Engine Oil Level Check
Check the engine oil level each day before riding the motorcycle. The level must be maintained between
the upper (2) and lower (3) marks on the dipstick (1).
1. Start the engine and let it idle for a few minutes.
2. Stop the engine and hold the motorcycle in an upright position on firm, level ground.
3. After a few minutes, remove the oil filler cap/dipstick, wipe it clean, and reinsert the dipstick
without screwing it in. The oil level should be between the upper and lower marks on the
dipstick.
4. If required, add the specified oil up to the upper level mark. Do not overfill.
5. Reinstall the oil filler cap/dipstick, check for oil leaks.
CAUTION
Running the engine with insufficient oil can cause serious engine damage.
TYRES
Proper air pressure will provide maximum stability, riding comfort and tire life. Check tire pressure
frequently and adjust if necessary.
NOTE
Tire pressure should be checked before you ride while the tyres are cold.
Select the right replacement tire in accordance with the following specifications:
Cold tire
pressures kPa ( kg/cm2, psi )
Front: 175 ( 1.75, 25 )
Rear : 225 ( 2.25, 33 )
Tire size
Front: 2.75 - 17 41P
Rear : 2.75 - 17 41P
Check the tires for cuts, embedded nails, ore other sharp objects. See your authorized Honda Dealer for
replacement of damaged tires or punctured inner tubes.
WARNING
•
Do not attempt to patch a damaged tire or inner tube. Wheel balance
and tire reliability may be impaired.
Improper tire inflation will cause abnormal tread wear and create a
safety hazard. Under inflation may result in the tire slopping on, or
coming off of the rim causing tire deflation that may result in a loss of
vehicle control.
Operation with excessively worn tire is hazardous and will adversely
affect traction and handling.

Starting Procedure
Cold engine
1. Raise the choke lever (1) to Fully ON (A).
2. Open the throttle slightly and operate the kick starter with the right foot, starting from the top of
the stroke and following through to the bottom with a rapid and continuous kick.
CAUTION
Do not allow the kick starter to snap back freely against the pedal stop
as engine case damage could result.
3. Warm up the engine at approx. 1,500 rpm until it runs smoothly with the choke lever Fully OFF
(B).
Starting in Extremely Cold Weather
Prime the engine before starting by cranking the engine several times with the kick starter. The ignition
switch should be OFF, the choke lever Fully ON (A) and the throttle opened slightly.
Flooded Engine
If the engine fails to start after several repeated attempts, it may have become flooded with excess
fuel. To clear the engine, turn off the engine stop switch and lower the choke lever to Fully OFF (B).
Open the throttle fully and crank the engine several times with the kick starter. Turn the engine stop
switch to RUN and open the throttle slightly; start the engine using the kick starter.
RUNNING-IN
During the first 1,000 km ( 600 miles ) , do not operate the motorcycle at more than 80 % of the
maximum speed in any gear. A void full throttle operation, and do not operate for a long time at one
speed. During initial running in, newly machined surfaces will be in contact with each other and these
surfaces will wear in quickly. Running-in Maintenance at 1,000 km ( 600 miles ) is designed to
compensate for this initial minor wear. Timely performance of the running-in maintenance will ensure
optimum service life and performance from the engine.
MAINTENANCE
•
•
When service is required, remember that your authorized Honda dealer knows your motorcycle
best and is fully equipped to maintain and repair it. The scheduled maintenance may also be
performed by a qualified service facility that normally does this kind of work; or you may
perform most of the work yourself it you are mechanically qualified and have the proper tools
and service data.
These instructions are based on the assumption that the motorcycle will be used exclusively for
its designed purpose. Sustained high speed operation, or operation in unusually wet or dusty
conditions, will require more frequent service than specified in the MAINTENANCE SCHEDULE.
Consult your authorized Honda dealer for recommendations applicable to you individual needs
and use.
MAINTENANCE SCHEDULE
The following items require some mechanical knowledge. Certain items ( particularly those marked*
and** ) may require more technical information and tools. Consult your authorized Honda Dealer.

6. Install the removed parts in the reverse order of disassembly.
ENGINE OIL
( Refer to the maintenance precaution. )
Engine Oil
Good engine oil has many desirable qualities. Use only high detergent, quality motor oil certified on the
container to meet or exceed requirements for service SE or SF. It is not necessary to use additives.
Viscosity:
Viscosity grade of engine oil should be based on average atmospheric temperature in your riding area.
The following provides a guide to the selection of the proper grade or viscosity of oil to be used at
various atmospheric temperatures.
Oil Change
Engine oil quality is the chief factor affecting engine service life. Change the engine oil as specified in
the maintenance schedule.
NOTE
Change engine oil with the engine at normal operating temperature and the
motorcycle in an upright position to assure complete and rapid draining.
1. Remove the oil filler cap/dipstick (1) and drain plug (2) to drain the oil.
WARNING
A warmed-up engine and the oil in it are hot; be careful not to burn
yourself.
2. With the ignition switch OFF, operate the kick starter several times to drain any oil which may be
left in the engine.
3. Check that the sealing washer on the drain plugs is in good condition and install the plug.
Replace the sealing washer every other time the oil is changed, or each time if necessary.
4. Fill the crankcase with the recommended grade oil; approximately:
0.9 L ( 1.0 US qt, 0.8 Imp qt ) .
5. Install the oil filler cap/dipstick.
6. Start the engine and let it idle for a 2-3 minutes.
7. Stop the engine and check that the oil level is at the upper level mark on the dipstick with the
motorcycle up light on firm, level ground. Make sure there are no oil leaks.
NOTE
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
service station for reclamation. Do not throw it in the rubbish or pour it on the
ground.
WARNING
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 possible after handling used oil.

•
The spark plug must be securely tightened. An improperly tightened plug
can become very hot and possibly damage the engine.
Never use a spark plug with an improper heat range. Sever engine
damage could result.
VALVE CLEARANCE
( Refer to the maintenance precaution. )
Excessive valve clearance will cause noise, and little or no clearance will prevent the valve from closing
and cause valve damage and power loss. Check valve clearance at the specified intervals.
CAUTION
1.
2.
3.
4.
Checking or adjusting of valve clearance should be performed while the engine
is cold. The clearance will change as the engine temperature rises.
Remove the crankshaft hole cap and timing mark hole cap.
Remove the valve adjuster covers.
Rotate the crankshaft counterclockwise and align the T mark (1) with the index mark (2). Make
sure the piston is at the top of the compression stroke by jiggling the rocker arms with your
fingers. If they are free, the piston is at the top of the compression stroke. If they are tight,
rotate the crankshaft 360‹ and re-align the marks.
Check the clearance by inserting the feeler gauge (3) between the valve adjusting screw (4) and
valve stem.
