I haven't tried it with the Fazer but did the following on a previous Honda, which also had bar ends that screwed in to a threaded weight inside the bar. Might be the same, or it might be completely different, but worth a go maybe!
There were two holes drilled into the bar, one ontop, the other below, around an inch from each end of the bar. To remove the weights inside, you had to depress two clips/buttons inside the holes and slide the weight out. I remember just rolling the clutch side grip out of the way to do this, but cannot remember what I did on the throttle side - I'm guessing you might have to remove the throttle assembly, so it'd make sense to start with the clutch side.
