19. Shift sensor coupler (white)
20. Crankshaft position sensor coupler
21. Stator coil coupler
22. Thermostat assembly
23. Shift sensor lead
24. Thermostat assembly
25. Stator coil lead
A. To secondary injector
B. Route the starter motor lead under the engine
ground lead.
C. Route the gear position sensor lead to the inside of
the starter motor lead.
D. Route the fuel tank drain hose and fuel tank
breather hose (except for California) over the boss
for the shift shaft of the crankcase.
E. Route the fuel tank drain hose through the guide of
the cover and position it in front of the fuel tank
breather hose. Align the paint mark on the fuel tank
drain hose to the guide area of the cover. (except
for California)
F. Match the length of the fuel tank breather hose
coming out of the guide to the length of the fuel
tank drain hose. (except for California)
G. Position the cable holder below the oil level check
window.
H. Insert the plastic locking tie into the frame hole.
The position of the plastic locking tie may change
after installation; however, make sure that it does
not come off.
I. Fasten the wire harness with the plastic locking tie.
Face the buckle of the plastic locking tie upward,
and then cut off the excess end of the tie to 5 mm
(0.2 in) or less.
J. Fasten the sidestand switch lead, O
2
sensor lead
(left), and oil pressure switch lead with the holder.
Position the holder between the coupler cover and
the drive sprocket cover. The catch of the holder
may be facing in any direction.
K. The leads may be routed in any order.
L. Except for California.
M. For California.
N. Fasten the sidestand switch lead, O
2
sensor lead
(left), and oil pressure switch lead with the holder.
The catch of the holder may be facing in any
direction.
O. Make sure that the grommet does not protrude
from the sidestand switch cover. Face the slit in the
grommet inward. Make sure that the projection on
the sidestand switch cover is hooked onto the
groove in the grommet. Align the grommet with the
paint mark on the fuel tank drain hose.
P. Place the coupler cover behind the coupler cover
(stator coil side) and push it inside the projection
on the chain case cover.
Q. Position the coupler cover (stator coil coupler,
crankshaft position sensor coupler) to the inside of
the thermostat assembly as shown in the
illustration.
R. Route the shift sensor lead outside the fuel tank
drain hose and fuel tank breather hose (except for
California).
S. Fasten the stator coil lead and the shift sensor lead
to the thermostat assembly at the positioning tape
on the shift sensor lead with a plastic locking tie.
Position the plastic locking tie to the inside of the
protruding portion on the thermostat assembly.
Point the end of the plastic locking tie rearward and
upward. Do not cut off the excess end of the plastic
locking tie.
T. Route the shift sensor lead between the protruding
portions on the thermostat assembly.
