MOTORCYCLE SAFETY
IMPORTANT MESSAGE TO
PARENTS
Your child’s safety is very important to
Honda. That's why we urge you to read this
message before you let any young person
ride this motorcycle. Off-road riding can be
fun. But as with riding a bicycle, bad
judgements can result in injuries, and we
don’t want that to happen! As a parent, you
can help prevent accidents by making good
decisions about if, when, and how your
youngster rides this motorcycle.
Riding Readiness
The first decision you'll need to make is
whether your youngster is ready to ride.
Riding readiness varies widely from one
person to another, and age and size are not
the only factors.
PHYSICAL ABILITY is an important
consideration. For example, riders must be
big enough to hold the motorcycle up, get
on, and comfortably sit on the seat with
both feet touching the ground. They should
also be able to easily reach and work the
brakes, the throttle and all other controls.
ATHLETIC ABILITY is necessary for
riding a motorcycle. Generally speaking,
your youngster should be good at riding a
bicycle before getting on a motorcycle. Can
your youngster judge speeds and distances
on a bicycle and react with proper hand and
foot actions? Anyone who does not have
good coordination,balance, and agility is not
ready to ride this motorcycle.
MENTAL AND EMOTIONAL MATURITY
are requirements for safe riding. Does your
youngster think through problems and
come to logical solutions? On a bicycle,
does your youngster obey safe riding rules ?
Be honest! Young people who take
unnecessary risks, make bad judgements
and don’t obey rules are not ready to ride
this motorcycle.
Instruction and Supervision
If you decide that your youngster is ready to
safely operate this motorcycle, make sure
both of you carefully read and understand
the Owner’s Manual before riding. Also be
sure that your youngster has a helmet and
other appropriate riding equipment and
always wears it when operating the vehicle
or sitting on it.
GOOD INSTRUCTION is an important part
of hands-on training. The teacher can either
be you or another responsible adult who has
experience with off-road motorcycle riding.
(For help in finding a qualified instructor,
talk with your Honda dealer.) Even if you're
not the main teacher, its up to you to
ensure your youngster's safety. Remember,
learning to ride a motorcycle is a gradual
step-by-step process. It takes time, patience
and practice — many hours over a period of
weeks or months.
SUPERVISION is another important
obligation of parents. Even after youngsters
have become skilled off-road riders, they
should always ride with adult supervision. It
helps to regularly remind young riders of
basic safety rules and cautions. And
remember, it’s your responsibility to see
that the vehicle is properly maintained and
kept in safe operating condition.
SAFE AND RESPONSIBLE RIDING must
be an ongoing commitment—by you and
your youngster. When you both put safety
first, you can enjoy more peace of mind, and
your youngster can enjoy more hours of
safe off-road riding.
For your convenience, this CRF80F comes
with an ignition switch and key. Remove the
key when the motorcycle is parked to help
prevent unauthorized use.
IMPORTANT SAFETY INFORMATION
Your motorcycle can provide many years of
service and pleasure—if you take
responsibility for your own safety and
understand the challenges you can meet
while riding.
This motorcycle has been designed for
younger riders, as well as for smaller adults.
However, not all youngsters are physically
or emotionally ready to ride. Therefore,
before parents allow any youngster to ride
this motorcycle, we urge them to carefully
read the Important Message to Parents on
page 1.
There is much that you can do to protect
yourself when you ride. You'll find many
helpful recommendations throughout this
manual. Following are a few that. we
consider most important.
Always Wear a Helmet
I's a proven fact: helmets significantly
reduce the number and severity of head
injuries. So always wear an approved
motorcycle helmet. We also recommend
that you wear eye protection, sturdy boots,
gloves and other protective gear (page 5).
Never Carry a Passenger
Your motorcycle is designed for one person
only. There are no handholds, footrests, or
seat for a second person—so never carry a
passenger. A passenger could interfere with
your ability to move around to maintain
your balance and control of the motorcycle.
Ride Off-Road Only
Your motorcycle is designed and
manufactured for off-road use only. The
tyres are not made for pavement, and the
motorcycle does not have turn signals and
other features required for use on public
roads. If you need to cross a paved or public
road, get off and walk your motorcycle
across.
Take Time to Learn and Practice
Developing off-road riding skills is a gradual,
step-by-step process. Start by practicing at
low speeds in a safe area and slowly build
your skills. Personal instruction from an
experienced rider can also be valuable.
If you need assistance, ask your dealer
about riding groups in your area.
Be Alert for Off-Road Hazards
The terrain can present a variety of
challenges when you ride off-road.
Continually “read” the terrain for
unexpected turns, drop-offs, rocks, ruts, and
other hazards. Always keep your speed low
enough to allow time to see and react to
hazards.
Ride Within Your Limits
Pushing the limits is another major cause of
motorcycle accidents. Never ride beyond
