INSPECTION AND MAINTENANCE

TOOLS

A tool kit is provided with your ATV.

SPARK PLUG

Your ATV is equipped with a T1136 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 INC. 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 the spark plug recommended for this engine. Call BAJA INC. if
you are not sure which spark plug is correct for you vehicle.
