CABLE ROUTINGSPEC
I The coupler for the air induction
solenoid lead and camshaft sen-
sor lead should be connected
above the ignition coil sub wire
harness and it should not drop
on the cylinder head cover be-
hind the ignition coil.
J Pass the right handlebar switch
lead between the frame and heat
protector.
K Coolant reservoir tank drain
hose should cross with the
speed sensor lead under the
swingarm bracket. Route the
coolant reservoir tank drain hose
over the up side of the vehicle.L Pass the rear brake light switch
lead between the swingarm
bracket and coolant reservoir
tank.
M Release the tip of the clamp and
install it to the clutch cable.
Insert the clamp to the hole lo-
cated on the right back side of
the radiator.
Radiator fan motor lead should
not be caught while inserting the
clamp.
N Push the clamp until it hits the ra-
diator side stay. Radiator fan mo-
tor lead should not be caught.

D To the EXUP servo motor
E Pass the coolant reservoir tank
drain hose and fuel tank drain
hose through the clamp from the
outer side of the water pump inlet
pipe after routing it behind the
water pump breather hose.
The lengths of two hose ends are
allowed to be random. Any direc-
tion of cut edges can be ac-
cepted. (Only for the fuel tank
drain hose)
F Clamp the fuel tank drain hose
and fuel tank breather hose.A Clamp the leads so that they are
positioned inner of the vehicle
than the washer position after
routing them between the frame
and radiator stay. Align the clamp
position with the taping sections
of leads. Point the tip of the clamp
(surplus section) to the down
front side of the vehicle.
What the clamp fastens at this
stage are the handlebar switch
and main switch leads.
B Pass the main switch lead and
left handlebar switch lead be-
tween the frame and the heat
protector.

Air filter
This model’s air filter is equipped with a disposable oil-coated paper element, which must not be
cleaned with compressed air to avoid damaging it.
The air filter element needs to be replaced more frequently when riding in unusually wet or dusty areas.
Hydraulic brake service
After disassembling the brake master cylinders and calipers, always change the fluid. Regularly
check the brake fluid levels and fill the reservoirs as required.
Every two years replace the internal components of the brake master cylinders and calipers, and
change the brake fluid.
Replace the brake hoses every four years and if cracked or damaged.

ADJUSTING THE VALVE CLEARANCE
The following procedure applies to all of the
valves.
Valve clearance adjustment should be made
on a cold engine, at room temperature.
When the valve clearance is to be measured or
adjusted, the piston must be at top dead center
(TDC) on the compression stroke.
1. Remove

Refer to “SEATS”.
fuel tank
Refer to “FUEL TANK”.
air filter case
Refer to “AIR FILTER CASE”.

NOTE:
c. Round off the original valve pad number ac-
cording to the following table.

EXAMPLE:
Original valve pad number
= 148 (thickness =1.48 mm (0.058 in))
Rounded value = 150
d. Locate the rounded number of the original
valve pad and the measured valve clearance
in the valve pad selection table. The point
where the column and row intersect is the
new valve pad number.
The new valve pad number is only an approxi-
mation. The valve clearance must be measured
again and the above steps should be repeated if
the measurement is still incorrect.
e. Install the new valve pad
1 and the valve lift-
er
2.
Lubricate the valve pad with molybdenum dis-
ulfide grease.
Lubricate the valve lifter with molybdenum dis-
ulfide oil.
The valve lifter must turn smoothly when ro-
tated by hand.
Install the valve lifter and the valve pad in the
correct place.
f. Install the exhaust and intake camshafts,
timing chain and camshaft caps.
