How should a technician check a motorcycle wheel's spoke tension on a wire-spoked wheel?

1. Tap each spoke with a spoke wrench and listen for a clear, ringing tone of similar pitch
2. Measure the diameter of each spoke using an outside micrometer
3. Wiggle the tire side-to-side while the bike is on the center stand
4. Tighten every spoke as hard as possible with a standard pair of pliers
