N. ADJUSTING THE DRIVE CHAIN
SLACK
The drive chain slack must be checked at
the tightest point on the chain.
A drive chain that is too tight will over-
load the engine and other vital parts,
and one that is too loose can skip and
damage the swingarm or cause an acci-
dent. Therefore, keep the drive chain
slack within the specified limits.
1. Stand the vehicle on a level surface.
Securely support the vehicle so that
there is no danger of it falling over.
Both wheels should be on the ground with-
out a rider on the vehicle.
2. Rotate the rear wheel several times
and check the drive chain to locate its
tightest point.
3. Measure:
• drive chain slack (a)
Out of specification → Adjust.

b. Turn both adjusting bolts (3) in direc-
tion (a) or (b) until the specified drive
chain slack is obtained.
