DRIVE V-BELT
When installing the new V-belt, make sure
that it is positioned within the specified dis-
tances
1 from the edge of the secondary
sheave.
If not, the clutch engagement speed will be
changed. The machine may move unexpect-
edly when the engine is started.
Adjust the V-belt position by removing or
adding a spacer
2 on each adjusting bolt.
For this adjustment, consult a Yamaha deal-
er or another qualified mechanic.
As the V-belt wears, adjustment may be
necessary. To ensure proper clutch perfor-
mance, the V-belt position should be ad-
justed by adding a spacer on each adjusting
bolt when the V-belt position reaches below
the edge.
For this adjustment, consult a Yamaha deal-
er or another qualified mechanic.
