Handgrips: Always use Honda Hand Grip Cement
(U.S.A. only) or Honda Bond A when replacing
handgrips.
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.
Refer to the Service Manual for installation instruc-
tions.
•
Gaskets: Always use new gaskets when reassem-
bling components.
•
Cylinder Removal: Put a little grease on the cylin-
der mounting dowels to prevent corrosion from
dissimilar metals. The tolerances are quite tight, so
it's important to keep these dowels absolutely clean.
For added security, you may choose to safety wire
the hand grips to the handlebar and throttle to pre-
vent 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 grip rubber so
they will not snag your glove.
•
Throttle Control: Remove the throttle control every
few rides, clean the inside of the drum and the
handlebar thoroughly, and apply a light coating of
silicone lubricant. Inspect the cable carefully for
kinks or other damage that may restrict throttle con-
trol in anyway. 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.
•
Fuel Filter: Periodically drain the fuel from the tank,
remove and clean the fuel filter. Replace the fuel fil-
ter O-ring if there are any signs of damage or dete-
rioration. (page 48)
•
Fuel Contamination: Periodically drain the float bowl
and inspect the carburetor for contamination from
dirt. (page 62)
•
Engine Mounting Bolts: Make sure the engine
mounting bolts 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.
•
Electrical Connectors: Clean electrical connectors
and wrap them with electrical tape to reduce the
possibility of unwanted disconnections, water
shorts or corrosion. Additional corrosion protec-
tion is offered by using Honda Dielectric Grease on
all electrical connections.
