Many years ago, I had a lovely FZS600 that I used to commute between Wolverhampton and Nottingham a couple of time a week. The one thing I hated were the poor lights, especially o the A38 in the winter.
I did a bit of research and found that a Gen 1 Fazer 1000 subframe would fit the 600, a little more research, I found the Gen 1 Fazer headlights and fairing and infill panels would fit straight on. The only thing I had to tinker with was the wiring loom for the lights, but it only took an hour of trial and error before I had fully working headlights from a 1000 on my 600.
If anyone is interested in doing this, I have all the components from a Gen 1 Fazer 1000 to do the conversion except for the LH infill panel and mirrors.
