PERIODIC MAINTENANCE AND MINOR REPAIR
reservoir is level.
●
Use only the recommended quality
brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking
performance.
Recommended brake fluid:
DOT 4
●
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and lead
to poor braking performance.
●
Be careful that water does not enter
the brake fluid reservoir when
refilling. Water will significantly lower
the boiling point of the fluid and may
result in vapor lock.
●
Brake fluid may deteriorate painted
surfaces or plastic parts. Always
clean up spilled fluid immediately.
●
As the brake pads wear, it is nor-
mal for the brake fluid level to
gradually go down. However, if the
brake fluid level goes down
suddenly, have a Yamaha dealer
check the cause.
Changing the brake fluid
Have a Yamaha dealer change the brake
fluid at the intervals specified in the
NOTE after the periodic maintenance
and lubrication chart. In addition, have
the oil seals of the master cylinders and
calipers as well as the brake hoses
replaced at the intervals listed below or
whenever they are damaged or leaking.
●
Oil seals: Replace every two years.
●
Brake hoses: Replace every four
years.
Drive chain slack
The drive chain slack should be checked
before each ride and adjusted if
necessary.
To check the drive chain slack
1. Place the motorcycle on a level
surface and hold it in an upright
position.
When checking and adjusting the drive
chain slack, the motorcycle should be
positioned straight up and there should
be no weight on it.
2. Shift the transmission into the
neutral position.
3. Move the rear wheel by pushing the
motorcycle to locate the tightest
portion of the drive chain, and then
measure the drive chain slack as
shown.
Drive chain slack:
45 ~ 60 mm (1.77 ~ 2.36 in)
