replacement stator

You will want to get a "narrow" type rotor made for the S&S motor. Compufire has one for around $100.
Why are you replacing it?
If the charging system is working correctly, it will charge the battery at idle...usually around 14 VDC
If the voltage fluctuates a lot at battery when the motor rpm's are changing, then you most likely have a bad rotor or stator. If you not getting enough volts, at least 13 VDC, then you probably have a bad voltage regulator. If over 14.6 VDC, then your voltage regulator is bad as well.
A typical test on a good stator will show around 19 VAC at idle, and climb up around 50 VAC at 3000 rpm. You also want to check with an Ohm meter for any opens to ground in the stator.
Have you had th primary open yet to check the Rotor? Sometimes the front Compensator sprocket nut will loosen up and cause the rotor to fail. The inner splines end up grinding off from the splines on the output shaft of the crank.
I would say, replace what is broken...why spend the money on a high output 3 phase if you don't need it?

The statement about getting a multi-meter is my signature because I personally think anyone who wants to save some hard-earned money should have one. Even if you don’t do your own work, a multi-meter can help you to keep from paying for unneeded repairs. For example you could find out that you just have a bad circuit breaker and not have to re-wire your entire house like some sham contractor tells you. But it might also just give you peace of mind if a good contractor tells you that you have a bad wire going to your bathroom and you use your multi-meter to find out that the breaker is good so it must be the wire (cause you already checked or replaced the outlet)

And Andrew, my mastiff’s stator must be weak or going out, cause mine does not charge at idle. If I let it idle too long, especially after cranking, I get the flashing everything on my speedo indicating low voltage. It may be putting out at Idle, but not enough to overcome what is being used, that’s one reason I want a switch to be able to turn off the lights if I want.
