zlagger,
I have an Agni 95R motor that was on my 2010 DS. It had about 10,000 miles on it before the brushes vaporized. I replaced the brushes and brush holders ($270) but have not had to put the motor back in the bike; I have a replacement motor that Zero provided me that I have been using. I tested the rebuilt motor by hooking it to the leads and the motor did what it was supposed to but it had no load and I am not an expert. This motor has not been "fully refurbished".
You can find motors and parts at Jozztek in the UK, that is where I bought the parts and the company is very good. New 95R motors are selling at $1800 and refurbished are worth $1200 (plus shiiping).
With the description provided above you may put this motor in the abused category but that is up to you.
If you are interested in buying the motor let me know. I am in Oregon, USA and I have a fine used Agni in the original shipping box.
