Spark Plug: Testing and Inspection

1. REMOVE NO.2 PCV HOSE.
2. REMOVE AIR CLEANER HOSE.
3. DISCONNECT THROTTLE CABLE.
4. REMOVE NO.2 AND NO.3 CYLINDER HEAD COVERS.





- Remove the 4 bolts and head covers.
5. DISCONNECT HIGH-TENSION CORDS FROM SPARK PLUGS.





- Remove the 2 mounting bolts of the No.1 and No.2 cord clamps.





- Disconnect the high - tension cords at the rubber boot.
- DO NOT pull on the cords.

NOTICE: Pulling on or bonding the cords may damage the conductor inside.

6. REMOVE SPARK PLUGS.
- Using a 16 mm plug wrench, remove the spark plug.
7. CLEAN SPARK PLUGS.
- Using a spark plug cleaner or wire brush, clean the spark plug.
8. VISUALLY INSPECT SPARK PLUGS.
- Check the spark plug for electrode wear, threads damage and insulator damage.
- If abnormal, replace the plugs.

Recommended spark plugs: ND: KI6R-U NGK: BKR5EYA

9. ADJUST ELECTRODE GAP.
- Carefully bend the outer electrode to obtain the correct electrode gap.

Correct electrode gap: 0.8 mm (0.031 in)

10. INSTALL SPARK PLUGS.
- Using a 16 mm plug wrench, install the spark plug.

Torque: 20 Nm (14 ft lb)
