1. First, tighten the ring nut to approximately 52 Nm (5.2 m
kg, 38 ft
lb) with a torque wrench, then
loosen the ring nut completely.
2. Retighten the lower ring nut to specification.
Refer to “INSTALLING THE ENGINE” in chapter 5.
1. Insert the front wheel axle from the right side
and tighten it with the flange bolt from the left
side to 91 Nm (9.1 m
kg, 65.8 ft
lb).
2. In the order from the pinch bolt

pinch bolt 2, tighten each bolt to
20 Nm (2.0 m
kg, 14 ft

ing temporary tightening.
3. Check that the end face of the axle head and
the end face of the fork side are flush-
mounted. If they are out of alignment, make
sure to fit them by adding the external force
by hand or with a plastic hammer, etc.
If the end face of the axle is not parallel to the
end face of the fork, align them so that one
point of the axle circumference is positioned
on the end face of the fork.
At this stage, it can be accepted if the end
face of the axle becomes partially concave
to the end face of the fork.

E Clamp the clamp upper end
along the line of lower end of the
hose clamp assembly. Point the
tip of the clamp (surplus section)
to the front side of the vehicle.
Clutch cable is what the clamp
fastens.

H Clamp behind the bracket 3.17Throttle body lead
A Clamp it after passing between
the frame and radiator stay.
Point the tip of the clamp (exces-
sive part) to the front side of the
vehicle. Fasten the right handle-
bar switch lead with a clamp.
B To the wire harness

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.

K Pass the water hose lower side
of the thermostat, and between
the ground lead and the neutral
switch.
L Install the leads so that the en-
gine ground lead is positioned
lower and the battery negative
lead to be upper. Install the pro-
trusion of each lead to be above
the vehicle.
M Route the crankshaft position
sensor lead under the wire har-
ness.
N To the fuel pump
O Clamp the wire harness winding
in and insert it to the frame hole.A Pass the wire harness through
the clamp inserted to the radiator
stay.
B To the headlight lead
C Clamp the lead between three
protrusions of the pipe (the first
and second parts from the ve-
hicle front). Point the tip of the
clamp (excessive part) to the in-
side of the vehicle.
D To the vehicle right side diagram
E To the engine
F Clamp the lead between three
protrusions of the pipe (the in-
side and outside of the vehicle).G Point the tip of the clamp (exces-
sive part) to the inside of the ve-
hicle.
H All hoses and leads should be
routed over the vehicle’s upper
side above the heat protector.
I To the starter motor
J Fasten the wire harness, clank
shaft position sensor lead, rear
brake light switch lead and
speed sensor lead with a clamp.
Then, point the tip of the clamp
(cut the tip of the clamp leaving 2
to 4 mm (0.08 to 0.16 in).) to the
inside of the vehicle.
