SERVICE
FRONT FORK OIL
Drain and refill the front forks every 5,000 miles or annually. All
2006 models use 10 oz. of 30W synthetic fork oil. Improper fluid level or leaking seals will
cause the front forks to malfunction. If the fork does not appear to be working properly
or evidence of oil leakage should develop, see a Big Dog Motorcycles Dealer or Authorized
Service Center.
LUBRICATION
1. Lubricate throttle control cables with graphite every 2,500 miles.
2. Check steering head bearings for adjustment and lubricate with wheel bearing grease
at 500 miles and every 10,000 miles thereafter.
3. Lubricate the side stand with anti-seize every 2,500 miles.
4. All control pivot points may be lubricated regularly, especially after driving in wet
weather or after washing.
DRIVE BELT INSPECTION
The rear drive belt tension is set at the factory and
should be checked along with pulley wear at the 500-mile service and each 2,500 miles
thereafter. Inspect the belt for signs of excessive wear, tears, cracks and missing or broken
teeth. Replace the belt if any of these conditions are found. The inner tooth surface area
of a new belt is coated with a thin layer of polyethylene. This coating will wear off as the
motorcycle is ridden and its appearance will change. This is a normal condition and not
an indication of belt wear. Too tight or too loose belt tension will cause poor drivability.