your personal abilities or faster than
conditions warrant. Remember that alcohol,
drugs, fatigue and inattention can
significantly reduce your ability to make
good judgements and ride safely.
Don’t Drink and Ride
Alcohol and riding don’t mix. Even one
drink can reduce your ability to respond to
changing conditions, and your reaction time
gets worse with every additional drink. So
dont drink and ride, and don’t let your
friends drink and ride either.
Keep Your Bike in Safe Condition
For safe riding, it’s important to inspect
your motorcycle before every ride and
perform all recommended maintenance.
Never exceed load limits, and only use
accessories that have been approved by
Honda for this motorcycle. See page 7 for
more details.
Others
e This motorcycle is not equipped with
lights. Don't ride at night.
PROTECTIVE APPAREL
For your safety, we strongly recommend
that you always wear an approved
motorcycle helmet, eye protection, boots,
gloves, long pants, and a long-sleeved jersey,
shirt or jacket whenever you ride. Although
complete protection is not possible, wearing
proper gear can reduce the chance of injury
when you ride.
Following are suggestions to help you
choose proper gear.
EN CC
Not wearing a helmet increases the
chance of serious injury or death in a
crash.
Be sure you always wear a helmet,
eye protection and other protective
apparel when you ride.
Helmets and Eye Protection
Your helmet is your most important piece of
riding gear because it offers the best
protection against head injuries. A helmet
should fit your head comfortably and have a
chin strap that can be tightened securely.
An open-face helmet offers some protection,
but a full-face helmet offers more. Always
wear a face shield or goggles to protect
your eyes and help your vision.
Additional Riding Gear
In addition to a helmet and eye protection,
we also recommend:
® Sturdy off-road motorcycle boots to help
protect your feet, ankles, and lower legs.
* Offroad motorcycle gloves to help
protect your hands.
e Riding pants with knee and hip pads, a
riding jersey with padded elbows, and a
chest/shoulder protector.
LOAD LIMITS AND GUIDELINES
Your Honda was designed as a rider-only
motorcycle. It was not designed to carry a
passenger or cargo. A passenger or cargo
could interfere with your ability to move
around to maintain your balance and control
of the motorcycle.
In addition, exceeding the weight limits or
carrying an unbalanced load can seriously
affect your motorcycle’s handling, braking,
and stability. Adding accessories or making
modifications that change this motorcycle’s
design and performance can also make it
unsafe. Also, the weight of any accessories
will reduce the maximum load the
motorcycle can carry.
The following pages give more specific
information on loading, accessories and
modifications.
Loading
How much weight you put on your
motorcycle, and how you load it, are
important to your safety. If you decide to
carry cargo, you should be aware of the
following information.
AWARNING
Overloading or carrying a passenger
can cause a crash and you can be
seriously hurt or killed.
Follow all load limits and other loading
guidelines in this manual.
Load Limits
Following are the load limits for your
motorcycle:
Maximum weight capacity:
100 kg (220 Ibs)
Includes the weight of the rider and any
accessories
Loading Guidelines
As discussed on page 7, we recommend
that you do not carry any cargo on this
motorcycle. However, if you decide to carry
cargo, ride at reduced speeds and follow
these common-sense guidelines:
e Keep cargo small and light. Make sure it
cannot easily be caught on brush or other
objects, and that it does not interfere with
your ability to shift position to maintain
balance and stability.
* Place weight as close to the center of the
motorcycle as possible.
* Do not attach large or heavy items (such
as a sleeping bag or tent) to the
handlebar, fork, or front fender.
e Make sure that all cargo is Ней down
securely.
e Never exceed the maximum weight limit.
e Check that both tyres are properly
inflated (page 27).
Accessories and Modifications
Modifying your motorcycle or using non-
Honda accessories can make your
motorcycle unsafe. Before you consider
making any modifications or adding an
accessory, be sure to read the following
information.
A WARNING
Improper accessories or modifications
can cause a crash in which you can be
seriously hurt or killed.
Follow all instructions in this owners
manual regarding accessories and
modifications.
Accessories
We strongly recommend that you use only
genuine Honda accessories that have been
specifically designed and tested for your
motorcycle. Because Honda cannot test all
other accessories, you must be personally
responsible for proper selection, installation
and use of non-Honda accessories. Check
with your dealer for assistance and always
follow these guidelines:
e Make sure the accessory does not reduce
ground clearance and lean angle, limit
suspension travel or steering travel, alter
your riding position or interfere with
operating any controls.
Modifications
We strongly advise you not to remove any
original equipment or modify your
motorcycle in any way that would change its
design or operation. Such changes could
seriously impair your motorcycle’s handling,
stability and braking, making it unsafe to
ride.
Removing or modifying your exhaust
system (such as the spark arresters or
mufflers) or other equipment can also make
your motorcycle illegal.

