I went with the bar kit from Wetbike Japan. The only mods I had to do where to the master clutch & brake cylinder stops, so that the lines could be rotated slightly so as to not hit the fork tubes. Doing this allows you to get the right setting for the clutch & brake levers, to suit your hands. The bars with that kit are shorter, but have a bend similar to the old super bike bars, and there are no clearance issues with the fairing.
They also make a police bike handlebar kit that includes longer throttle cables and a few other pieces. Their site is worth looking at.
