CONTROL FUNCTIONS
CONTROL FUNCTIONS
MAIN SWITCH
Functions of the respective switch po-
sitions are as follows:
ON:
The engine can be started only at this 
position.
OFF:
All electrical circuits are switched off.
Main switch indicator light
The main switch "1" is equipped with 
an indicator light "2" to avoid forget-
ting to turn it off. This light functions 
as follows.
• It lights up with the main switch 
"ON".
• It goes out when the engine in-
creases its speed after being start-
ed.
• It lights up again when the engine is 
stopped.
If the indicator light will not light up 
with the main switch "ON", it shows a 
lack of the battery voltage. Recharge 
the battery.
ENGINE STOP SWITCH
The engine stop switch "1" is located 
on the left handlebar. Continue push-
ing the engine stop switch till the en-
gine comes to a stop.
START SWITCH
The start switch "1" is located on the 
right handlebar. Push this switch to 
crank the engine with the starter.CLUTCH LEVER
The clutch lever "1" is located on the 
left handlebar; it disengages or en-
gages the clutch. Pull the clutch lever 
to the handlebar to disengage the 
clutch, and release the lever to en-
gage the clutch. The lever should be 
pulled rapidly and released slowly for 
smooth starts.
SHIFT PEDAL
The gear ratios of the constant-mesh 
5 speed transmission are ideally 
spaced. The gears can be shifted by 
using the shift pedal "1" on the left 
side of the engine.
KICKSTARTER CRANK
Rotate the kickstarter crank "1" away 
from the engine. Push the starter 
down lightly with your foot until the 
gears engage, then kick smoothly 
and forcefully to start the engine. This 
model has a primary kickstarter crank 
so the engine can be started in any 
gear if the clutch is disengaged. In 
normal practices, however, shift to 
neutral before starting.
THROTTLE GRIP
The throttle grip "1" is located on the 
right handlebar; it accelerates or de-
celerates the engine. For accelera-
tion, turn the grip toward you; for 
deceleration, turn it away from you.FRONT BRAKE LEVER
The front brake lever "1" is located on 
the right handlebar. Pull it toward the 
handlebar to activate the front brake.
REAR BRAKE PEDAL
The rear brake pedal "1" is located on 
the right side of the machine. Press 
down on the brake pedal to activate 
the rear brake.
FUEL COCK
The fuel cock supplies fuel from the 
tank to carburetor and also filters the 
fuel. The fuel cock has the three posi-
tions:
OFF:
With the lever in this position, fuel will 
not flow. Always return the lever to 
this position when the engine is not 
running.
ON:
With the lever in this position, fuel 
flows to the carburetor. Normal riding 
is done with the lever in this position.
RES:
With the lever in this position fuel 
flows to the carburetor from the re-
serve section of the fuel tank after the 
main supply of the fuel has been de-
pleted. Normal riding is possible with 
the lever is in this position, but it is 
recommended to add fuel as soon as 
possible.

MULTI-FUNCTION DISPLAY
COLD STARTER KNOB
When cold, the engine requires a 
richer air-fuel mixture for starting. A 
separate starter circuit, which is con-
trolled by the cold starter knob "1", 
supplies this mixture. Pull the cold 
starter knob out to open the circuit for 
starting. When the engine has 
warmed up, push it in to close the cir-
cuit.
HOT STARTER LEVER
The hot starter lever "1" is used when 
starting a warm engine. Use the hot 
starter lever when starting the engine 
again immediately after it was 
stopped (the engine is still warm). 
Pulling the hot starter lever injects 
secondary air to thin the air-fuel mix-
ture temporarily, allowing the engine 
to be started more easily.
SIDESTAND
This sidestand "1" is used to support 
only the machine when standing or 
transporting it.
• Never apply additional force to 
the sidestand.
• Hold up the sidestand before 
starting out.
MULTI-FUNCTION DISPLAY
Be sure to stop the machine before 
making any setting changes to the 
multi-function display.
