1. Remove air cleaner cover.
2. Remove element.
3. Reinstall new carbon element on air cleaner back plate.
4. Reinstall air cleaner cover.
HYDRAULIC LIFTERS
Hydraulic lifters are self-adjusting. They automatically adjust
length to compensate for engine expansion and valve train wear,
keeping the valve train free of lash while the engine is running.
When starting the engine, the valve train may be noisy until
the lifters refill with oil. If the valve train remains noisy after
twenty minutes of operation, this may be an indication that one
or more of the lifters is not functioning properly. Then, if
necessary, remove and clean the hydraulic lifter oil filter screen.
Consult an S&S service agent if further service is required.
SPARK PLUGS
Spark Plug Removal:
1. Disconnect spark plug wires from spark plugs by
pulling on the molded connector boots. It may help
to twist or rock the boots back and forth slightly while
pulling.
2. Unscrew spark plugs.
Spark Plug Inspection:
If either of the following conditions occurs, further service is
required.
1. A spark plug with a black, glossy-wet coating
indicates that oil is entering the combustion
chamber.
2. A spark plug that is wet with gasoline or has sooty
deposits indicates either a faulty ignition or a
problem with carburetion.
Spark Plug Installation:
Spark plugs must be screwed in correctly to avoid cross-
threading, and tightened adequately to ensure proper heat
transfer. Do not over-tighten spark plugs.
CAUTION - Threads may strip in the aluminum cylinder
heads if over-tightened. Repair will not be covered under
warranty.
1. Inspect spark plug threads and clean if necessary.
2. Start screwing spark plugs in by hand. They should
screw in easily.
3. Torque spark plugs to 18 to 22 ft-lbs (24 to 30 N-m).
IGNITION TIMING
Timing advances electronically as the engine speed
changes.
Ignition Timing Check:
1. With engine not running, connect inductive timing
light to front spark plug wire.
2. Loosen timing plug from left side of crankcase where
two cylinders meet.
WARNING - Oil mist will exit timing plug hole when
engine is running. It is recommended that a transparent
inspection plug (not provided) be installed prior to
starting engine to prevent discomfort and possible
injury to eyes.
3. Start engine and reach normal operating
temperature. Using applicable manufacturer's
Ignition Installation Instructions, set engine speed
to recommended RPM. An inductive tachometer,
attached to spark plug cable, may be helpful if the
motorcycle is not equipped with a tachometer.
Tachometers designed for "wasted spark" ignition
systems may read half the actual engine speed.
4. Using dial-back timing light, set the amount of
advance specified (28-32
°
bTDC full advance
recommended).
5. Illuminate flywheel inside crankcase through
transparent timing plug with timing light. The "T:F"
mark stamped on the flywheel should be centered
in the plug.
6. Remove transparent timing plug and reinstall metal
one supplied with engine.
Ignition Timing Adjustment - TO BE PERFORMED ONLY
BY AN AUTHORIZED SERVICE AGENT - Use the Ignition
Timing Check Procedure, except as follows:
1. Before starting engine, remove ignition sensor
access plate from gear cover on right side of engine
crankcase after removing two screws.
2. Slightly loosen two screws which hold sensor plate.
3. While engine is running, slightly rotate sensor plate.
Clockwise rotation advances timing.
4. When timing is correct, tighten sensor plate screws
and recheck timing.
5. Reinstall ignition sensor access plate and install the
two screws.
STORAGE
If the motorcycle will be stored for several months, the
carburetor float bowl should be drained to avoid a buildup
of gum or varnish. The following procedure should be used:
1. Fully close the petcock.
2. Place small, open container below float bowl.
3. Unscrew drain plug to allow gasoline to drain into
container.
WARNING - Gasoline is extremely flammable and vapors
can be toxic or explosive. Adequate ventilation must
be provided and sparks or open flame avoided when
working with gasoline.
4. Reinstall and tighten.
