•
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 edge of the throttle cable guide.
Left handlebar grip: Align the "∆" mark on the left
handlebar grip with the punch mark on the handle-
bar.
Refer to the Service Manual for installation instruc-
tions.
For added security, you may choose to safety wire
the hand grips to the handlebar and throttle 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 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
control 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.
•
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.
•
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.
•
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.
•
Fuel Filter: Periodically drain the fuel from the tank,
remove and clean the fuel valve/filter. Replace the
fuel valve O-ring if there are any signs of damage or
deterioration. (page 36)
•
Fuel Contamination: Periodically drain the float
bowl and inspect the carburetor for contamination
from dirt. (page 48)
•
Inlet Tract Sealing: Air leaks around the carburetor
insulator and reed valve assembly should be cured
by disassembling, cleaning and resealing with new
gaskets and some sealing agent. Be careful not to
overtighten the mounting bolts—this is the most
common cause for leaks here.
•
Ignition: Remove the alternator cover and keep it
off for a few hours after each washing to let conden-
sation evaporate. Pull the flywheel rotor every few
rides and clean it and its crankshaft mounting sur-
face, the alternator stator, the ignition pulse gen-
erator pickup and the entire ignition cavity thor-
oughly. The presence of dirt between the ignition
pulse generator and the flywheel makes the igni-
tion control module compensate to maintain the
ignition curve. Cleaning dirt from the ignition side
main seal helps to prevent premature seal wear.
Close inspection of this seal can reveal a leakage
problem before engine damage occurs.
