Drive chain slack check

NOTE
Move the ATV back and forth and find the tight-
est position of the drive chain. Check and/or
adjust the chain slack while it is in this tightest
position.
To check the drive chain slack, all tires must be
touching the ground and there should be no
weight on it. Check the drive chain slack at the
position shown in the illustration Normal slack is
approximately 30–40 mm (1.2–1.6 in). If the slack
exceeds 40 mm (1.6 in), adjust it to specification.
