Servicing Your Honda
Start the engine, pull the clutch lever in,
and shif t into gear. Make sure the
engine does not stall and the motorcycle
does not creep. Gradually release the
clutch lever and open the throttle. Your
motorcycle should move smoothly and
accelerate gradually.
If you cannot get proper adjustment, or the
clutch does not work properly, the cable or
clutch friction discs may be worn. See
your Honda dealer or ref er to the of f icial
Honda Service Manual (page ).Lubricate the clutch cable with a
commercially-available cable lubricant
to prevent premature wear and
corrosion. Check the clutch cable for kinks or
signs of wear. If necessary, have it
replaced. Check that the clutch lever assembly is
positioned properly and the securing
bolts are tight. 5.

Saf ety Precautions The best way to assure proper carburetion
is to see your Honda dealer f or regularly
scheduled servicing, including individual
carburetor adjustment and synchronization. Ref er to on page .
Remember, idle speed adjustment is not a
‘‘cure-all’’ f or other problems in your
engine’s f uel-delivery system. Adjusting
the idle will not compensate f or a f ault
elsewhere.
The engine must be at normal operating
temperature for accurate idle speed
adjustment.
For inf ormation about high altitude
carburetor adjustment, see page . If the engine is cold, start it and warm it
up with ten minutes of stop-and-go
riding. Stop the engine.

Suspension
Servicing Your Honda
The way you ride your motorcycle and the
type of ride you want to experience can
also inf luence your suspension needs. Your f ront and rear suspension systems
use springs and hydraulic damping devices
that suspend your weight and most of the
weight of your motorcycle.
The spring pre-load f or your rear
suspension system adjusts the amount of
f orce required to begin compression of the
spring.
The oil damper systems hydraulically
control the natural compression and
rebound of the suspension springs so that
traction and comf ort are maintained as the
wheels ride over road surfaces.Lower spring pre-load provides a sof ter
ride and is usually pref erred f or light loads
and smooth roads. Higher spring pre-load
provides a f irmer ride and is
recommended f or heavy loads, rough road
conditions, and f aster, more challenging
riding. Consider adjusting your rear suspension
pre-load whenever you change your
normal load, by adding or subtracting a
passenger, cargo, or accessories, or when
the road or riding conditions change.
