KTM Spoked Wheel TUBELESS System LONG-TERM FIX

Introduction

This tutorial outlines a long-term fix for the common issue of leaking tubeless spoked wheels on KTM motorcycles, specifically focusing on the KTM 790 Adventure R. If you're experiencing problems with your KTM's tubeless system, this guide provides clear, actionable steps to help you resolve the leaks effectively.

Step 1: Gather Necessary Materials

Before beginning the repair, ensure you have all the required materials on hand. This will streamline the process and prevent interruptions.

• Tubeless tire sealant
• Tire levers
• Valve stem tool
• Air compressor or tire pump
• Cleaning cloths
• Soapy water solution
• A container for excess sealant

Step 2: Remove the Wheel

To address the tubeless system, you need to remove the wheel from the motorcycle.

1. Place the motorcycle on a stable stand.
2. Loosen the axle nut using the appropriate wrench.
3. Carefully remove the wheel from the bike, ensuring that any connected brake components are not damaged.

Step 3: Inspect the Wheel and Tire

Examine the wheel and tire for any visible damage. Look for the following:

• Cracks or bends in the rim
• Damage to the spokes
• Worn-out tire bead
• Any punctures or sharp objects embedded in the tire

If you find any damage, consider replacing the affected parts before proceeding.

Step 4: Clean the Wheel

A clean surface is crucial for a proper seal.

1. Use a cleaning cloth to remove dirt and debris from the rim and tire bead.
2. Spray the rim with soapy water and wipe it clean to ensure that there are no contaminants that might interfere with the sealant.

Step 5: Add Sealant

Now, it’s time to apply the tubeless tire sealant.

1. Remove the valve stem using the valve stem tool.
2. Pour the recommended amount of sealant into the tire. Typically, this is around 2-4 ounces, but check the sealant's instructions for specific amounts.
3. Reinstall the valve stem, ensuring it is tight to prevent any leaks.

Step 6: Inflate the Tire

Inflate the tire to the manufacturer’s recommended pressure.

1. Use an air compressor or a tire pump to inflate the tire.
2. As the tire inflates, check for any air leaks by applying the soapy water solution around the rim and valve stem. Look for bubbles forming, which indicate a leak.

Step 7: Rotate the Tire

To evenly distribute the sealant, rotate the tire.

1. Spin the wheel slowly for several minutes to allow the sealant to coat the inside of the tire and rim.
2. This will help seal any small punctures or leaks effectively.

Step 8: Reinstall the Wheel

After confirming that there are no leaks, reinstall the wheel on your KTM.

1. Align the wheel with the axle and carefully slide it back into place.
2. Tighten the axle nut to the manufacturer's specifications.
3. Double-check that all components are secure before moving on.

Conclusion

You’ve successfully addressed the tubeless system leak in your KTM spoked wheel. Regular maintenance and checks can help prevent these issues in the future. Remember to monitor your tire pressure and inspect for leaks periodically. If you encounter persistent problems, consider consulting a professional mechanic for further assistance. Happy riding!
