My FZS 600 is the same in as much it does not need choke unless the temp is below freezing point, I know that a leaking exhaust system can cause a backfire in the exhaust, but that is usually on the over run when slowing down, but it might be worth checking that you have all the exhaust manifold nuts still in place, I did loose one of mine a couple of months ago.
Good luck with sorting it out, its always worrying if its just started the misfire and nothing is obvious, are the inlet manifold rubbers all OK and not sucking air weakening the mixture? just a thought.
