Swopped to FZ1 bars today, woweee, what a mod.
Easy to do, just one hole to drill, didn't even bother filing the wee knob off, reckon you never know if it might be handy later.
On full lock, it's at the absolute limit of acceptable clearance. Risers would incur fouling the screen for me, I have the Puig touring one. Don't need risers though.
Handling and comfort massively improved. Unbelievable difference, like riding a different bike.
