A. Align the throttle cable locating tape with the
cable guide. Fasten each part with the plastic
locking tie.
B. From the outside of the vehicle, pass the
engine stop switch lead, clutch cable and
throttle cable.
C. Insert the fuel tank breather hose end into the
steering shaft hole.
D. Pass the throttle cable, clutch cable and
engine stop switch lead above the radiator
hose.
E. Install the ignition coil and side core together
to the frame.
F. Clamp the throttle cable, high tension cord
and sub-lead wire (throttle position sensor
lead/solenoid valve lead) to the frame. Posi-
tion the lock portion under the frame. 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.
G. Make sure the high tension cord does not
contact with clutch cable. (It does not matter
if the clutch cable contacts with the grom-
met.)
H. Clamp the clutch cable and sub-lead wire
(throttle position sensor lead/solenoid valve
lead) to the engine bracket (left). The lock
portion should face the inner side of the vehi-
cle, while the end should face the rear side of
the vehicle. Make sure the connector cover
does not contact with engine. Do not cut the
end of the clamp.
I. Pass the air vent hose front of the throttle
cable.
J. Pass the air vent hose, overflow hose and
crankcase breather hose between the frame

breather hose and YPVS breather hose to
the frame. Do not cut the end of the clamp.
Pay attention so that the YPVS breather hose
is not crushed when installing the clamp.
M. Clamp the CDI magneto lead and radiator
breather hose to the rear side of the frame.
Pay attention so that the radiator breather
hose is not crushed when installing the
clamp. Position the end of the clamp inside
the YPVS breather hose. Take care to clamp
them above the projection on the frame. Do
not cut the end of the clamp.
N. Do not clamp throttle cable and clutch cable.
O. Locate the clamp ends in the arrowed range.

Q. Pass the throttle cable back of the air vent
hose.
R. The position of the air vent hose (right) and
overflow hose does not matter after passing
the clamp.
S. Pass the air vent hoses, overflow hose and
crankcase breather hose so that they do not
contact the rear shock absorber.
T. Position the clip as shown in the illustration.
Locate the clip in the arrowed range.
U. After connecting the coupler, make sure that
the connector cover contacts the end of the
coupler.