FUEL
Fuel Valve
The three way fuel valve (1) is on the left
side near the carburetor.
OFF
With the fuel valve in the OFF position, fuel
cannot flow from the tank to the carburetor.
Turn the valve OFF whenever the
motorcycle is not in use.
ON
With the fuel valve in the ON position, fuel
will flow from the main fuel supply to the
carburetor.
RES
With the fuel valve in the RES position, fuel
will flow from the reserve fuel supply to the
carburetor. Use the reserve fuel only when
the main supply is gone. Refill the tank as
soon as possible after switching to RES.
The reserve fuel supply is:
0.7 2 (0.18 US gal , 0.15 Imp gal)
22
Remember to check that the fuel valve is in
the ON position each time you refuel. If the
valve is left in the RES position, you may
run out of fuel with no reserve.
A
(1)
(1) Fuel valve
Fuel Tank
The fuel tank capacity including the reserve

A WARNING
Petrol is highly flammable and
explosive. You can be burned or
seriously injured when handling fuel.
e Stop the engine and keep heat,
sparks, and flame away.
e Refuel only outdoors.
e Wipe up spills immediately.
(1) Fuel fill cap
(2) Breather tube

23
For U:
Use unleaded or low-lead petrol with a
research octane number of 91 or higher.
We recommend that you use unleaded
petrol because it produces fewer engine and
spark plug deposits and extends the life of
exhaust system components.
For Mexico:
Use unleaded or low-lead petrol with a
research octane number of 88 or higher.
Recommended — Extra petrol.
24
If “spark knock” or “pinking” occurs at a
steady engine speed under normal load,
change brands of petrol. If spark knock or
pinking persists, consult your Honda dealer.
Failure to do so is considered misuse, and
damage caused by misuse is not covered by
Honda's Limited Warranty.
Occasionally you may experience light
spark knock while operating under heavy
loads. This is no cause for concern, it simply
means your engine is operating efficiently.
Petrol Containing Alcohol
If you decide to use a petrol containing
alcohol (gasohol), be sure it’s octane rating
is at least as high as that recommended by
Honda. There are two types of “gasohol”:
one containing ethanol, and the other
containing methanol. Do not use petrol that
contains more than 10 % ethanol. Do not use
petrol containing methanol (methyl or wood
alcohol) that does not also contain
cosolvents and corrosion inhibitors for
methanol. Never use petrol containing more
than 5 % methanol, even if it has cosolvents
and corrosion inhibitors.
Fuel system damage or engine performance
problems resulting from the use of fuels
that contain alcohol is not covered under
the warranty. Honda cannot endorse the
use of fuels containing methanol since
evidence of their suitability is as yet
incomplete.
Before buying fuel from an unfamiliar
station, try to find out if the fuel contains
alcohol. If it does, confirm the type and
percentage of alcohol used. If you notice
any undesirable operating symptoms while
using a petrol that contains alcohol, or one
that you think contains alcohol, switch to a
petrol that you know does not contain
alcohol.
25
ENGINE OIL
Engine Oil Level Check
Check the engine oil level each day before
operating the motorcycle.
The oil filler cap/dipstick (1) is at the rear
of the right crankcase cover and contains a
dipstick for measuring the oil level. Oil level
must be maintained between the upper (2)
and lower (3) level marks on the oil filler
cap/ dipstick.
1. Hold the motorcycle upright on firm level
ground.
2. Start the engine and let it idle for 3—5
minutes.
3. Stop the engine. After 2—3 minutes,
remove the oil filler cap/dipstick, wipe it
clean, and reinsert the oil filler cap/
dipstick without screwing it in. Remove
the oil filler cap/dipstick. The oil level
should be between the upper and lower
level marks on the oil filler cap/dipstick.
26
4. Tf required, add the specified oil (page
56 ) up to the upper level mark. Do not
overfill.
5. Reinstall the oil filler cap/dipstick. Check
for oil leaks.
Running the engine with insufficient oil can
cause serious engine damage.

