Electrical System / Ignition System / Spark Plug Condition Inspection

  • Remove the spark plugs (see Spark Plug Replacement).
  • Visually inspect the spark plugs.

    If the spark plug center electrode [A] and/or side electrode [B] are corroded or damaged, or if the insulator [C] is cracked, replace the plug.

    If the spark plug is dirtied or the carbon is accumulated, replace the spark plug.

  • Measure the gap [D] with a wire-type thickness gauge.

    If the gap is incorrect, replace the spark plug.

    Spark Plug Gap: 0.8 - 0.9 mm (0.031 - 0.035 in.)

  • Use the standard spark plug or its equivalent.

    Spark Plug: NGK CR9EIA-9

Ignition System

Interlock Operation Inspection

  • Raise the rear wheel off the ground with stand.
  • Turn the engine stop switch ON (run position).

1st Check

  • Start the engine to the following conditions.

Condition:
 Transmission Gear → 1st Position
 Clutch Lever → Release
 Sidestand → Down or Up

  • Turn the ignition switch ON and push the starter button.
  • Then the starter motor should not turn when the starter system circuit is normality.

If the engine is start, inspect the starter lockout switch, sidestand switch, neutral switch and relay box.

2nd Check

  • Start the engine to the following conditions.

Condition:
 Transmission Gear → 1st Position
 Clutch Lever → Pulled in
 Sidestand → Up

  • Turn the ignition switch ON and push the starter button.
  • Then the starter motor should turn when the starter system circuit is normality.

If the starter motor is not turn, inspect the starter lockout switch, sidestand switch, relay box, and starter relay.

3rd Check

  • Inspect the engine for its secure stop after the following operations are completed.
  • Run the engine to the following conditions.

Condition:
 Transmission Gear → 1st Position
 Clutch Lever → Pulled in
 Sidestand → Up

  • Set the sidestand on the ground, then the engine will stop.

    If the engine does not stop, inspect the neutral switch, sidestand switch and relay box.

    If their parts are normality, replace the ECU.

IC Igniter Inspection

  • The IC igniter is built in the ECU [A].
  • Refer to the following items.
