Not specific to the Fazer 1000 but generally it will start charging at not much above tick over speed, say about 1,500 rpm, if you don't have any lights switched on. If you have the lights on it will be at a slightly higher speed because of the extra load. The generator will be producing current as soon as it turns over but will probably only reach it's maximum output at about 4,000 rpm. or more. That doesn't mean it will charge the battery any faster at 4000 revs than at say 2,500 revs because the input to the battery is regulated to protect the battery from too much current.
Just how long it would take to bring a battery back to 100% depends on many factors as well as how low it is to start with. Far instance a good long run in the country side at reasonable speed with few stops will do a lot more good than the same amount of time spent in town with frequent stops at traffic lights and junctions on tickover with brake light on and winkers going and aggressive use of the horn. Thinking about it, a ride in the country side will probably do more good for your personal well being as well.
