P To the air filter
Q Route the fuel tank drain hose
over the canister stay and be-
tween the breather hose 2 and
wire harness. On the front side of
the canister stay, let though the
bottom of the A.C.magneto lead
and the wire harness.
R Route by the upside of vehicle
away from the canister stay.
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.
O Clamp the clutch cable so that it
is within this specified clamp.

C Fold back the clamp and secure
it after passing the lead through
the clamp.
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.

R Arrange so as not for each hose
to cross in the part between “BB”
from the section “AA” which is in
the illustration.G Route the lead by the inside of
the water hose and water pipe.
H Route the lead by the inside of
the water hose and water pipe.
I Route by the outside of vehicle
away from the water hose.
J Point the tip of the clamp (exces-
sive part) to the down rear side of
the vehicle. Fasten the wire har-
ness with a clamp.
K Route the water hose so that it is
placed at the outermost position
finally after routing other leads
and hoses in the guide.
L To the coolant reservoir tank
CABLE ROUTINGSPEC
M There should be no exposure of
bared conductors due to the dis-
placement of the tube.
N Route the coolant reservoir tank
drain hose so that it is routed at
the innermost position to each
hose and lead.
O Can be routed in any order.
P Align the molded part of the fuel
tank drain hose with the stay 1.
Q Routing of the fuel tank drain
hose.
EXUP servo motor, oil level
switch and sidestand switch
leads are omitted in this drawing.

CHECKING THE COOLANT LEVELCHK
ADJ
NOTE:
CAUTION:
NOTE: 7. Install:

bottom cowlings
Refer to “COWLINGS”.
EAS00102
CHECKING THE COOLANT LEVEL
1. Stand the motorcycle on a level surface.

Place the motorcycle on a suitable stand.

Make sure the motorcycle is upright.
2. Check:

coolant level
The coolant level should be between the
maximum level mark
a and minimum level
mark
b.
Below the minimum level mark
Add the
recommended coolant to the proper level.

Adding water instead of coolant lowers the
antifreeze content of the coolant. If water is
used instead of coolant check, and if nec-
essary, correct the antifreeze concentra-
tion of the coolant.

Use only distilled water. However, if dis-
tilled water is not available, soft water may
be used.
3. Start the engine, warm it up for several min-
utes, and then turn it off.
4. Check:

coolant level
Before checking the coolant level, wait a few
minutes until it settles.

CHANGING THE COOLANT
1. Remove:

side cowlings
Refer to “COWLINGS”.

rider seat
Refer to “SEATS”.
2. Remove:

coolant reservoir tank

coolant reservoir hose
3. Disconnect:

coolant reservoir cap

4. Drain:

coolant
(from the coolant reservoir tank)
5. Remove:

radiator cap
1
A hot radiator is under pressure. Therefore,
do not remove the radiator cap when the en-
gine is hot. Scalding hot fluid and steam may
be blown out, which could cause serious in-
jury. When the engine has cooled, open the
radiator cap as follows:
Place a thick rag or a towel over the radiator
cap and slowly turn the radiator cap coun-
terclockwise toward the detent to allow any
residual pressure to escape. When the his-
sing sound has stopped, press down on the
radiator cap and turn it counterclockwise to
remove.
The following procedure applies to all of the
coolant drain bolts and copper washers.
6. Remove:

Handling notes for coolant
Coolant is potentially harmful and should be
handled with special care.

If coolant splashes in your eyes, thorough-
ly wash them with water and consult a doc-
tor.

If coolant splashes on your clothes, quick-
ly wash it away with water and then with
soap and water.

If coolant is swallowed, induce vomiting
and get immediate medical attention.
