A. Clamp the clutch cable and right handlebar
switch lead to inside of the radiator stay
with the clamp aligning to their white tape
marks.
B. After connecting the main harness and
headlight sub-wire harness, insert them
into the rectifier/regulator bracket stay.
C. To the radiator
D. Route the coolant reservoir hose, main
harness and AC magneto lead in this order
from the top. Each of them can either be
right or left.
E. Route the ignition coil lead through the
heat protector hole and to right of the
engine.
F. Route the coolant reservoir hose in front of
the crankcase breather hose and to the
coolant reservoir tank. Route it as shown in
the illustration and it should not touch the
air bleed hose clip.
G. Route the main harness behind the crank-
case breather hose.
H. Route the starter motor lead and fuel pump
lead under the fuel tank breather hose and
fuel tank overflow hose, behind the fuel
hose and above the ground lead and bat-
tery negative lead.
I. Clamp at position of the starter motor lead
(white) and fuel pump branch lead (purple).
Do not cut the end and face the clamp to
the back.
J. Install with the ground lead at the bottom
and the battery negative lead on the top.
Install the rivet of the each lead facing up.
Angle of installing each lead is shown in
the illustration.
K. Route the canister purge hose under the
wire harness and air bleeding hose and
above the coolant reservoir hose.
L. Route the sidestand switch lead outside of
the installation dotted line at the back of the
coolant reservoir tank.
M. Connect the oil level switch lead, gear posi-
tion sensor lead, speed sensor lead and
sidestand switch lead (order insignificant)
and put the connector cover on.
N. To the AC magneto
O. To the coolant reservoir tank
P. The intake funnel servo motor lead can
either be on top or bottom of the branched
secondary injector sub-wire harness and
throttle sub-wire harness.
Q. To the throttle body
R. To the air filter case
S. To the intake funnel servo motor
T. Clamp the main switch lead, left handlebar
switch lead and steering damper lead
between the radiator stay and main har-
ness. Ratchet of the clamp can face in any
direction.
U. To the intake air temperature sensor and
headlight
V. Clamp the main switch lead, left handlebar
switch lead and steering damper lead to
inside of the radiator stay with the clamp
aligning to their white and blue tape marks.
W. End of the clamp should be at front and
facing down.
X. Clamp the coolant reservoir hose and
water pump bypass hose.
Y. Install the coolant reservoir hose with the
clamp opening facing up.
Z. Fit the connector cover including the oil
level switch lead, gear position sensor
lead, speed sensor lead and sidestand
switch lead (order insignificant) between
the thermostat bypass hose 2 and main
harness.
AA.Install the water pump bypass hose with its
clamp opening facing right of the vehicle.
AB.Clamp the secondary injector sub-wire
harness and throttle sub-wire harness at
the protector. Face the end of the clamp
downward.
