If you buy OEM FZ1 bars, they aren't going to be cheap!
There's probably something aftermarket in the same shape, cheaper.
Like Ray said, there is some play in the cables, wires, and hoses.
Risers, from various sources, are a cheap start......
Go ahead, and rotate the bars back a bit. A lot of how the bike is assembled, and by who...determines on how the bars are 'set' upon assembly.
