• Container: A small container collects the old fluid.

Step-by-Step Bleeding Process

1. Locate the Bleed Screw: Find the bleed screw near the clutch master cylinder. It’s usually a small, brass screw on the cylinder body.
2. Attach the Siphon Hose: Slip one end of the siphon hose onto the bleed screw. Place the other end in your collection container.
3. Open the Bleed Screw: Use the wrench to turn the bleed screw counterclockwise. Open it about a quarter turn to start the flow of fluid.
4. Pull the Clutch Lever: Squeeze the clutch lever slowly and hold it. This action pushes fluid through the system.
5. Watch for Bubbles: Observe the fluid in the siphon hose. Look for air bubbles, which indicate trapped air in the system.
6. Close the Bleed Screw: While still holding the clutch lever, turn the bleed screw clockwise until it’s tight. This step prevents air from entering when you release the lever.
7. Release the Clutch Lever: After securing the bleed screw, slowly release the clutch lever.
8. Repeat: Repeat steps 3 to 7 until no air bubbles appear in the fluid. This process may take multiple tries.
9. Check Fluid Level: After bleeding, check the fluid level in the master cylinder reservoir. Fill it to the recommended level if necessary.

Final Checks

Perform a test ride to ensure the clutch operates smoothly. If issues persist, seek assistance from a qualified mechanic for a thorough inspection. Maintaining your clutch system enhances your Yamaha VMAX’s overall performance and longevity.
