2. Check spark plug gap against table specifications.
3. Always tighten to the proper torque. Spark plugs must be tightened to the torque specified
for proper heat transfer.
NOTE:
If a torque wrench is not available, tighten plugs finger tight and then tighten an additional one
quarter turn with a spark plug wrench.
Ignition
The engine in your motorcycle has been designed specifically to achieve optimum fuel economy
within exhaust emission controls. Factory programmed ignition characteristics provide maximum
engine performance and driveability.
NOTE:
The ignition control unit monitors engine load. In certain transient load conditions (as the throttle is
opened), the timing changes from normal to fully advanced. At this point, the operator can
sometimes hear a noise that is similar to pre ignition detonation.
This noise should not be confused with detonation which can be stopped by the use of a higher
grade fuel. It is caused by the instant pressure rise in the combustion chambers as the spark
advances rapidly. This noise doesn't affect engine performance.
Carburetor
The carburetor has been specifically designed for emissions control operation. All jets are fixed at
the factory.
Carburetor controls include throttle, enrichener and idle speed adjusting screw. Operation should
be checked and adjusted at proper intervals. Refer to Regular Service Intervals: 2005 Softail
Models.
Operation at higher altitudes (approximately 4000 ft. (1200
meters) elevation) can require carburetor modifications for
best engine performance. See a Harley Davidson dealer for
these adjustments. Failure to do so could result in
equipment damage. (00206a)
We recommend that any carburetor service be performed by a Harley Davidson dealer.
Air Cleaner
See Air Cleaner: Twin Cam Models. The engine air cleaner is a paper/wire mesh air filter
element.
Refer to Regular Service Intervals: 2005 Softail Models. Remove air cleaner cover and
inspect filter element at proper intervals. Under dusty conditions, inspect more often.