TYRES
To safely operate your motorcycle, the tyres
must be the proper type (off-road) and size,
in good condition with adequate tread, and
correctly inflated.
A WARNING
Using tyres that are excessively worn
or improperly inflated can cause a
crash in which you can be seriously
hurt or killed.
Follow all instructions in this owners
manual regarding tyre inflation and
maintenance.
Air Pressure
Properly inflated tyres provide the best
combination of handling, tread life, and
riding comfort. Generally, underinflated
tyres wear unevenly, adversely affect
handling, and are more likely to fail from
being overheated. Underinflated tyres can
also cause wheel damage in rocky terrain.
Overinflated tyres make your motorcycle
ride harshly, are more prone to damage
from surface hazards, and wear unevenly.
Make sure the valve stem caps are secure.
If necessary, install a new cap.
27
Always check air pressure when your tyres
are “cold.” If you check air pressure when
your tyres are “warm”—even if your
motorcycle has only been ridden for a few
miles —the readings will be higher. If you
let air out of warm tyres to match the
recommended cold pressures, the tyres will
be underinflated.
The recommended “cold” tyre pressures
are:
Front 100 kPa (1.0 kgf/cm? , 15
| psi)
Rear 100 kPa (1.0 kgf/cm? , 15
psi)
28
Inspection
Whenever you check the tyre pressures,
you should also examine the tyre treads and
sidewalls for wear, damage, and foreign
objects:
Look for:
® Bumps or bulges in the side of the tyre or
the tread. Replace the tyre if you find any
bumps or bulges.
e Cuts, splits or cracks in the tyre. Replace
the tyre if you can see fabric or cord.
® Excessive tread wear.
Also, if you hit a pothole or hard object, pull
to the side of the road as soon as you can
safely and carefully inspect the tyres for
damage.
Tread Wear
Replace tyres before tread depth at the
center of the tyre reaches the following (1)
limit:
Minimum tread depth
Front: 3.0 mm (0.12 in)
Rear: 3.0 mm (0.12 in)
(1) Tyre tread depth
29
Tube Repair and Replacement
If a tube is punctured or damaged, you
should replace it as soon as possible. A tube
that is repaired may not have the same
reliability as a new one, and it may fail while
you are riding.
If you need to make a temporary repair by
patching a tube or using an aerosol sealant,
ride cautiously at reduced speed and have
the tube replaced before you ride again.
Any time a tube is replaced, the tyre should
be carefully inspected as described on page
28 .
30
Tyre Replacement
The tyres that came on your motorcycle
were designed to match the performance
capabilities of your motorcycle and provide
the best combination of handling, braking,
durability and comfort.
A WARNING
Installing improper tyres on your
motorcycle can affect handling and
stability. This can cause a crash in
which you can be seriously hurt or
Killed. .
Always use the size and type of tyres
recommended in this owner's manual.
The recommended tyres for your
motorcycle are:
Front: 2.50—16 4PR
Rear: 3.60— 14 4PR
Type: bias-ply, tube
Whenever you replace a tyre, use one that
is equivalent to the original and be sure the
wheel is balanced after the new tyre is
installed.
Also remember to replace the inner tube
whenever you replace a tyre. The old tube
will probably be stretched, and if installed in
a new tyre, it could fail.

PRE-RIDE INSPECTION
For your safety, it is very important to take
a few moments before each ride to walk
around your motorcycle and check its
condition. If you detect any problem, be
sure you take care of it, or have it corrected
by your Honda dealer.
AWARNING
improperly maintaining this motorcycle
or failing to correct a problem before
riding can cause a crash in which you
can be seriously hurt or killed.
Always perform a pre-ride inspection
before every ride and correct any
problems.
1. Engine oil level—add engine oil if
required (page 26). Check for leaks.
2. Fuel level fill fuel tank when necessary
(page 23). Check for leaks.
3. Front and rear brakes— check operation
and if necessary, adjust freeplay (pages
14 — 18).
4. Tyres—check condition and pressure
(pages 27 — 31).
5. Spokes and rim locks — check and tighten
if necessary (page 72 ).
6. Drive chain — check condition and slack
(page 67 ). Adjust and lubricate if
necessary.
7. Chain slider — check slider wear (page
68 ).
8. Throttle — check for smooth opening and

36
STARTING THE ENGINE
Always follow the proper starting procedure
described below.
This motorcycle can be kickstarted with the
transmission in gear by disengaging the
clutch before operating the kickstarter.
Your motorcycle’s exhaust contains
poisonous carbon monoxide gas. High
levels of carbon monoxide can collect
rapidly in enclosed areas such as a garage.
Do not run the engine with the garage door
closed. Even with the door open, run the
engine only long enough to move your
motorcycle out of the garage.
Preparation
Before starting, insert the key and turn the
ignition switch ON.
Make sure that the transmission is in
neutral. Turn the fuel valve ON.
37
Starting Procedure
To restart a warm engine, follow the
procedure for “High Air Temperature.”
Normal Air Temperature
10° — 35° С (50° —95° Е)
1. Pull the choke lever (1) up all the way to
Fully ON (A).

