A. Cold Starts

1. Open fuel petcock.
2. NOTE: When motorcycle is not running, fuel petcock/shutoff valve should be turned off to prevent possible leakage should needle and

seat not seal properly.

Gasoline leaking past inlet needle may flood engine causing oil contamination and engine damage.

Gasoline leaking past inlet needle may flood engine and surrounding area creating a potential health and fire hazard.

3. Prime engine with one or more squirts from accelerator pump. Ambient temperatures below 60° may require increased priming, up to

6-7 squirts depending upon exact temperature and carburetor jet size.

4. Lift fast idle lever, to fully raised position.
5. Turn on ignition.


NOTE: Some engines, especially those equipped with magnetos, will start easier if given two prime kicks BEFORE ignition is turned on. For reliable starting,
magneto should be equipped with kill button to disable ignition for prime kicks.

6. With throttle closed, kick engine through or engage electric starter.
7. If engine fails to start immediately, crack throttle enough to barely open butterfly and continue to kick or engage starter until

engine fires.

8. After engine starts, position lever to maintain rpm at approximately 1000-1200 rpm with throttle closed. Lever may gradually be pushed

down to closed position as engine warms. Engine should be warmed sufficiently to idle with fast idle lever off in 1 to 4 minutes or after
a few miles of riding.

NOTE: Operating engine with fast idle lever up for excessive time will result in fouled spark plugs. Push lever completely down as soon as engine will run
smoothly without enrichener.

B. Hot Starts

1. Open fuel petcock.
2. Turn on ignition.
3. With throttle closed, kick engine through or engage electric starter.
4. If engine fails to start immediately, open throttle slightly and continue to kick or engage starter until engine fires.

C. Troubleshooting Tips - engine will not start:

1. Fuel supply exhausted.
2. Weak or no spark - discharged battery, worn points, faulty condenser, ignition module, coil, spark plug wires, or magneto.
3. Plug gap too wide - S&S® uses .025" to .030" plug gap on engines with points type ignition and stock coil. Electronic ignitions and high

output coils can run wider plug gaps.

4. Improper ignition timing - Worn or poorly maintained mechanical advance units sometime stick in advanced position causing hard

starting, kick-back and erratic idle.

5. Tight tappet adjustment - If solid tappets are adjusted too tightly, valves may not seat properly, and the loss of compression may

prevent the engine from starting.

6. Improper idle mixture and/or engine idle rpm setting. If idle mixture is set incorrectly, throttle plate must be opened farther with the

idle speed screw in order to maintain idle speed. This reduces manifold vacuum and makes the enrichment circuit less effective. See
Adjusting Carburetor -Idle Circuit on page 15.

7. If the enrichment device feed hole in bowl is plugged then clear with compressed air.

Do not use wire or drill to clear hole. If size of hole is changed, starting system will be altered and carburetor bowl irreversibly
damaged.
