| - | 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 | + | 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.

| + | 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 " | ||

| + | 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 " | ||
