General Competition Maintenance
Handgrips
Always use Hand Grip Cement when replacing handgrips.
Refer to an official Honda Shop Manual for installation
instructions.
Throttle Grip
Right throttle grip: Align the index mark on the throttle grip
with the index mark of the throttle pipe.
Left handlebar grip: Align the index mark on the left
handlebar grip with the paint mark on the handlebar.
For added security, you may choose to bind the hand grips to
the handlebar and throttle pipe with safety wires 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.
Throttle Control
Remove the throttle control every few rides, clean the inside
of the throttle pipe and handlebar thoroughly. Inspect the cable
carefully for kinks or other damage that may restrict throttle
control in anyway. Move the handlebar from lock to lock to be
sure there is no cable interference. Make certain the throttle
operation is perfect after servicing and inspecting.

Servicing Your Honda
Gaskets
Always use new gaskets when reassembling components.
Cylinder head/Cylinder
Put a little grease on the dowel pins of the cylinder head and
cylinder to prevent corrosion from dissimilar metals. The
tolerances are quite tight, so it's important to keep these
dowels absolutely clean (pages 81, 83).
Engine Mounting Bolts and Nuts
Make sure the engine mounting bolts and nuts are tightened to the proper torque
specification. For added peace of mind, remove the nuts, clean the threads, and
apply Honda Thread Lock or an equivalent prior to torquing the nuts.
Fuel Line
Refer to Fuel System in your Owner's Manual, page 44.
Check the fuel line for deterioration, damage, or leakage.
Replace the fuel line every year.
Electrical Connectors
Clean electrical connectors and wrap them with electrical tape
to reduce the possibility of unwanted disconnections, water
shorts or corrosion. Additional corrosion protection is offered
by using Honda Dielectric Grease on all electrical
connections.