The multi-function display is 
equipped with the following:

STARTING AND BREAK-IN
STARTING AND BREAK-IN
FUEL
Always use the recommended fuel as 
stated below. Also, be sure to use 
new gasoline.
Use only unleaded gasoline. The 
use of leaded gasoline will cause 
severe damage to the engine inter-
nal parts such as valves, piston 
rings, and exhaust system, etc.
If knocking or pinging occurs, use a 
different brand of gasoline or higher 
octane grade.
• For refueling, be sure to stop the 
engine and use enough care not 
to spill any fuel. Also be sure to 
avoid refueling close to a fire.
• Refuel after the engine, exhaust 
pipe, etc. have cooled off.
Gasohol (For Canada)
There are two types of gasohol: gas-
ohol containing ethanol and that con-
taining methanol. Gasohol containing 
ethanol can be used if the ethanol 
content does not exceed 10%. Gaso-
hol containing methanol is not recom-
mended by Yamaha because it can 
cause damage to the fuel system or 
vehicle performance problems.
HANDLING NOTE
Never start or run the engine in a 
closed area. The exhaust fumes 
are poisonous; they can cause 
loss of consciousness and death 
in a very short time. Always oper-
ate the machine in a well-ventilated 
area.
• The carburetor on this machine 
has a built-in accelerator pump. 
Therefore, when starting the en-
gine, do not operate the throttle 
or the spark plug will foul.
• Unlike a two-stroke engine, this 
engine cannot be kick started 
when the throttle is open be-
cause the kickstarter may kick 
back. Also, if the throttle is open 
the air/fuel mixture may be too 
lean for the engine to start.
• Before starting the machine, per-
form the checks in the pre-opera-
tion check list.
AIR FILTER MAINTENANCE
According to "CLEANING THE AIR 
FILTER ELEMENT" section in the 
CHAPTER 3, apply the foam-air-filter 
oil or its equivalent to the element. 
(Excess oil in the element may ad-
versely affect engine starting.)
STARTING A COLD ENGINE
This model is equipped with an igni-
tion circuit cut-off system. The engine 
can be started under the following 
conditions.
• When the transmission is in neutral.
• When the clutch is disengaged with 
the transmission in any position. 
However, it is recommended to shift 
into neutral before starting the en-
gine.
1. Inspect the coolant level.
2. Turn the fuel cock to "ON".
3. Push on the main switch to "ON".
4. Shift the transmission into neutral.
5. Fully open the cold starter knob 
"1".
6. Start the engine by pushing the 
start switch or by kicking the kick-
starter crank.
If the engine fails to start by pushing 
the start switch, release the switch, 
wait a few seconds, and then try 
again. Each starting attempt should 
be as short as possible to preserve 
the battery. Do not crank the engine 
more than 10 seconds on any one at-
tempt. If the engine does not start 
with the starter motor, try using the 
kickstarter crank.
• If the starter motor will not turn 
when pushing the start switch, 
stop pushing it immediately and 
kick start the engine in order to 
avoid the load on the motor.
• Do not open the throttle while 
kicking the kickstarter crank. 
Otherwise, the kickstarter crank 
may kick back.
7. Return the cold starter knob to its 
original position and run the en-
gine at 3,000–5,000 r/min for 1 or 
2 minutes.
Since this model is equipped with an 
accelerator pump, if the engine is 
raced (the throttle opened and 
closed), the air/fuel mixture will be too 
rich and the engine may stall. Also 
unlike a two-stroke engine, this model 
can idle.
Do not warm up the engine for ex-
tended periods of time.
STARTING A WARM ENGINE
Do not operate the cold starter knob 
and throttle. Pull the hot starter lever 
"1" and start the engine by pushing 
the start switch or by kicking the kick-
starter crank forcefully with a firm 
stroke. As soon as the engine starts, 
Release the hot starter lever to close 
the air passage. Recommended fuel:
Premium unleaded 
gasoline only with a re-
search octane number 
of 95 or higher.

