Measuring The Tire Pressure; Checking The Coolant Level; Adjusting The Throttle Cable Free Play - Yamaha WR250FR Assembly Manual

EAA01009
C. MEASURING THE TIRE PRES-
SURE
1. Measure:
Dtire pressure
Out of specification>Adjust.
NOTE:
D Check the tire while it is cold.
D Loose bead stoppers allow the tire to
slip off its position on the rim when the
tire pressure is low.
D A tilted tire valve stem indicates that
the tire slips off its position on the rim.
D If the tire valve stem is found tilted, the
tire is considered to be slipping off its
position.

D. CHECKING THE COOLANT
LEVEL
1. Stand the machine on a level surface.
NOTE:
Make sure that the machine is upright
2. Check:
Dcoolant level
The coolant level should be between
the maximum level mark (a) and mini-
mum level mark (b).
Below the minimum level mark>Add
the recommended coolant to the prop-
er level.

E. ADJUSTING THE THROTTLE
CABLE FREE PLAY
NOTE:
Prior to adjusting throttle cable free play,
the engine idling speed should be adjust-
ed.
1. Measure:
Dthrottle cable free play (a)
Out of specification>Adjust.
Throttle cable free play
(at the flange of the throttle grip):
3 ~ 5 mm (0.12 ~ 0.20 in)
2. Adjust:
Dthrottle cable free play

Basic weight:
With oil,coolant and full fuel tank
122.1 kg (269 lb)
Cold tire pressure:
Front 100 kPa (1.0 kgf/cm 2 , 15 psi)
Rear 100 kPa (1.0 kgf/cm 2 , 15 psi)
CAUTION:
D D Adding water instead of coolant
lowers the antifreeze content of the
coolant. If water is used instead of
coolant, check and correct the
antifreeze concentration
coolant.
D D Use only distilled water. Soft water
may be used if distilled water is not
available.
3. Start the engine, warm it up for several
minutes, and then turn it off.
4. Check:
Dcoolant level
NOTE:
Before checking the coolant level, wait a
few minutes until it settles.
a. Slide back the rubber cover.
b. Loosen the locknut (1).
c. Turn the adjusting nut (2) in direction
(a) or (b) until the specified throttle
cable free play is obtained.
Direction (a):
Throttle cable free play is
increased.
Direction (b):
Throttle cable free play is
decreased.
d. Tighten the locknut.
W
After adjusting the throttle cable free
play, start the engine and turn the han-
dlebar to the right and to the left to
ensure that this does not cause the
engine idling speed to change.
