After I finally got two new interlocking gear sprockets (one on the motor and one to the chain) from Victory ordered through Indian Motorcycles of Orange County, Hollywood Electrics finally agreed to do the replacement for me. The old sprockets had worn the teeth off. But just one week after Hollywood Electrics did the replacement, the two new sprockets wore the teeth off again. This is exactly what happened 20,000 miles ago when Brammo decided to then replace the motor. (Was the motor out of sync? Was the chain too loose? Was the tension spring too weak pressing the two sprockets together? Not sure.) Hollywood Electrics said they didn't have the equipment to swap the motor for a "new" one on eBay now, but instead suggested just welding the two sprockets together, especially since Zero electric motorcycles don't have the two sprocket feature that the Brammos have (which seems to serve no purpose and keeps breaking). So Hollywood Electrics welded the two sprockets together and two weeks later, the bike still seems to be running fine!
