Servicing Your Honda

General Competition Maintenance

Handgrips

Always use Pro Honda Handgrip Cement or
equivalent when replacing handgrips.

Throttle Grip

Align the index mark on the throttle grip with the
edge of the throttle cable guide.

Left Handlebar Grip

Align the “

” mark on the left handlebar grip with

the paint mark on the handlebar.
Refer to the Service Manual for installation
instructions.

For added security, you may choose to bind the
handgrips to the handlebar and throttle pipe with
safety wire to prevent the possibility of them
loosening. Position the twisted wire ends away from
your palms and be sure to bend the wire ends well
into the handgrip rubber so they will not snag your
glove.

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 affected by an air cleaner that has
deteriorated and allows dirt to pass. Inspect the 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 servicing 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. Pro Honda White
Lithium Grease, or an equivalent, is handy for this because
any dirt that penetrates this sealing area will show up clearly
(page 40).
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 does not have equivalent quality may cause
premature engine wear or performance problems.

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 36).

Air Cleaner Housing Sealing

Remove and reseal the air cleaner connecting boot where it
connects to the air cleaner housing with silicone sealer if
there is any doubt to its sealing integrity. Inspect the air
cleaner and air intake tract regularly for signs of
deterioration or dirt penetration.

Throttle Control

Remove the throttle control every few rides, clean the inside
of the throttle pipe and handlebar thoroughly, and apply a
light coating of silicone lubricant. Inspect the cable carefully
for kinks or other damage that may restrict throttle control in
any way. Move the handlebar from lock to lock to be sure
there is no cable interference. Check to be sure the top of
the carburetor is screwed on tight. Make certain the throttle
operation is perfect after servicing and inspecting.
