The rear brake light switch is activated by the brake pedal
and is properly adjusted when the brake light comes on
just before braking takes effect. To adjust the rear brake
light switch, hold the switchbody so it does not rotate while
turning the adjusting nut.
Turn the adjusting nut in direction a to make the brake
light come on earlier.
Turn the adjusting nut in direction b to make the brake
light come on later. Checking the front brake pads and rear brake shoes
A wear indicator is provided on each brake. This indicator
allows checking of brake pad/shoe wear without
disassembling the brake.

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 lower level
and replenish when necessary. Observe these precautions:

%"



1. When checking the fluid level, make sure the top of the
master cylinder is level by turning the handlebars.
2. Use only the designated quality brake fluid. Otherwise,
the rubber seals may deteriorate, causing leakage and
poor brake performance.
Recommended brake fluid:
DOT #4
NOTE:
If DOT #4 is not available, #3 can be used.

may result in a harmful reaction and lead to poor brake
performance.
4. Be careful that water does not enter the master cylinder
when refilling. Water will significantly lower the boiling
point of the fluid and may result in vapor lock.
5. Brake fluid may deteriorate painted surfaces or plastic
parts. Always clean up spilled fluid immediately.
6. Have a Yamaha dealer check the cause if the brake
fluid level goes down.1. Complete fluid replacement should be done only by
trained service personnel.
2. Have a Yamaha dealer replace the following
components during periodic maintenance or when they
are damaged or leaking.
a. Replace all rubber seals every two years.
b. Replace all hoses every four years. Brake fluid replacement

NOTE:
Spin the wheel several times and find the tightest position
of the chain. Check and/or adjust the chain slack while it is
in this tightest position.
To check the chain slack the motorcycle must be held
straight up with both wheels on the ground and without rider.
Check the slack at the position shown in the illustration.
Normal slack is approximately 40 ~ 55 mm (1,6 ~ 2,2 in). If
the slack exceeds 55 mm ( 2,2 in), adjust.Drive chain slack check
