For a more thorough check, proceed as follows:
1. Remove the drive chain from the engine.
2. Suspend the drive chain from a pin or hook with a 13 kg weight attached at the lower
end.
3. Measure across 23 links as shown in the diagram below. If the drive chain is within
limits, the measurement should be no longer than 147.14 mm. Measurements
beyond 147.14 mm indicate that the drive chain must be replaced.
