I too called Spirit in San Jose about getting a flash update to the latest. They said they had done one before and the mechanic that did it wouldn't be in until Monday (I called on a Saturday). Seemed like nice folks and gave an air of competence.
I also called Arlen Ness in Dublin and they said they weren't yet up to speed to work on electrics, but keep checking back. Also seemed competent.
OTOH, I called Powersports of Vallejo and when I inquired about the Empulse TT, they said, "What?" When I let them know that was Victory's new electric bike, the reply was, "Oh, yeah... no, we don't know anything about that."
