I would get the adapter and reg from Hugh's handbuilt. It is cheaper to find a stator and rotor from various sites, but Hugh has it all if you don't wanna search for it. The PAMCO is the way to go if you WANT to get rid of the TCI. I had the same setup as you, and installed all that BigJimmy recommended and it SOOOO much easier to install and less problems. I don't know if you want to, but building a harness takes no time once you start doing it. I was intimidated by it, but once you start running the wires it all makes sense and is really simple.
A second thing is, with the stock charging system, its not if it fails, but when. I highly recommend that change as well. You wouldn't need a battery if you wanna kick only bike. You can use a small SLA battery or capacitor if you wanted it REALLY concealed. I installed the rotor, stator and Pamco in one morning and wired it all that afternoon.
