A. Adjust slack in the handlebar switch lead
(left) and start switch lead at the vehicle’s
front side of the cable holder.
B. Pass the handlebar switch lead (left) and the
start switch lead between the frame and the
cable holder. Pass the handlebar switch lead
(left) above the start switch lead.
C. Insert the rectifier/regulator 2-pin coupler (not
colored) and rectifier/regulator 3-pin coupler
(not colored) into the bracket and secure
them. After securing, install the cover over
them.
D. Pass the rectifier/regulator lead (wire harness
side) to the inside of the tension arm (the side
of the vehicle).
E. Bring the protector of the clutch cable into
contact with the radiator hose, and pass it to
the outside of the gear position switch lead
and the stator coil assembly lead (the outside
of the vehicle).
F. Make sure that the stator coil assembly lead
does not get caught between the radiator and
the gear position switch 3-pin coupler (white).
G. Pass the stator coil assembly lead behind the
radiator. Be sure the lead will not be pinched
between the radiator and the tension arm.
H. After connecting the gear position switch 3-
pin coupler (white), attach the coupler cover.
I. After connecting the stator coil assembly 2-
pin coupler (gray), attach the coupler cover.
J. Fasten the clutch cable, gear position switch
lead, and stator coil assembly lead over the
grommet with the plastic locking tie. Point the
end of the plastic locking tie to the front side
of the vehicle, and then cut off it.
K. Pass the radiator breather hose through the
down tube.
L. When fastening the starter motor lead with
the clamp, close the clamp while applying
tension to the starter motor lead so that the
starter motor lead has no slack.
In addition, be careful so that the starter
motor lead does not contact the push lever
shaft. However, it does not matter if the
starter motor lead contacts the crankcase
bolt and timing chain tensioner.
M. Clamp the clutch cable at the front of the lead
(the front of the vehicle).
N. The routing order of the gear position switch
lead and stator coil assembly lead does not
matter.
O. Insert the clip portion of the clamp into the
frame. The lock part should face toward the
front of the vehicle.
Cut off the end of the remaining portion.
P. Diagram for routing the radiator hose and
radiator breather hose.
Q. When installing the dampers and the lower
handlebar holders in the front hole, be sure to
route the handlebar switch lead (left) as
shown in the illustration.
