SPARK PLUG
Your ATV is equipped with a DR8EA (NGK) spark plug. To determine if the standard
spark plug is in good condition, check the color of the plug’s center electrode insulator
after vehicle operation. A brown color indicates that the plug is correct. A white or dark
insulator indicates that the engine may need adjustment, or another plug type may be
needed. Consult your authorized dealer or Baja Motorsports if your plug insulator is not
a light brown color.
CAUTION
Failing to use the proper spark plug could damage your ATV.
An improper spark plug may have an incorrect fit or heat range for your engine. This
may cause severe engine damage which may not be covered under warranty.
Use only spark plug recommended for this engine. Call Baja Motorsports if you
are not sure which spark plus is correct for you vehicle.
CAUTION
Improper installation of the spark plug could damage your ATV.
An overly tight or cross threaded spark plug will damage the aluminum threads of
the cylinder head.
Carefully turn the spark plug by hand into the threads. If the spark plug is new,
tighten it with a wrench about 1⁄2 turn past finger tight. If you are reusing the old
spark plug, tighten it with a wrench about 1/8 turn past finger tight.
CAUTION
Dirt could damage your ATV if it entered an open spark plug hole of cylinder head.
Dirt could damage engine parts that move.
Cover the spark plug hole while the spark plug is out of the hole.
To maintain a proper functioning spark plug, keep the plug
free of carbon. Remove carbon from the plug with a wire
or pin, and adjust the gap to 0.6~0.7mm for good ignition.
Use a thickness gauge to check the gap.
