drive guard removed.
• When installing the new V-belt, make
sure that it is positioned properly. Other-
wise, the V-belt clutch engagement

bile may move unexpectedly when the
engine is started, which could cause an
accident.

formance, the V-belt position should be
adjusted by adding a spacer on each ad-
justing bolt when the V-belt position

the secondary sheave assembly.
Have a Yamaha dealer make this adjust-
ment.
NOTE:
Apply the parking brake before replacing the
V-belt.
