The workshop manual is available for download ( see wiki section of the forum). That says that if a good battery is allowed to discharge to 12 volts and the engine is then revved to 5000 rpm a current of greater than 20 amps should be possible. More importantly if you do not have an inductive type of ammeter the voltage under normal charging conditions should be around 14.5 volts. You do need to know that the battery is good because a bad battery can give all kinds of strange readings.

Not a lot extra, I ran a electric jacket and it was fine as long as I wasn't in stop and go traffic all the time.

The normal charging voltage is ard 14.6v.there was a time i forgot to off the bike for like 5 hrs.the next day,she was able to start up just fine but the charging voltage while on the move was showing only 12 plus vollt.
After running for quite a while on the next day,the voltage was able to return to normal by the following day.
