I went that route. Used a Renthal (758-01-BK) and some short risers.

The risers where very hard to find in stock for what I needed. As it is the bolt is a little on the short side. Enough room for a nut with lock tight on it, not enough room to use a locking nut. I plan on swapping these here shortly, just didn't have the option when I originally did it.
Didn't have to change any cords. All I did was cut a zip tie to make it easier.
The combination put the handles in pretty much the same location as stock, however the angle of the bar is much better on my hands. To have my wrists straight on the factory setup I had to tuck my elbows in, these are more natural for me.
I'm a big guy, most people may not have this issue. I didn't even think about it on the first FZ1 I had, just had the dealer mention something he did on his and realized that was a good idea.
Off hand I want to say they are slightly wider than stock too. Maybe like an inch on each side. I tapped mine to use factory bar end weights. The bar can easily be cut down.
Those Pazzo levers are Satin black, not the standard black, in case anyone in the future is looking for an example.
