1. Remove the seat and side panels to access the underseat compartment.
2. Unscrew the variator cover using a socket wrench.
3. Take out the variator carefully to avoid damaging any components.

Step 4: Replacing the Center Spring

Once you have access to the variator:

1. Remove the old center spring from the variator.
2. Install the new center spring by aligning it properly within the variator assembly.
3. Reassemble the variator, ensuring all parts fit snugly.

Practical Tip

Apply a small amount of grease to the spring to reduce wear over time.

Step 5: Replacing the Clutch Spring

Next, focus on the clutch spring:

1. Remove the clutch assembly by unscrewing it from the engine.
2. Take out the old clutch spring from the clutch assembly.
3. Insert the new clutch spring, making sure it is seated correctly.
4. Reassemble the clutch assembly, ensuring it is securely fastened.

Step 6: Reassembling the Scooter

After replacing the springs, it's time to put everything back together:

1. Reinstall the variator cover and secure it with screws.
2. Reattach the side panels and seat.
3. Double-check all connections to ensure nothing is loose.

Common Pitfall

Avoid over-tightening screws, as this can strip the threads and cause future problems.

Conclusion

By following these steps, you can enhance your Yamaha Aerox's performance by modifying the center and clutch springs. Remember to test your scooter in a safe area after the modifications to see how the changes affect speed and acceleration. Happy riding, and consider exploring further tuning options like variator weights for even more performance enhancements!
