4-PRE-OPERATION CHECKSOwners are personally responsible for their vehicle’s condition. Your motorcycle’s vital functions can start to deteriorate
quickly and unexpectedly, even if it remains unused (for instance, if it is exposed to the elements). Any damage, fluid leak or
loss of tire pressure could have serious consequences. Therefore, it is very important that, in addition to a thorough visual in-
spection, you check the following points before each ride.

Inspecting the brake fluid
levelInsufficient brake fluid may let air enter
the brake system, possibly causing the
brakes to become ineffective.
Before riding, check that the brake fluid
is above the minimum level and replen-
ish when necessary.
Observe these precautions:l
When checking the fluid level,
make sure the top of the master
cylinder is level by turning the han-
dlebars.
l
Use only the designated quality
brake fluid. Otherwise, the rubber
seals may deteriorate, causing
leakage and poor brake perfor-
mance.
l
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor brake performance.
l
Be careful that water does not en-
ter the master cylinder when refill-
ing. Water will significantly lower
the boiling point of the fluid and
may result in vapor lock.
l
Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled fluid
immediately.
l
Have a Yamaha dealer check the
cause if the brake fluid level goes
down.

Brake fluid replacementThe brake fluid should be replaced only
by trained Yamaha service personnel.
Have the Yamaha dealer replace the
following components during periodic
maintenance or when they are dam-
aged or leaking:l
oil seals (every two years)

Drive belt slack check1. Put the motorcycle on the side-
stand and make sure that both
wheels are on the ground.
2. Using the reference marks at the
side of the check window, which is
located at the rear left side of the
motorcycle, note the current posi-
tion of the drive belt.3. Apply a force of 45 N (4.5 kg) with
the belt tension gauge to the lower
drive belt run as shown and re-
check the drive belt position in the
check window. The normal drive
belt slack (i.e., the distance be-
tween the original belt position and
its position with the force applied)
is approximately 7.5 ~ 13 mm.
4. If the measured slack exceeds
13 mm, adjust the drive belt.
NOTE:@ The reference marks at the side of the
drive belt check window are 5 mm
apart. @
