Shane: both Lorne and I have the HID conversion kits in our bikes.. and love it, way more light, and alot more coverage on the road.. everyone says they are far more noticable.
we bought a kit for a truck, and split it.. as it contained 2 bulbs.. 5000K bi-xenon, 2 ballasts.. slim, and just ordered a second relay..
Neoracer on the 1200 forum has a good write up on how/where to install it on the 1200, and for my sabre.. it was put the ballast in a brace under the headlight and the relay inside the frame at the front. Using the original bulb plug gives a hi/low beams.. hence the use of a bi-xenon bulb.