(B) Fully OFF
(1) Choke lever
38
2. With the throttle slightly open, operate
the kickstarter. Kick from the top of the
stroke through to the bottom with a rapid,
continuous motion.
Allowing the kickstarter to snap back freely
against the pedal stop can damage the
engine case.
3. Warm up the engine by opening and
closing the throttle slightly.
4. About a quarter minute after the engine
starts, push the choke lever (1) down all
the way to Fully OFF (B).
5. If idling is unstable, open the throttle
slightly.
High Air Temperature
35°C (95°F) or above
1. Do not use the choke.
2. Start the engine following step 2 under
“Normal Air Temperature.”
Low Air Temperature
10°C (50°F) or below
1. Follow steps 1—2 under “Normal Air
Temperature”.
2. Warm up the engine by opening and
closing the throttle slightly.
3. Continue warming up the engine until it
runs smoothly and responds to the
throttle, when the choke lever (1) is at
Fully OFF (B).
Extended use of the choke may impair
piston and cylinder wall lubrication and
damage the engine.
39
Flooded Engine
If the engine fails to start after repeated
attempts, it may be flooded with excess fuel.
To clear a flooded engine, push the choke
lever down to Fully OFF (B). Open the
throttle fully and crank the engine several
times with the kickstarter while pushing the
engine stop button. Release the engine stop
button and follow the “High Air
Temperature” Starting Procedure (page

40
RUNNING-IN
Help assure your motorcycle's future
reliability and performance by paying extra
attention to how you ride during the first
operating day or 25 km (15 miles).
During this period, avoid full-throttle starts
and rapid acceleration.
RIDING
Review Motorcycle Safety (pages 1 — 10)
before you ride.
Make sure the side stand is fully retracted
before riding the motorcycle. If the stand is
extended, it may interfere with control
during a left turn.
Make sure you understand the function of
the side stand mechanism. (See MAIN-
TENANCE SCHEDULE on page 51 and
explanation for SIDE STAND on page 79 ).
1. After the engine has been warmed up,
the motorcycle is ready for riding.
2. While the engine is idling, pull in the
clutch lever and depress the shift lever to
shift into 1st (low) gear.
3. Slowly release the clutch lever and at the
same time gradually increase engine
speed by opening the throttle.
Coordination of the throttle and clutch
lever will assure a smooth positive start.
4. When the motorcycle attains a moderate
speed, close the throttle, pull in the clutch
lever and shift to 2nd gear by raising the
shift lever.
This sequence is repeated to
progressively shift to 3rd, 4th and 5th
(top) gears.
41
5. Raise the shift lever to shift to a higher
gear and depress the shift lever to shift to
a lower gear. Each stroke of the shift
lever engages the next gear in sequence.
The shift lever automatically returns to
the horizontal position when released.
42
* Do not downshift when traveling at a
speed that would force the engine to
overrev in the next lower gear; the rear
wheel may lose traction, resulting in a
possible loss of vehicle control.
® Do not shift gears without disengaging
the clutch and closing the throttle. The
engine and drive train could be damaged
by overspeed and shock.
* Do not tow the motorcycle or coast for
long distances while the engine is off.
The transmission will not be properly
lubricated and damage may result.
e Do not run the engine at high rpm with
the transmission in neutral or the clutch
lever pulled in. Serious engine damage
may result.
HIGH ALTITUDE RIDING
(Except Mexico)
When operating this motorcycle at high
altitude the air-fuel mixture becomes overly
rich. Driveability and performance may be
reduced and fuel consumption increased.
The carburetor can be modified to
compensate for this high altitude richness,
however it must be returned to standard
specifications before extended operation at
low altitudes (below 1,200 m, 4,000 feet).
See your Honda dealer for this high altitude
modification.
Sustained operation at lower altitudes with
high altitude carburetor modifications may
cause engine overheating and damage.
LOW ALTITUDE RIDING
(Mexico only)
When operating this motorcycle at low
altitude, the air-fuel mixture becomes overly
lean. Below 1,000 m (3,300 feet), driveability
and performance may be reduced. The
carburetor can be modified to compensate
for this low altitude leanness. However, the
carburetor must be returned to standard
factory specifications when higher altitude
riding is desired. See your Honda dealer for
low altitude adjustments.
Sustained operation at altitudes above 1,500
m (5,000 feet) with low altitude carburetor
modifications may cause flooded engine.
BRAKING
For normal braking, gradually apply both
the front and rear brakes while
downshifting to suit your road speed.
For maximum deceleration, close the
throttle and apply the front and rear brakes
firmly. Pull in the clutch lever before
coming to a complete stop to prevent
stalling the engine.
Important Safety Reminders:
* Independent operation of only the brake
lever or brake pedal reduces stopping
performance.
® Extreme application of the brake controls
may cause wheel lock, reducing control of
the motorcycle.
* When possible, reduce speed or brake
before entering a turn; closing the
throttle or braking in mid-turn may cause
wheel slip. Wheel slip will reduce control
of the motorcycle.
e When riding in wet or rainy conditions, or
on loose surfaces, the ability to maneuver
and stop will be reduced. All of your
actions should be smooth under these
conditions. Rapid acceleration, braking or
turning may cause loss of control. For
your safety, exercise extreme caution
when braking, accelerating or turning.
e When descending a long, steep grade,
use engine compression braking by down-
shifting, with intermittent use of both
brakes.
Continuous brake application can
overheat the brakes and reduce their
effectiveness.
PARKING
1. After stopping the motorcycle, shift the
transmission into neutral and turn the
fuel valve OFF. Push the engine stop
button in and hold it in until the engine
stops completely.
2. Use the side stand to support the
motorcycle while parked.
Park the motorcycle on firm, level ground to
prevent it from falling over.
If you must park on a slight incline, aim the
front of the motorcycle uphill to reduce the
possibility of rolling off the side stand or
overturning.
3. Turn the ignition switch OFF and remove
the key.
ANTI-THEFT TIPS
1. Be sure the registration information for
your motorcycle is accurate and current.
2. Park your motorcycle in a locked garage
whenever possible.
3. Use an additional anti-theft device of
good quality.
4. Put your name, address and phone
number in this Owner's Manual and keep
it on your motorcycle at all times. Many
times stolen motorcycles are identified by
information in the Owners Manuals
which are still with them.

