ADJUSTING THE DRIVE CHAIN SLACK

TIP
• Measure the drive chain slack halfway
between the drive axle and the rear axle.
• When checking and adjusting the drive chain
slack, there should be no weight on the vehi-
cle and all tires must be touching the ground.

the engine and other vital parts, and one
that is too loose can skip and damage the
swingarm or cause an accident. Therefore,

fied limits.

• Drive chain slack "a"
