There is now a motorcycle specific kit that includes the parts Chuck listed early in the thread PLUS a finishing shroud (bezel) for $150 plus shipping. I guess Chuck got them thinking .There isn't a motorcycle specific kit with selectable options on their website, so I just called them and had them put together a kit for me with my specs. They still gave me a bundle discount too, so it was only $150 for the custom kit.
I am finally doing my conversion. I have to press my race bike into road service for a week-long trip from Western Pennsylvania to Maine and back. My brother, who is flying in from Oregon, will be riding my usual road bike. I purchased one of the light kits and a set of mirrors with integrated turn signals. I'm going to follow Chuck's directions pretty much to the letter, although I am interested in seeing if the included bezel will finish the front end or if I will need to go the rubber gasket route.
I'll post as the conversion moves along.