MAINTENANCE
THE IMPORTANCE OF
MAINTENANCE
A well-maintained motorcycle is essential
for safe, economical, and trouble-free riding.
It will also help reduce air pollution. Careful
pre-ride inspections and good maintenance
are especially important because your
motorcycle is designed to be ridden over
rough off-road terrain.
To help you properly care for your
motorcycle, this section of the manual
provides a Maintenance Schedule.
The service intervals in this schedule are
based on average riding conditions.
More frequent service is needed if you
subject your motorcycle to severe use (such
as competition) or ride in unusually wet or
dusty areas.
46
Frequent servicing of the air cleaner is
especially important to help you avoid a
possible costly engine repair.
If your motorcycle overturns or becomes
involved in a crash, be sure your Honda
dealer inspects all major parts, even if you
are able to make some repairs.
EEE
Improperly maintaining this motorcycle
or failing to correct a problem before
you ride can cause a crash in which
you can be seriously hurt or killed.
Always follow the inspection and
maintenance recommendations and
schedules in this owners manual.
MAINTENANCE SAFETY
This section includes instructions on some
important maintenance tasks. You can
perform some of these tasks with the tools
provided — if you have basic mechanical
skills.
Other tasks that are more difficult and
require special tools are best performed by
professionals. Wheel removal should
normally be handled only by a Honda
technician or other qualified mechanic;
instructions are included in this manual only
to assist in emergency service.
Some of the most important safety
precautions follow. However, we cannot
warn you of every conceivable hazard that
can arise in performing maintenance. Only
you can decide whether or not you should
perform a given task.
A WARNING
Failure to properly follow maintenance
instructions and precautions can
cause you to be seriously hurt or killed.
Always follow the procedures and
precautions in this owner's manual.
47
SAFETY PRECAUTIONS
o Make sure the engine is off before you
begin any maintenance or repairs. This
will help eliminate several potential
hazards:
+ Carbon monoxide poisoning from
engine exhaust.
Be sure there is adequate ventilation
whenever you operate the engine.
+ Burns from hot parts.
Let the engine and exhaust system cool
before touching.
* Injury from moving parts.
Do not run the engine unless instructed
to do so.
e Read the instructions before you begin,
and make sure you have the tools and
skills required.
e To help prevent the motorcycle from
falling over, park it on a firm, level
surface, using the side stand or a
maintenance stand to provide support.
48
e To reduce the possibility of a fire or
explosion, be careful when working
around petrol. Use only nonflammable
solvent, not petrol, to clean parts. Keep
cigarettes, sparks and flames away from
all fuel-related parts.
Remember that your Honda dealer knows
your motorcycle best and is fully equipped
to maintain and repair it.
To ensure the best quality and reliability,
use only new genuine Honda parts or their
equivalents for repair and replacement.
MAINTENANCE SCHEDULE
Perform the Pre-ride Inspection (page 35 ) at each scheduled maintenance period.
I. INSPECT AND CLEAN, ADJUST, LUBRICATE OR REPLACE IF NECESSARY
C: CLEAN R:REPLACE A:ADJUST L: LUBRICATE
The following Maintenance Schedule specifies all maintenance required to keep your motorcycle in peak operating

