You can call S&S for a list of local dealers in your area and possible service shops. However, as the X-wedge and its parts have obviously been discontinued, they may be hesitant to work on it.
If you have problems and need a potential reference, I have worked with Stephen Gougeon, the owner of GMR Performance here in Fort Worth, TX. He actually wrote the tuning maps for Confederate Motorcycles X-Wedge bikes; one of the only other commercial application of the X-wedge engine. That being said, he hates the X-wedge, so if you do call him, be prepared to hear an elongated diatribe of what a bad engine it is and what a bad choice it was for any application. However, he is intimately familiar with it and may be able to refer you to someone in AZ who can work on it.
