Changing the Spark Plugs
Recommended spark plugs: E5RTC
In order to ensure that the engine operates normally, your spark plug needs a correct distance between
the center and side electrodes, and no carbon buildup. Follow these steps to ensure your spark plugs
are in good shape.
1.
Remove the spark plug maintenance cover.
2.
Take off the spark plug cap.
3.
Remove the spark plug using a spark plug spanner.
4.
Visually inspect the spark plug. If the insulator is cracked or chipped, replace it with a new one. If
there is buildup on the plug, clean it with a wire brush (if you are reusing it).
5.
Measure the spark plug gap between the center and side electrodes using a feeler gauge. The
normal value should be 0.028-0.031” (0.7-0.8 mm).
