Your handlebars are Heli Bars and sell new for close to 400.00. If you don't want them, clean em up and they will sell in no time. When I bought my 2004 B-12 it was the first mod I made and a taller windshield the second.
They are remarkable bikes with bulletproof engines. Before you spend a lot of money on farkles I'd encourage you to get a good look at the cams and inspect for scoring or flaking. They were a known weak spot. Otherwise, these bikes are reliable and will run forever.
I traveled from St. Paul, MN to the tip of Newfoundland on mine and it never missed a beat.
