A. Fasten the clutch cable, right handlebar
switch lead and hazard 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 crankshaft position sensor 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. Fasten the main harness and fuel hose
between the breather hose and the main
harness (such as the ground lead). Route
the fuel hose on the side of the main har-
ness facing toward rear of the vehicle.
H. Route the main harness behind the crank-
case breather hose.
I. Fasten the starter motor lead and fuel
pump lead at the right of the vehicle. Do
not cut off the end and face it to back of the
vehicle.
J. Route the starter motor lead below the fuel
tank breather hose and fuel tank overflow
hose, back of the fuel hose and above the
ground lead and battery negative lead.
K. 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.
L. Route the fuel pump lead through front of
the fuel tank breather hose.
M. Route the sidestand switch lead outside of
the installation dotted line at the back of the
coolant reservoir tank.
N. Connect the oil level switch lead, gear posi-
tion sensor lead, rear speed sensor lead
and sidestand switch lead (order insignifi-
cant) and put the connector cover on.
O. To the AC magneto
P. To the coolant reservoir tank
Q. 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.
R. To the throttle body
S. To the air filter case
T. To the intake funnel servo motor
U. Fasten the front speed sensor lead, left
handlebar switch lead and main harness
within the range shown in the illustration
(between the ECU (engine control unit)
bracket rib and radiator core).
V. Route the left handlebar switch lead and
front speed sensor lead along the main
harness, making sure there is no slack in
the leads.
W. Align the main switch lead (white), left han-
dlebar switch lead (at the positioning tape)
and steering damper lead (white) to the
tapes and clamp them inside of the radiator
stay.
X. End of the clamp should be at front and
facing down.
Y. Route the hazard switch lead on the side of
the clutch cable facing toward front of the
vehicle.