Engine Oil
Engine oil quality is the chief factor
affecting engine service life. Change the
engine oil as specified in the maintenance
schedule (page 50 ).
When running in very dusty conditions, oil
changes should be performed more
frequently than specified in the
maintenance schedule.
Please dispose of used engine oil in a
manner that is compatible with the
environment. We suggest you take it in a
sealed container to your local recycling
center or service station for reclamation. Do
not throw it in the trash or pour it on the
ground or down a drain.
Used engine oil may cause skin cancer if
repeatedly left in contact with the skin for
prolonged periods. Although this is unlikely
unless you handle used oil on a daily basis,
it is still advisable to thoroughly wash your
hands with soap and water as soon as possi-
ble after handling used oil.
Changing the oil requires a torque wrench.
If you do not have it and the necessary skill,
we recommend that you have your Honda
dealer perform this service.
If a torque wrench is not used for this
installation, see your Honda dealer as soon
as possible to verify proper assembly.
Change the engine oil with the engine at
normal operating temperature and the
motorcycle on its side stand to assure
complete and rapid draining.
59
1. Remove the oil filler cap/dipstick from
the right crankcase cover.
2. Place a drain pan under the crankcase
and remove the oil drain bolt (1).
3. Operate the kickstarter several times
while pressing the engine stop button to
drain any oil which may be left in the
engine.
4. Check that the sealing washer (2) on the
drain bolt is in good condition and install
the bolt. Replace the sealing washer
every other time the oil is changed, or
each time if necessary.
Oil Drain Bolt Torque:
24 N-m (2.5 kgf-m, 18 Ibf-ft)
5. Fill the crankcase with the recommended
grade oil; approximately:
0.9 8 (1.0 US at , 0.8 mp qt)

SPARK PLUG
Refer to the Safety Precautions on page 48 .
Recommended plugs:
Standard:
CR7HSA (NGK) or
U22FSR—U (DENSO)
For cold climate: (Below 5°C, 41°F)
CR6HSA (NGK) or
U20FSR — U (DENSO)
For extended high speed riding:
CR8HSA (NGK) or
U24FSR—U (DENSO)
For most riding conditions this spark plug
heat range number is satisfactory. However,
if the motorcycle is going to be operated for
extended periods at high speeds or near
maximum power in hot climates, the spark
plug should be changed to a colder heat
range (a higher number).
Never use a spark plug with an improper
heat range. Severe engine damage could
result.
1. Disconnect the spark plug cap.
2. Clean any dirt from around the spark plug
base.
3. Remove the spark plug.
4. Visually inspect the spark plug electrodes
for wear. The center electrode should
have square edges and the side electrode
should not be eroded.
5. Discard the spark plug if there is
apparent wear or if the insulator is
cracked or chipped.
61
6. Check the spark plug gap (1) using a
wire-type feeler gauge. If adjustment is
necessary, bend the side electrode (2)
carefully.
The gap should be:
0.6—0.7 mm (0.02 —0.03 in)

7. Make sure the plug washer is in good
condition.
8. With the plug washer attached, thread
the spark plug in by hand to prevent
cross-threading.
9. Tighten the spark plug:
e If the old plug is good:
1/8 turn after it seats.
e If installing a new plug, tighten it twice
to prevent loosening:
a) First, tighten the plug:
NGK: 1 turn after it seats.
DENSO: 3/4 turn after it seats.
b) Then loosen the plug.
¢) Next, tighten the plug again:
1/8 turn after it seats.
An improperly tightened spark plug can
damage the engine. If a plug is too loose, a
piston may be damaged. If a plug is too tight,
the threads may be damaged.
10. Reinstall the spark plug cap. Take care to
avoid pinching any cables or wires.
IDLE SPEED
Refer to the Safety Precautions on page 48 .
Idle Speed:
The engine must be at normal operating
temperature for accurate idle speed
adjustment. 10 minutes of stop-and-go riding
is sufficient.
Do not attempt to compensate for faults in
other systems by adjusting idle speed. See
your Honda dealer for regularly scheduled
carburetor adjustments.

DRIVE CHAIN
Refer to the Safety Precautions on page 48 .
The service life of the drive chain is
dependent upon proper lubrication and
adjustment. Poor maintenance can cause
premature wear or damage to the drive
chain and sprockets.
The drive chain should be checked and
lubricated as part of the Pre-ride Inspection
(page 35). Under severe usage, or when
the motorcycle is ridden in unusually dusty
or muddy areas, more frequent
maintenance will be necessary.
Inspection:
1. Turn the engine off, place the motorcycle
on its side stand and shift the
transmission into neutral.
2. Check slack in the lower drive chain run
midway between the sprockets.
Drive chain slack should be adjusted to
allow the following vertical movement by
hand:
25—35 mM (1.0— 1.4 in)
3. Roll the motorcycle forward. Stop. Check
the drive chain slack. Repeat this
procedure several times. Drive chain
slack should remain constant. If the chain
is slack only in certain sections, some
links are kinked and binding. Binding and
kinking can frequently be eliminated by
lubrication.
Excessive chain slack may allow the drive
chain to damage the engine cases.

5. Measure a section of the drive chain to
determine whether the chain is worn
beyond its service limit. Remove the drive
chain and measure the distance between
a span of pins from pin center to pin
center. If the distance exceeds the service
limit, the chain is worn out and should be
replaced.

If the drive chain or sprockets are
excessively worn or damaged, they should
be replaced. Never use a new chain with
worn sprockets; rapid chain wear will result.
Adjustment:
If the drive chain requires adjustment, the
procedure is as follows:
1. Place a support block under the engine to
raise the rear wheel off the ground.
2. Loosen the rear axle nut (1).

chain slack.
Align the chain adjuster index marks (3)
with the corresponding scale graduations
(4) on both sides of the swingarm.
If the drive chain slack is excessive when
the rear axle is moved to the furthest limit
of adjustment, the drive chain is worn and
must be replaced.

