CAUTION
4- Start screwing spark plugs in by hand. They should screw in easily.
5- Torque spark plugs to 18 to 22 lb-ft (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. Set engine speed to RPM given in engine specications.
NOTE: 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 specied, found in the engine specications or on the emission tune-up label for the engine.
5- Illuminate ywheel inside crankcase through transparent timing plug with timing light. The "T:F" mark stamped on the ywheel should be
centered in the plug.
6- Stop engine, remove transparent timing plug and replace metal one supplied with engine.
Ignition Timing Adjustment
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.
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- Set plug gap 0.040”to 0.045.”
3- Apply anti-seize to threads of spark plugs.
TO BE PERFORMED ONLY BY AN AUTHORIZED SERVICE AGENT. Ignition timing is not to be adjusted. Contact your authorized S&S dealer
if service is required.
CAUTION
NOTE: Engines with Super Stock® ignition come timed from the factory and have a tamper proof seal. Breaking this seal will void the engine warranty.
Storage
If the motorcycle will be stored for several months, the carburetor oat 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 oat bowl.
3- Unscrew drain plug to allow gasoline to drain into container.
WARNING
Gasoline is extremely ammable and vapors can be toxic or explosive. Adequate ventilation must be provided and sparks or open ame
avoided when working with gasoline.
4- Reinstall and tighten drain plug.
