REMOVAL
1 Disconnect battery ground cable.
2 Loosen fuel filler cap.
3 Drain fuel.
After drain the fuel tighten the drain plug with
specified torque.
Torque : 20 Nꞏm (2.0 kgꞏm/14 lb ft)
4. Disconnect harness connector from fuel gauge unit.
5. Fuel Gauge Unit
1) Remove the fixing screws, then the fuel gauge
unit.
INSTALLATION
1. Fuel Gauge Unit
2 Connect the harness connector to the fuel gage
unit.
3 Fill the tank with fuel and tighten fuel filler cap.
4 Connect battery ground cable.
FUEL FILLER CAP
The fuel filler cap contains a vacuum valve. If a
negative pressure develops in the fuel tank, the
external valve of the fuel filler cap opens to allow the
fresh air to flow into the fuel tank through the vacuum
valve.
INSPECTION
Check the seal ring in the filler cap for presence of any
abnormality and for seal condition.
Replace the filler cap, if abnormal.Legend

2 Remove the slave cylinder and bind with wire it to
the frame.
3 Disconnect the connector from terminals “B” and
“S”.
4. Remove mounting bolts
5. Remove starter assembly
INSTALLATION
1. Install starter assembly, tighten the fixing bolt and
nut to the specified torque.
Torque: 94 Nꞏm (9.6 kgꞏm/69 lb ft)
2. Reconnect the starter terminals.
CAUTION: When installing the starter motor wiring,
do not allow the S-circuit wiring to obstruct the B-
circuit terminal.
Install the wiring exactly as shown on the attached
illustration.
If S-circuit wiring obstructs the B-circuit terminal,
harness cover breakage and short circuiting may
occur.2-1. Install the wire harness from the battery to the
terminal “B” with tightening torque 8.6 Nꞏm
(0.88 kgꞏm/6.4 lbꞏft).
2-2. Cover the terminal “B” together with wire
harness.
2-3. Connect the wire harness from starter relay to
the terminal “S”.
3. Install the clutch slave cylinder, tighten the fixing
bolt and nut to the specified torque.
