Suzuki GSX-R 1000 Service Manual: Spark plug inspection and cleaning
Inspect spark plug
every 6 000 km (4 000 miles, 12 months)
Heat range
- Remove the spark plugs. Refer to “ignition coil and spark plug removal
and installation” in section 1h .
- Check spark plug heat range by observing electrode
color. If the electrode of the spark plug is wet
appearing or dark color, replace the spark plug with
hotter type one. If it is white or glazed appearing,
replace the spark plug with colder type one.

- After finishing the spark plug inspection, reinstall the
removed parts.
Tightening torque
Spark plug gap
spark plug: 11 n·m (1.1 Kgf-m, 8.0 Lbf-ft)
- Remove the spark plugs. Refer to “ignition coil and spark plug removal
and installation” in section 1h .
- Measure the spark plug gap using a wire gauge. If it
is not within the specification, replace the spark plug.
Caution
- To prevent the damage of iridium center
electrode, use a wire gauge to check the
gap.
- Never adjust the spark plug gap.

- After finishing the spark plug inspection, reinstall the
removed parts.
Tightening torque
spark plug: 11 n·m (1.1 Kgf-m, 8.0 Lbf-ft)
Electrodes condition
- Remove the spark plugs. Refer to “ignition coil and spark plug removal
and installation” in section 1h .
- Check the worn or burnt condition of the electrodes.
If it is extremely worn or burnt, replace the spark
plug. And also replace the spark plug if it has a
broken insulator, or damaged thread.
Caution
confirm the thread size and reach when
replacing the plug. If the reach is too short,
carbon will be deposited on the screw
portion of the plug hole and engine damage
may result. |
- After finishing the spark plug inspection, reinstall the
removed parts.
