SPECIAL NOTES: If you plan to use another programmable fuel injection module, it is best to consult the manufacturer to be certain that it is compatible with the S&S single bore system and has enough tuning capability for your engine configuration. Installation of S&S throttle body on 1995-2001 bikes requires S&S ECU. Single bore throttle bodies are not compatible with stock Magneti Marelli ECU.
