The manual says 240 watts @ 5000 rpm. Some say that means around 150 average. There isn't a high output stator available for us, unfortunately. Every manufacturer says there is no need for one. Apparently they make up customer feedback instead of listening to it.
There really isn't a consensus on the Raptor 700's ability to run extra lights. I saw a post from a guy who said that he ran two 55w Hellas and he was fine. Another guy said that with his stock lights converted to HID (10 more watts than stock) he eventually ran his battery dead one night. Yet I have spoken to others who say that they were able to run Baja Designs' Fuegos in conjunction with their stock lights (80 extra watts) with no issue. It's pretty much a crap shoot I guess.
I have the HID conversion and I have two 35 watt Kragen HID's on my handlebars, so I am personally crossing my fingers that my set up will work. I haven't really tested it for an extended period of time yet.
