ADJUSTING THE DRIVE BELT SLACK

A drive belt that is too tight will cause loud
noises, 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.
TIP
Measure the drive belt slack when the drive
belt is at room temperature, and when the
drive belt is dry.
1. Stand the vehicle on a level surface.
