A. Pass the high tension cord to the left of the
radiator hose.
B. No cable routing such as wire harness on the
push pin of the frame.
C. Clamp the CDI magneto lead and ignition coil
lead to the frame at its locating tape. After
tightening the clamp, cut off the end of the
clamp so that the remaining end is 1–5 mm
(0.04–0.20 in) in length. The tightening direc-
tion does not matter.
D. Clamp to the frame the ignition coil lead. After
tightening the clamp, cut off the end of the
clamp so that the remaining end is 1–5 mm
(0.04–0.20 in) in length. The tightening direc-
tion does not matter.
E. Clamp to the frame the throttle cable, clutch
cable, ignition coil lead and engine stop
switch lead. In so doing, clamp the ignition
coil lead and engine stop switch lead at their
protecting tubes.
Align the engine stop switch lead with the
positioning tape portion, and then clamp the
lead. The clamp position should be close to
the damper.
After tightening the clamp, cut off the end of
the clamp so that the remaining end is 1–5
mm (0.04–0.20 in) in length. The tightening
direction does not matter.
F. Clamp to the frame the throttle cable, clutch
cable and engine stop switch lead. In so
doing, clamp the engine stop switch lead at
its protecting tube. After tightening the clamp,
cut off the end of the clamp so that the
remaining end is 1–5 mm (0.04–0.20 in) in
length. The tightening direction does not mat-
ter.
G. Pass the radiator breather hose under the
clamp ends.
H. Face the CDI unit coupler projection outside
of the vehicle when installing the CDI unit.
I. Face the joint connector with its open end
downward, and there is no pinching with
peripheral parts. Joint connection position
does not matter.
CABLE ROUTING DIAGRAM
J. Pass the CDI magneto lead and radiator
breather hose between the frame and the
radiator (right).
K. Place the clamp end so that it is located out-
side the vehicle beyond the ignition coil lead.
L. After connecting the coupler, make sure that
the connector cover (throttle position sensor
lead/solenoid valve lead) contacts the end of
the coupler.
M. Clamp the wire harness with two white tapes.
N. Good
O. No good
P. Pass the throttle cable and clutch cable under
the frame (weld bead).
Place the clamp end so that it is located
under the clutch cable of the vehicle.
Q. Insert the CDI unit band until it stops at the
CDI unit stay.
R. Pass the throttle cable, clutch cable and
engine stop switch lead under the frame
(weld bead).
S. After connecting the couplers, move the han-
dlebar all the way to the right side and clamp
the leads without applying too much power.
T. Pass the CDI magneto lead and radiator
breather hose between the frame and the
radiator hose so that they come within the
arrow-indicated range. Also take care so that
the CDI magneto lead passes on the left of
the radiator breather hose.
