CAUTION:
1. Do not coast for long periods with the engine off,
and do not tow the motorcycle a long distance. Even
with gears in neutral, the transmission is only
properly lubricated when the engine is running.
Inadequate lubrication may damage the
transmission.
2. 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.
Shifting
The transmission lets you control the amount of power you
have available at a given speed for starting, accelerating,
climbing hills, etc. The use of shift pedal is shown in the
illustration (page 3-6).
To shift into NEUTRAL, depress the shift pedal repeatedly
until it reaches the end of its travel (you will feel a stop
when you are in first gear), then raise the pedal slightly.

5-7Engine Break-in
There is never a more important period in the life of your
motorcycle than the period 1.000Km. 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 several hours of running.
During this period, prolonged full throttle operation, or any
condition which might result in excessive heating of the
engine must be avoided.
1. 0 ~ 150 Km:
Avoid operation above 1/3 throttle. Stop the engine and
let it cool for 5 to 10 minutes after every hour of
operation. Vary the speed of the motorcycle from time
to time. Do not operate it at one set throttle position. Your motorcycle’s fuel consumption depends to a large
extent on your riding style. The following tips can help
reduce fuel consumption.
1. Warm up the engine before riding.
2. Turn off the starter lever as soon as possible.
3. Shift up swiftly and avoid high engine speeds during
acceleration.
4. Do not double-clutch or rev the engine while shifting down
and avoid high engine speeds with no load engine.
5. Turn off the engine instead of letting it idle for an extended
lenght of time, i.e. in traffic jams, at traffic lights or railroad
crossings.Tips for reducing fuel consumption

$
The clutch lever free play should be adjusted to 10 ~ 15
mm (0.4 ~ 0.6 in) at the clutch lever end. If the free play is
incorrect, adjust as follows.
1. Loosen the locknut at the handlebar.
2. Turn the adjuster in (A) or out (B) until proper lever free
play is obtained.
3. Tighten the locknut.
4. If the free play is still incorrect, make an adjustment at
the crankcase side.
NOTE:
If proper adjustment cannot be obtained or the clutch does
not work correctly, ask a Yamaha dealer to inspect the
internal clutch mechanism.

Lubricate the pivoting parts.
RECOMMENDED LUBRICANT:
Engine oil SAE 20W50 Throttle cable and grip lubrication
The throttle twist grip assembly should be greased at the
time the cable is lubricated, since the grip must be removed
to get at the end of the throttle cable.
After removing the screws, hold the end of the cable up in
the air and put in several drops of lubricant. With the throttle
grip disassembled, coat the metal surface of the grip
assembly with a suitable all-purpose grease.Brake and shift pedals
