The FZ6 doesn't have dogbones. It uses a shock directly connected between the swingarm and frame, cantilever stylee.
You would need to get a new spring fitted. So to answer your question, yes it can be changed. It's a fairly easy DIY job but you need something to compress the spring - a motorcycle shock spring compressor is ideal although you can use ratchet straps.
