NOTICE
As the V-belt wears, adjustment may be
necessary. To ensure proper clutch per-
formance, the V-belt position should be
adjusted by adding a spacer on each ad-
justing bolt when the V-belt position
reaches 1.5 mm (0.06 in) below the edge of
the secondary sheave assembly.
Have a Yamaha dealer make this adjust-
ment.
TIP
Apply the parking brake before replacing the
V-belt.
1. Remove the shroud and the left side cov-
er, and then remove the drive guard.
