4. SERVICE AND MAINTENANCE

GENERAL MAINTENANCE

•
Spark Plug: Some non-resistor plugs may cause
ignition problems. Refer to the recommendations
elsewhere in this manual for specific types so you
will be sure to use the proper reach and heat range.
Replace periodically as specified in the Mainte-
nance Schedule. (pages 11, 22)
•
Spark Plug Cap: Install a small plastic tie-wrap
around the spark plug cap to reduce any possibility
of it loosening or of water penetration.

•
Transmission Oil: Drain and replace transmission
oil often to ensure the greatest service life of the
transmission and clutch. Frequent changes will
also assure consistent performance of both shifting
and clutch action. (page 20)
•
Air Cleaner: Clean and oil your air cleaner regularly
because the volume of air able to pass through it
has a great effect on performance. Both engine
performance and long term durability may be af-
fected by an air cleaner that has deteriorated and
allows dirt to pass. Inspect the air cleaner closely
each time it's serviced for evidence of small tears or
seam separation. Keep a spare air cleaner oiled and
ready to install, sealed in a plastic bag. Riding in
dusty conditions may require servicing the air
cleaner or replacing it with a pre-serviced air cleaner
between motos. Be careful not to over oil the air
cleaner. While it is important to oil the air cleaner
thoroughly, over oiling will cause an overall rich
running condition, probably more noticeable off
idle and in low rpm performance. Follow the serv-
icing instructions in the Maintenance section. Use
Pro Honda Foam Filter Oil or an equivalent. Be sure
to grease the air cleaner flange where it contacts the
air cleaner housing. Honda White Lithium Grease,
or an equivalent, is handy for this because any dirt
that penetrates this sealing area will show up clearly.
(page 23)
Use the Honda genuine air cleaner or an equivalent
air cleaner specified for your model.
Using the wrong Honda air cleaner or a non-Honda
air cleaner which is not of equivalent quality may
cause premature engine wear or performance prob-
lems.
•
Air Box Sealing: Inspect the air cleaner and air
intake tract regularly for signs of deterioration or
dirt penetration.
When removing or resealing the air cleaner hous-
ing boot you need to replace the air cleaner housing
boot gasket with a new one.
Refer to the official Honda Service Manual (page 84)
for removal, installation and reseal of the air cleaner
housing boot.
