We'll thanks everyone for the awesome replies, while it gets me no closer to the endgame , it does help out. I get the feeling some of you do not think I'm equipped for this trip , if you go halfway down in the link below
You will find a complete trip pack list, as for airlines I cannot seem to get a straight answer yet, plenty of power in CA, since the batts will only be used intermittently a charge could last for days, as for sacrificing the frame bag I would be ok with that if it helped the end result. I do not want any drag anymore then I already have. Dirt roads everywhere , thinner tires were explored then ultimately scrubbed. I was thinking a 80cc kit would be more then enough to power up hills. Gas is readily available in CA as I recall!
