NOTICE
ECA17641
Brake flui d may damag e painted

clean up spille d flui d imme diately.As the brake pads wear, it is normal for
the brake fluid level to gradually go
down. A low brake fluid level may indi-
cate worn brake pads and/or brake
system leakage; therefore, be sure to
check the brake pads for wear and the
brake system for leakage. If the brake fluid level goes down suddenly, have a
Yamaha dealer check the cause before further riding.
EAU22733
Chan gin g the brake flui dHave a Yamaha dealer change the
brake fluid at the intervals specified in
the periodic maintenance and lubrica-
tion 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.

To check the drive belt slack
1. Place the vehicle on the side- stand.
2. Note the current position of the drive belt using the marks near the
drive belt check hole.TIPThe marks near the drive belt check
hole are 5.0 mm (0.2 in) apart.
3. Note the position of the drive beltwith a force of 45 N (4.5 kgf, 10 lbf)
applied to the belt with a belt ten-
sion gauge as shown.TIPA belt tension gauge is available at a
Yamaha dealer.4. Calculate the drive belt slack bysubtracting the measurement not-
ed in step 2 from the measure-
ment noted in step 3. 5. If the drive belt slack is incorrect,
have a Yamaha dealer adjust it.
