On my previous bike ('96) I ran 4 Ricky Stator Aluminators (2 in the stock location, 50w each; and 2 on the handlebars, 35w each) and his 260w dual-output stator (no longer available). I also ran his battery kit (also NLA) so I could power these and my GPS, tail light, whip light, and a little LED without worrying about keeping the R's up alll the time.

I'm planning to run HIDs on my current bike ('00) but am waiting to see Lazerstar's "improved" HID they're supposed to be coming out with ~ January. I want to do another battery like before (so I can run the HIDs and hardwire the GPS to it), but it will have to be a custom fabrication this time unless someone knows of another manufacturer making battery kits.