If a torque wrench is not used for this
installation, see your Honda dealer as soon
as possible to verify proper assembly.
Lubrication:
Use SAE 80 or 90 gear oil or a commercially
prepared drive chain lubricants in
preference to motor oil or other lubricants.
Saturate each chain link joint so that the
lubricant penetrates between the link plates,
pins, bushings, and rollers.
Removal and Cleaning:
When the drive chain becomes dirty, it
should be removed and cleaned prior to
lubrication.
1. With the engine off, carefully remove the
master link retaining clip (1) with a pair
of pliers. Do not bend or twist the clip.
Remove the master link. Remove the
drive chain from the motorcycle.
2. Clean the drive chain in high flash-point
solvent and allow it to dry. Inspect the
drive chain for possible wear or damage.
Replace any chain that has damaged
rollers, loose fitting links, or otherwise
appears unserviceable.
Never use petrol or low flash point solvents
for cleaning the drive chain. A fire or
explosion could result.
3. Inspect the sprocket teeth for possible
wear or damage.
4. Lubricate the drive chain (page 70).
5. Pass the chain over the sprockets and join
the ends of the chain with the master link.
For ease of assembly, hold the chain ends
against adjacent rear sprocket teeth while
inserting the master link.
The master link is the most critical part
affecting the security of the drive chain.
Master links are reusable, if they remain
in excellent condition, but it is
recommended that a new master link
retaining clip be installed whenever the
drive chain is reassembled.
Install the master link retaining clip so
that the closed end of the clip will face
the direction of forward wheel rotation.

CLEANING
Clean your motorcycle regularly to protect
the surface finishes and inspect for damage,
wear and oil leakage.
Avoid cleaning products that are not
specifically designed for motorcycle or
automobile surfaces.
They may contain harsh detergents or
chemical solvents that could damage the
metal, paint, and plastic on your motorcycle.
If your motorcycle is still warm from recent
operation, give the engine and exhaust
system time to cool off.
We recommend avoiding the use of high
pressure water spray (typical in coin-
operated car washes).
High pressure water (or air) can damage
certain parts of the motorcycle.
80
High pressure washer spray can damage
certain parts of your motorcycle. If you use
a high pressure washer, avoid spraying the
following areas:
Wheel Hubs
Muffler Outlet
Under Seat
Engine Stop Button
Under Fuel Tank
Drive Chain
Carburetor
Ignition Switch
Washing the motorcycle
1. Rinse the motorcycle thoroughly with
cool water to remove loose dirt.
2. Clean the motorcycle with a sponge or
soft cloth using cool water.

and electrical parts.
3. Clean the plastic parts using a cloth or
sponge dampened with a solution of mild
detergent and water. Rub the soiled area
gently rinsing it frequently with fresh
water.
Take care to keep brake fluid or chemical
solvents off the motorcycle.
They will damage the plastic and painted
surfaces.
4. After cleaning, rinse the motorcycle
thoroughly with plenty of clean water.
Strong detergent residue can corrode
alloy parts.
5. Dry the motorcycle, start the engine, and
let it run for several minutes.
6. Test the brakes before riding the
motorcycle. Several applications may be
necessary to restore normal braking
performance.
7. Lubricate the drive chain immediately
after washing and drying the motorcycle.
Braking efficiency may be temporarily
impaired immediately after washing the
motorcycle.
Anticipate longer stopping distance to avoid
a possible accident.
81
Finishing Touches
After washing your motorcycle, consider
using a commercially-available spray
cleaner /polish or quality liquid or paste wax
to finish the job. Use only a non-abrasive
polish or wax made specifically for
motorcycles or automobiles. Apply the
polish or wax according to the instructions
on the container.
82
STORAGE GUIDE
Extended storage, such as for winter,
requires that you take certain steps to
reduce the effects of deterioration from
non-use of the motorcycle. In addition,
necessary repairs should be made BEFORE

3. To prevent rusting in the cylinder,
perform the following:
* Remove the spark plug cap from the
spark plug. Using tape or string, secure
the cap to any convenient plastic body
part so that it is positioned away from
the spark plug.
® Remove the spark plug from the
engine and store it in a safe place. Do
not connect the spark plug to the spark
plug cap.
® Pour a tablespoon (15-20 cm”) of
clean engine oil into the cylinder and
cover the spark plug hole with a piece
of cloth.
e Crank the engine several times to
distribute the oil.
e Reinstall the spark plug and spark plug
cap.
4. Wash and dry the motorcycle. Wax all
painted surfaces. Coat chrome with
rustinhibiting oil.
