other sources of ignition such as
the pilot lights of water heaters
and clothes dryers.
2. Do not overfill the fuel tank. Stop filling when the fuel reaches the
bottom of the filler tube. Because
fuel expands when it heats up,
heat from the engine or the sun
can cause fuel to spill out of the
fuel tank.
3. Wipe up any spilled fuel immedi- ately. NOTICE: Immediately
wipe off spille d fuel with a clean,
d ry, soft cloth, since fuel may
d eteriorate painte d surfaces or
plastic parts.

TIPAlthough the total number of clicks of a
damping force adjusting mechanism
may not exactly match the above
specifications due to small differences
in production, the actual number of
clicks always represents the entire ad-
justing range. To obtain a precise ad-
justment, it would be advisable to
check the number of clicks of each
damping force adjusting mechanism
and to modify the specifications as
necessary.

Front fork bleedin g
WARNING
EWA10201
Always blee d b oth fork le gs, other-
wise poor han dlin g an d loss of sta-
b ility may result.When riding in extremely rough condi-
tions, the air temperature and pressure
in the front fork will rise. This will in-
crease the spring preload and harden
the front suspension. If this occurs,
bleed the front fork as follows.
1. Lift the front wheel off the ground according to the procedure on
page 7-28.TIPWhen bleeding the front fork, there
should be no weight on the front end of
the vehicle.2. Remove the bleed screws and al-low all of the air to escape from
each fork leg. 3. Install the bleed screws.
4. Lower the front wheel so that it is
on the ground, install the remov-
able sidestand, and then rest the
motorcycle on it.

2. Shift the transmission into the
neutral position.
3. Turn the starter (choke) on and completely close the throttle. (See
page 4-6.)
4. Start the engine by pushing the kickstarter lever down.
5. When the engine is warm, turn the starter (choke) off.TIPThe engine is warm when it responds
quickly to the throttle with the starter
(choke) turned off.NOTICE

Startin g a warm en gineFollow the same procedure as for
starting a cold engine with the excep-
tion that the starter (choke) is not re-
quired when the engine is warm.
Instead, start the engine with the throt-
tle slightly open.TIPIf the engine does not start after sever-
al kicks, try again with the throttle 1/4
to 1/2 open.

Engine break-in
WARNING
EWA10322
Failure to properly maintain the vehi-
cle or performin g maintenance ac-
tivities incorrectly may increase
your risk of injury or death durin g
service or while usin g the vehicle. If
you are not familiar with vehicle ser-
vice, have a Yamaha d ealer perform
service.1. Before starting the engine, fill the fuel tank with a break-in oil-fuel
mixture as follows.
2. Start and warm up the engine. Check the operation of the con-
trols and the engine stop switch.
(See page 4-1.)
3. Operate the motorcycle in the lower gears at moderate throttle
openings for five to eight minutes.
Stop the engine and check the spark plug condition (see page
7-8); it will show a rich condition
during break-in.
4. Allow the engine to cool. Restart the engine and operate the motor-
cycle as in the step above for five
minutes. Then, very briefly shift to
the higher gears and check the
full-throttle response. Stop the en-
gine and check the spark plug.
5. After again allowing the engine to cool, restart and run the motorcy-
cle for five more minutes. Full
throttle and the higher gears may
be used, but sustained full-throttle
operation should be avoided.
Stop the engine and check the
spark plug again.
6. Allow the engine to cool, remove the cylinder head and cylinder,
and inspect the piston and cylin-
der. Remove any high spots on
the piston with #600-grit wet
sandpaper. Clean all components
and carefully reassemble the cyl-
inder head and cylinder.
7. Drain the break-in oil-fuel mixture from the fuel tank and refill with
the specified mix. (See page 4-3.) 8. Start the engine and check the op-
eration of the motorcycle through-
out its entire operating range.
Stop the engine and check the
spark plug condition. Restart the
motorcycle and ride it for about 10
to 15 more minutes. The motorcy-
cle will now be ready to ride nor-
mally.
After the engine break-in period, thor-
oughly check the motorcycle for loose
parts, oil leakage and any other prob-
lems. Be sure to inspect and make ad-
justments thoroughly, especially cable
and drive chain slack and loose
spokes. In addition, check all fittings
and fasteners for looseness, and tight-
en if necessary.
