How to Patch a Motorcycle Inner Tube
- 1). Fill a tub or sink with water. Inflate the inner tube with air from an air pump or compressor. Place the tube into the sink and watch for bubbles. Mark the area where the bubbles are forming with a crayon or a marker.
- 2). Dry the outside of the tube with a towel. Let the air out of the tube by applying pressure to the valve stem core with a small screwdriver.
- 3). Roughen the area of the leak with sandpaper or with the tool included in the repair kit.
- 4). Apply rubber cement to the roughened area and allow to sit for approximately one minute. Press a tube patch over the area and apply pressure.
- 5). Allow the patch to cure overnight, if possible.
