Use a tire repair kit specifically designed for motorcycle tires. Follow the kit instructions carefully. For significant damage, replacing the tube is recommended.

Check for punctures by submerging the inflated tube in water or by listening closely for escaping air. Repair or replace the tube if a puncture is found. Also, inspect the tire for any sharp objects that may be causing the puncture.

Ensure the valve stem is properly seated and that the valve core is not blocked. Check your pump for any issues.

Carefully remove the tire and tube. Inspect the tube for pinch marks, and ensure the tire was correctly seated onto the rim during installation. Apply tire mounting lubricant to ease the process and prevent pinching.
