A drive belt that is too tight will overload the engine and other vital parts, and one that is too loose can skip and damage the swingarm or cause an accident. Therefore, keep the drive belt slack within the specified limits.
Measure the drive belt slack when the engine is cold, and when the drive belt is dry.