STARTING AND BREAK-IN
Restarting an engine after a fall
Pull the hot starter lever and start the 
engine. As soon as the engine starts, 
Release the hot starter lever to close 
the air passage.
The engine fails to start
Pull the hot starter lever all the way 
out and while holding the lever, kick 
the kickstarter crank 10 to 20 times to 
clear the engine. Then, restart the en-
gine. Refer to "Restarting an engine 
after a fall".
Observe the following break-in 
procedures during initial operation 
to ensure optimum performance 
and avoid engine damage.
BREAK-IN PROCEDURES
1. Before starting the engine, fill the 
fuel tank with the fuel.
2. Perform the pre-operation checks 
on the machine.
3. Start and warm up the engine. 
Check the idle speed, and check 
the operation of the controls and 
the engine stop switch. Then, re-
start the engine and check its op-
eration within no more than 5 
minutes after it is restarted.
4. Operate the machine in the lower 
gears at moderate throttle open-
ings for five to eight minutes.
5. Check how the engine runs when 
the machine is ridden with the 
throttle 1/4 to 1/2 open (low to me-
dium speed) for about one hour.
6. Restart the engine and check the 
operation of the machine through-
out its entire operating range. Re-
start the machine and operate it 
for about 10 to 15 more minutes.
After the break-in or before each 
ride, you must check the entire ma-
chine for loose fittings and fasten-
ers as per "TORQUE-CHECK 
POINTS". Tighten all such fasten-
ers as required.

CLEANING AND STORAGE
CLEANING AND STORAGE
CLEANING
Frequent cleaning of your machine 
will enhance its appearance, maintain 
good overall performance, and ex-
tend the life of many components.
1. Before washing the machine, 
block off the end of the exhaust 
pipe to prevent water from enter-
ing. A plastic bag secured with a 
rubber band may be used for this 
purpose.
2. If the engine is excessively 
greasy, apply some degreaser to 
it with a paint brush. Do not apply 
degreaser to the chain, sprockets, 
or wheel axles.
3. Rinse the dirt and degreaser off 
with a garden hose; use only 
enough pressure to do the job.
Do not use high-pressure washers 
or steam-jet cleaners since they 
cause water seepage and deterio-
ration seals.
4. After the majority of the dirt has 
been hosed off, wash all surfaces 
with warm water and a mild deter-
gent. Use an old toothbrush to 
clean hard-to-reach places.
5. Rinse the machine off immediate-
ly with clean water, and dry all 
surfaces with a soft towel or cloth.
6. Immediately after washing, re-
move excess water from the 
chain with a paper towel and lubri-
cate the chain to prevent rust.
7. Clean the seat with a vinyl uphol-
stery cleaner to keep the cover 
pliable and glossy.
8. Automotive wax may be applied 
to all painted or chromed surfac-
es. Avoid combination cleaner-
waxes, as they may contain abra-
sives.
9. After completing the above, start 
the engine and allow it to idle for 
several minutes.STORAGE
If your machine is to be stored for 60 
days or more, some preventive mea-
sures must be taken to avoid deterio-
ration. After cleaning the machine 
thoroughly, prepare it for storage as 
follows:
1. Drain the fuel tank, fuel lines, and 
the carburetor float bowl.
2. Remove the spark plug, pour a ta-
blespoon of SAE 10W-40 motor 
oil in the spark plug hole, and re-
install the plug. With the engine 
stop switch pushed in, kick the en-
gine over several times to coat the 
cylinder walls with oil.
3. Remove the drive chain, clean it 
thoroughly with solvent, and lubri-
cate it. Reinstall the chain or store 
it in a plastic bag tied to the frame.
4. Lubricate all control cables.
5. Block the frame up to raise the 
wheels off the ground.
6. Tie a plastic bag over the exhaust 
pipe outlet to prevent moisture 
from entering.
7. If the machine is to be stored in a 
humid or salt-air environment, 
coat all exposed metal surfaces 
with a film of light oil. Do not apply 
oil to rubber parts or the seat cov-
er.
Make any necessary repairs before 
the machine is stored.
