A. Fasten the wire harness with the clamp on the
frame. Fasten the wire harness to avoid slack.
B. To the fuel tank
C. When routing the intake air temperature sensor
lead, make sure that it is not seized in the fuel
pump case box.
D. Place the sidestand switch coupler and two stator
coil assembly couplers in the coupler cover.
E. To battery terminal
F. Fasten the battery leads with the plastic locking
tie. Point the end forward.
G. Route the headlight relay (on/off) lead (white tape)
to the inside of the vehicle.
H. Route the fuel pump lead between the fuel pump
case and the fuel pump case box. Also, route the
fuel pump lead between the fuel pump case and
the fuel hose (fuel pump–fuel rail).
I. Fasten the sidestand switch lead and two stator
coil assembly leads to the external side of the
engine mount with the plastic locking tie. Point the
end forward and cut off an excess end.
J. Fasten the sidestand switch lead, two stator coil
assembly leads, and air filter case drain hose with
the clamp.
K. Avoid slack of the lead in this space.
L. Fasten the sidestand switch lead and rectifier/reg-
ulator lead to the external side of the engine mount
stay with the plastic locking tie. Point the end
upward and cut off an excess end.
M. Fasten the taped portion of the sidestand switch
lead and rectifier/regulator lead with the frame
clamp. Fasten the leads so that there is no slack.
N. To the engine
O. Fasten the breather hose and oil hose 2 with the
clamp.
P. Fasten the sidestand switch lead with the frame
clamp.
Q. Route the oil hose 2 below the tank rail.
R. Route the throttle position sensor lead above the
ISC (idle speed control) valve lead.
S. Pass the rear brake light switch lead through the
inside of the fuel pump case box flange.
T. Breather hose routing
U. Fasten the breather hose with the air filter case
holder.
V. Fasten the sidestand switch lead and two stator
coil assembly leads with the plastic locking tie.
Point the end downward.
W. Fasten the sidestand switch lead with the plastic
locking tie. Point the end to the inside of the vehi-
cle and cut off an excess end.
X. Fasten the sidestand switch lead and rectifier/reg-
ulator lead with the plastic locking tie. Point the
end to the inside of the vehicle and cut off an
excess end.
