First off that is not how you check your "charging system" not a magneto! on these bikes you have a Stator that is in the LH side cover on that engine and you need to check the windings for continuity and for short to ground. I would consult a local dealer for voltage output test spec's on the stator. next is the regulator rectifier, this can be tested with a meter and again consult your dealer.
when checking battery voltage while running it is common to have to bring the engine up to a higher speed than idle when testing the charging system, I would advise around 2500~2800 rpm and expect voltage to be 13.5~14.5 volts.
