Although the AMM-P3 was designed for the HD® TwinCam engine, it will also perform flawlessly with newer Sportster® models.
The new 2004 model Sportys (rubber-mounted) have a crank-sensor and tooth-pattern similar to that of the TwinCam engine. The ignition coil is also the same. This makes installation and adjustment similar to TwinCam engines.
The AMM-P3 ignition can be mounted at the coil (using the standard Softail coil-mount) or under the seat.
If you have any questions, feel free to ask.
