NOTE:
Pre-operation checks should be made each time the motorcycle is used. Such an inspection can be accomplished in a
very short time; and the added safety it assures is more than worth the time involved.wIf any item in the Pre-Operation Check is not working properly, have it inspected and repaired before operating
the motorcycle.

Before riding this motorcycle,
become thoroughly familiar
with all operating controls and
their functions. Consult a
Yamaha dealer regarding any
control or function that you do
not thoroughly understand.
8 8
Never start your engine or let
it run for any length of time in
a closed area. The exhaust
fumes are poisonous and can
cause loss of consciousness
and death within a short time.
Always operate your motorcy-
cle in an area with adequate
ventilation.
8 8
Before starting out, always be
sure the sidestand is up.
Failure to retract the sidestand
completely can result in a seri-
ous accident when you try to
turn a corner.
EAU01177
Starting the engineNOTE:
This motorcycle is equipped with an
ignition circuit cut-off system. The
engine can be started only under one
of the following conditions:
8The transmission is in neutral.
8The sidestand is up, the trans-
mission is in gear and the clutch
is disengaged.
The motorcycle must not be ridden
when the sidestand is down.
EW000056
wBefore going through the following
steps, check the function of the
sidestand switch. (Refer to page

accelerate hard with a cold engine!7.After the engine is warm, turn off
the starter (choke) completely.NOTE:
The engine is warm when it responds
normally to the throttle with the starter
(choke) turned off.

ShiftingThe transmission lets you control the
amount of power you have available
at a given speed for starting, acceler-
ating, climbing hills, etc. The use of
the shift pedal is shown in the illustra-
tion.
To shift into neutral, depress the shift
pedal repeatedly until it reaches the
end of its travel, then raise the pedal
slightly.
EC000048

Do not coast for long periods
with the engine off, and do not
tow the motorcycle a long dis-
tance. Even with gears in neu-
tral, the transmission is only
properly lubricated when the
engine is running. Inadequate
lubrication may damage the
transmission.
8 8
Always use the clutch when
changing gears. The engine,
transmission, and driveline are
not designed to withstand the
shock of forced shifting and
can be damaged by shifting
without using the clutch.

Tips for reducing fuel
consumptionYour motorcycleÕs fuel consumption
depends to a large extent on your rid-
ing style. The following tips can help
reduce fuel consumption:
8Warm up the engine before rid-
ing.
8Turn off the starter (choke) as
soon as possible.
8Shift up swiftly and avoid high
engine speeds during accelera-
tion.
8Do not double-clutch or rev the
engine while shifting down and
avoid high engine speeds with
no load on the engine.
8Turn off the engine instead of let-
ting it idle for an extended length
of time, i.e. in traffic jams, at traf-
fic lights or railroad crossings.
EAU00436
Engine break-inThere is never a more important peri-
od in the life of your motorcycle than
the period between zero and 1,000
km. For this reason we ask that you
carefully read the following material.
Because the engine is brand new,
you must not put an excessive load
on it for the first 1,000 km. The vari-
ous parts in the engine wear and pol-
ish themselves to the correct operat-
ing clearances. During this period,
prolonged full throttle operation, or
any condition which might result in
excessive heating of the engine,
must be avoided.
EAU00453
0 ~ 500 km
Avoid operation above 6,000 r/min.
Stop the engine and let it cool for 5 to
10 minutes after every hour of opera-
tion. Vary the speed of the motorcy-
cle from time to time. Do not operate
it at one set throttle position.
500 ~ 1,000 km
Avoid prolonged operation above
7,000 r/min. Rev the motorcycle
freely through the gears, but do not
use full throttle at any time.
EC000060
cCAfter 1,000 km of operation, be
sure to replace the transmission
oil.
3MB-9-E7 12/27/00 2:52 PM Page 35

1,000 km and beyondFull throttle can be used.

If any engine trouble should
occur during the break-in peri-
od, consult a Yamaha dealer
immediately.

ParkingWhen parking the motorcycle, stop
the engine and remove the ignition
key. Turn the fuel cock to ÒOFFÓ
whenever stopping the engine.
EW000058
wThe exhaust system is hot. Park
the motorcycle in a place where
pedestrians or children are not
likely to touch the motorcycle. Do
not park the motorcycle on a slope
or soft ground; the motorcycle
may overturn.

Periodic inspection, adjustment and
lubrication will keep your motorcycle
in the safest and most efficient condi-
tion possible. Safety is an obligation
of the motorcycle owner. The mainte-
nance and lubrication schedule chart
should be considered strictly as a
guide to general maintenance and
lubrication intervals.
YOU MUST TAKE INTO CONSIDER-
ATION THAT WEATHER, TERRAIN,
GEOGRAPHICAL LOCATIONS, AND
A VARIETY OF INDIVIDUAL USES
ALL TEND TO DEMAND THAT
EACH OWNER ALTER THIS TIME
SCHEDULE TO SHORTER INTER-
VALS TO MATCH THE ENVIRON-
MENT. The most important points of
motorcycle inspection, adjustment,
and lubrication are explained in the
following pages.

this manual is intended to provide
you, the owner, with the necessary
information for completing some of
your own preventive maintenance
and minor repairs.
The tools provided in the ownerÕs tool
kit are to assist you in the perfor-
mance of periodic maintenance.
However, some other tools such as a
