General Competition Maintenance
Handgrips
Always use Pro Honda Handgrip Cement when replacing
handgrips.
Refer to the Service Manual for installation
instructions.
Throttle Grip
Align the index mark on the throttle grip with the index mark
of the throttle cable guide. Left handlebar grip: Align the "∆"
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, and apply a
light coating of oil. 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 Removal
Put a little grease on the cylinder mounting dowels to
prevent corrosion from dissimilar metals. The tolerances are
quite tight, so it's important to keep these dowels absolutely
clean (page 67).
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 Pro Honda
Hondalock or an equivalent prior to torquing the nuts.
Fuel Filter
Periodically drain the fuel from the fuel tank, remove and
clean the fuel valve/filter. Replace the fuel valve O-ring if
there are any signs of damage or deterioration (page 35).
Fuel Contamination
Refer to Fuel System in your Owner's Manual, page 34.
Check the fuel lines for deterioration, damage, or leakage.
Replace the fuel lines, if necessary.
Periodically drain the fuel from the tank, remove and clean
the fuel valve and fuel filter. Replace the fuel valve O-ring if
there are any signs of damage or deterioration (page 35).
Loosen the carburetor drain screw and examine the fuel that
flows out of the float bowl. If you notice anything in the fuel,
such as water or dirt, remove the float bowl and inspect its
contents (page 119).
For maximum efficiency, drain and replace fuel that has
remained in your fuel tank for more than a month.
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 Pro Honda Dielectric Grease on all
electrical connections.
