A. Pass the engine stop switch lead between the frame and the cable holder.
B. Insert the coupler for connecting optional part into the connector, and fix it to the bracket.
C. Insert and fix the engine stop switch coupler to the bracket.
D. Insert and fix the rectifie r/regulator coupler to the
bracket.
E. Pass the AC magneto lead to the front of the ve- hicle beyond the starter knob/idle screw and to
the rear of the vehicle beyond the radiator. No
pinch is allowed between the radiator and the
tension arm.
F. Make sure that there is no slack so that the starter motor lead cannot touch the end of the bolt.
G. Place the rear grommet of the starter motor lead matching the rear end of the side cover.
H. Insert the radiator fan motor fuse into the protru- sion of the holder plate.
I. Place the diode on top of the rear fender on the inner side of the rear frame.
J. Bring the neutral switch lead into line with the crankcase cover with no sag allowed.
K. Route the AC magneto lead inside the starter clutch cover.
L. Pass the neutral switch l ead to the inside of the
front engine bracket (the side of the vehicle).
M. Insert the plastic locking tie into the bracket hole and clamp the clutch cable. Clamp it so that the
lock of the plastic locking tie faces downward,
and then cut off the end of the plastic locking tie. N. Pass the clutch cable
with no downward sag al-
lowed.
O. Place the grommet of the clutch cable so that it contacts the radiator hose. Route the clutch cable
outside the neutral switch lead, AC magneto lead
and starter motor lead.
P. Route each lead so that the leads are not pinched
between the radiator hose and the frame.
Q. 40 mm (1.57 in)
R. Clamp the clutch cable, AC magneto lead, neu- tral switch lead and starter motor lead by the plas-
tic locking tie. Make sure that they are clamped at
the positioning tapes in the clutch cable and the
starter motor lead. Make the lock on the plastic
locking tie face the front of the vehicle, and cut
the end.
S. Clamp the starter motor lead to the inside of the tension arm with a plastic locking tie. Clamp it so
that the lock of the plastic locking tie faces up-
ward and outward, and do not cut off the end of
the plastic locking tie. R oute the lead so that there
is no slack at the bottom from the clamp position
onwards.
T. After connecting the neutral switch coupler, at- tach the coupler cover.
U. After connecting the crankshaft position sensor coupler, attach the coupler cover.
V. Pass the rectifier/regulator lead to the inside of the tension arm (the side of the vehicle).
W. Pass the main harness to the front of the radiator
hose (the front of the vehicle), and to the inside of
the clutch cable (the side of the vehicle).
X. Pass the engine stop switch lead between the coupler for connecting optional part and the tank
rail, with the lead on the main harness side facing
the top of the vehicle.
Y. Insert the starter motor lead completely into the end of the side cover 5.
Z. Clamp the clutch cable at the front of the lead (the
front of the vehicle).
AA.Insert the clip of the pl astic locking tie into the
frame. Face the lock of the plastic locking tie for-
ward, and then cut off the end.

A. Fix the wire harness, clutch switch lead and start switch lead by the plasti c clamp, and insert the
projection of the plastic clamp into the hole in the
sheet metal of the radiator.
B. Route each lead so that the leads are not pinched between the tank rail and air filter joint.
C. Insert the projection of the wire harness into the hole in the frame.
D. Pass the cylinder head breather hose between the throttle cable and engine ground sub-lead.
E. Insert the engine ground sub-lead coupler into the plate, facing inside the vehicle.
F. Connect the sub-wire harness to the wire har- ness.
G. Pass the high tension cord above the fuel hose.
H. ±10°
I. Install the spark plug cap with this facing the right
of the vehicle.
J. Push the spark plug cap home, where there shall be no gap between it and the cylinder head cover.
K. Pass the radiator breather hose between the down tubes.
L. Pass the starter motor lead under the starter mo- tor shaft.
M. Pass the sub-wire harness between the ECU and the air filter case.
N. Apply adhesive to the s lit and inside of the grom-
met, and then fix the grommet according to the
specified dimensions.
O. 50±3 mm (2.0±0.12 in)
P. Insert the coupler of the sub-wire harness into the
rib of the air filter case. Q. Clamp the starter motor lead, point the clamp
downward, and insert it into the frame.
R. Route the radiator breather hose through be- tween the radiator hose, down tube and engine
bracket.
