SERVICE
The spark plug gap should be 0.040 inches. Make sure that the new spark plugs are the
same type as the ones being replaced: Champion
®
RA8HC. Spark plugs should be torqued
to 14 ft lbs. If the engine seems to be running on only one cylinder, check the spark plug
wire connection at both ends.
HEADLIGHT REPLACEMENT
The headlight has a replaceable quartz halogen
bulb. When replacing a halogen bulb never touch the glass portion with your bare fingers.
Oil contamination will reduce bulb life. Always wrap the bulb in clean paper or a clean dry
cloth during handling. Do not attempt to remove bulb while it is still hot.
TURN SIGNALS
The turn signals for this motorcycle are designed for brighter
illumination and longevity. Substitution with any other type or brand of turn signal will
disrupt the operation of the electrical system. For parts and service, contact a Big Dog
Motorcycles Dealer or Authorized Service Center.
