I know I can change a tube roadside, and I'm getting the Stopngo repair kit with the hose that screws into your spark plug port, and turns a cylinder into a compressor. I have a full rainsuit for the drizzly days.
I don't think 500 miles a day is unreasonable. We'll figure out a good cadence of riding and rest, and definitely start out very early in the morning. I'm putting together a map of our proposed stops for the night. I'll put a link up on this thread. Basically, we have to be back by May 26th. We're planning on leaving on the 18th from Sacramento. So really like 8 days to do it. Thanks for all the support from everyone. I'll give everyone the full skinny when it's crunch time, route, contents of the repair kit, etc. Some pics before we set out.
