-  * Spark ADVANCE - is how soon, BEFORE the piston reaches top dead center (all proper timing is BEFORE TDC) that the spark plug fires to start burning the mixture. The faster the motor is turning, the sooner you need to start the ignition (more advanced it needs to be) so that the power of the expanding gasses starts pushing on that piston as soon as it starts moving downward and pushes as long as will be beneficial.

 Important: Be sure you are on the compression stroke of the front cylinder when setting the Static Timing. When you rotate the engine (as follows) be sure you feel the pressure in the front cylinder spark plug hole is building up as you rotate toward the TDC mark. Turn the engine over as often as necessary to guarantee you are on the compression stroke of the front cylinder. Important: Be sure you are on the compression stroke of the front cylinder when setting the Static Timing.

-The Nosecone Ignition unit (98-03 not-S) can be **statically** timed (without the engine running) using the built-in LED. The procedure is to manually rotate the engine (bike on lift, 5th gear, rotate rear tire to rotate engine) to position the engine to TDC (front cylinder compression stroke) using the timing hole to look for & center the vertical line. Then, turn the ICM/Cam Sensor Plate slightly clockwise & counterclockwise to find the exact spot where the light switches between on & off - Lock down the plate.((aswracing comments ​http://​xlforum.net/​forums/showthread.php?​t=1662422)) In this way, the ignition module is synchronized to the engine (TDC) so that it can effectively calculate the proper time to fire the spark plug BEFORE TDC.+The Nosecone Ignition unit (98-03 not-S) can be **statically** timed (without the engine running) using the built-in LED.

 The Cam Sensor Plate can be rotated slightly to accomodate getting the timing mark in the center of the timing hole. You can also move the plate to change the base timing (thus moving both curve sets wholly up or down in all rpm ranges) by setting the timing to a few degrees more or less than the specified advance timing mark. For 1991-later models (right side window), you should be able to see the timing mark move to the right edge of the hole (more advanced) or the left edge of the hole (less advanced). You might find that a Timing Light with a Dial Back feature allows you to set a specific alternate timing setting using the TDC mark as a reference. The Cam Sensor Plate can be rotated slightly to accomodate getting the timing mark in the center of the timing hole.

 **How-it-works by Steelworker:​** An ignition coil is a pulse-type transformer,​ consisting of a low voltage primary winding (the input) and a high voltage secondary (output) winding, wrapped around a laminated iron core. The primary circuit is completed by the points or electronic ignition module closing the primary circuit to ground. The flow of current in the primary windings induces a strong magnetic field in the laminated iron core. When the primary circuit is broken (by the ground being removed), the strong magnetic field in the core collapses suddenly, which induces a high voltage electrical discharge out of the secondary circuit, thereby, producing a spark strong enough to bridge the electrode gap of each spark plug. **How-it-works by Steelworker:​** An ignition coil is a pulse-type transformer,​ consisting of a low voltage primary winding (the input) and a high voltage secondary (output) winding, wrapped around a laminated iron core.

 +===== FYI: Buell Ignition Modules =====

 +The Buell X1 was only made from 1999-2002. It is EFI based, with a single ECM (engine control module) that controls both spark and fueling. No separate ignition module at all. The same is true for all 1999-2002 Buell S3 models. The parts books refer to the ECM as a "​control module"​.
 +
 +The 2001-2002 ignition module found on the M2 is an actual ignition module. Since the M2 is carbureted, the module provides control only of the spark advance but no control of fueling. Although it has a similar appearance to the ECM found on 1999-2002 X1 & S3 models, the part number is different and the parts books refer to it as an "​ignition module"​. This 2001-2002 M2 ignition module is also a bastard, not found on any other Harley or Buell, and no aftermarket replacements available for it. The only high performance version of it I've ever seen was the Buell Pro-Series version which was offered back in the day. It's an issue when someone comes to us for a performance package for a 2001-2002 M2. We basically have to tell him to chuck it and wire in a nose cone module.

 +The other carbureted Buell models (1995-1996 S2, 1996-1998 S1/S1W, 1997-2000 M2, and 1997-1998 S3) all came with 8-pin modules, except 49-state 1995 S2's, which came with 7-pin modules. These are similar to the XL version ignition modules.
 +
 +There'​s an adapter available to connect an 8-pin module to a 7-pin bike, and another one available to go the other direction, i.e. a 7-pin module to an 8-pin bike.
