cdogg,
Good luck with it. For most of the people I have talked to and read on, no real issue with it though Purple Dog and some with the air comp have some issue getting the room for a neat install due to the HCI placment.
Raywood should be a good resource also and hopefully when he gets time, will put up some more info and pictures from his install.
May be carefull on what other stuff you add to it such as HID. Seems some have had issues with HID kits, but then again it may be the HID, the install or who knows for some of the problems that people have reported on here were not just limited to PDM kits.
Install is pretty striaght forward and the more info you can get form people that have installed, the better it will be for tips and stuff, so search to see what is out there. Also take your time to lay out the wiring routing, look at Raywood photos for how he mounted the relays for the horn and starter. Mounting on the side can be a PITA with the side covers, consider alternative location like front of Battery Box.
Good luck and let us know how you make out. If you do it, try to get pictures and write up and post any suggestion, problems or tips for helping out others down the road.
Overall I think it is starting to look like a good product and maybe what BD should have done in the first place. Just be cautious of what accessories you may add, but in fairness anytime one changes from stock to some custom work, things may not alwasy go as expected.
Safe riding!
