A. After connecting the fuel pump coupler, attach the coupler cover.
B. Pass the fuel hose to the front of the battery.
C. Route the resistor lead to the outside of the leads.
D. Connect the battery positive lead to the starter re- lay terminal (in the left side of the vehicle).
E. Insert the protruding end of the wire harness into
the battery bracket hole and holder plate hole.
F. After connecting the negative lead coupler, place it on the right side of the battery.
G. Route the diode under the cross member and place it on top of the rear fender.
H. Secure the two ends of the taillight coupler with the starter motor lead.
I. Route the taillight lead so that it does not slack at
the rear of the vehicle.
J. Clamp the taillight lead and insert the clip into the rear fender. Clamp it so that the lock faces in-
ward, and then cut off the excess end.
K. Lower end of the rear frame
L. Clamp it so that the lock of the plastic locking tie
faces downward, insert the end into the rear
frame and side cover 6, and then cut off the ex-
cess end. After cutting off the excess end, make
sure that the plastic locki ng tie does not protrude
from the lower end of the rear frame.
M. Clamp it so that the lock of the plastic locking tie
faces downward, and then pass the end between
the fuel hose and rear frame.
N. Clamp the wire harness at the position of the white tape.
O. Route the battery positive lead under the cross member.
P. After connecting the battery positive lead in the direction indicated in the illustration, put the cover
on.

TIP
• The air filter needs more frequent service if you are riding in unusually wet or dusty areas.
• Hydraulic brake service• After disassembling the brake master cylinders and calipers, always change the fluid. Regularly check the brake fluid levels and f ill the reservoirs as required.
• Every two years replace the internal components of the brake master cylinders and calipers, and
change the brake fluid.
• Replace the brake hoses every four years and if cracked or damaged.

3. Air scoop (left/right)
4. Fuel tank
5. Air filter case cover1. Check the fuse. Refer to “CHECKING THE FUSES”
on page 9-68. NG
Replace the fuse(s).
OK
2. Check the battery. Refer to “CHECKING AND
CHARGING THE BATTERY” on
page 9-69. NG
• Clean the battery terminals.
• Recharge or replace the battery.
OK
3. Check the spark plug. Refer to “CHECKING THE SPARK
PLUG” on page 3-40. NG
Re-gap or replace the spark plug.
OK
4. Check the ignition spark gap. Refer to “CHECKING THE IGNI-
TION SPARK GAP” on page 9-73. OK
The ignition system is normal.
NG
5. Check the ignition coil. Refer to “CHECKING THE IGNI-
TION COIL” on page 9-74. NG
Replace the ignition coil.
OK
6. Check the crankshaft position sen- sor.
Refer to “CHECKING THE CRANK-
SHAFT POSITION SENSOR” on
page 9-74. NG
Replace the stator assembly.
