I've had 2 that just went completely dead. I've had one that would start and idle and cut out at higher RPM's. I had another chug along at idle, but would not go over 3000 RPM if throttle is pinned.

There are all kinds of symptoms depending on if the stator goes totally bad or is "going" bad. Every once in a while a guy has bad reeds causing a "miss" and thought that the stator was going bad. In some cases you get no spark. Sometimes you get weak spark and sometimes you get a missing condition a couple of seconds after you push the throttle. There is no 100% sure easy way to test the stator. You can measure the ohms and possibly see a bad stator but you can also get "good" readings within spec and still have a bad stator because it is shorting out internally. You can get a voltage output tester and it still shows "good" output even though at running conditions it is not putting out adaquate voltage at rpms. You can also have a bad coil. I read somewhere a while back that if you have all of your plugs out, pull it over and one plug seems to be bright blue and one has more of an orange or "weak" spark that your coils are bad. When I checked my triple a couple of years ago I had one plug that was very bright blue when you pulled it over and the other 2 were weak or "orangish" looking. There are people who have never had one go bad on them and I have had 2 sets go bad on me. The least likely failure in the system is the CDI box. Of course they can go bad too, but they usually last. Of course you can swap out parts to see which one fixes it. I ohm tested my coils and they showed good but my sled was missing as soon as you held the throttle to the bar for more than 3 or 4 seconds. After swapping out a set of coils it was fixed. Of course you should make sure all connections are good including the ground, no wire insulation is worn, there is no moisture in the connectors ect. The 3 main symptoms is that it either wan't start due to lack of spark or it'll start and idle ok but after you get higher rpms it misses a little bit (or a lot) or it will barely start and won't go anywhere.

I forgot to mention that you should also check your jumper wires between your coils. If the connections are loose, it'll cause an intermitten "miss" when riding and it acts like a stator going bad.
