Cowboy...If Don (Twolane) has verified that the work at this Gail's place has been good in the past, and the same guy(s) are working there, that would be my next stop. With all the things you've spoken about, there are several possible issues mechanically that COULD be wrong, and no amount of tuning is going to fix that sort of thing. Sounds to me like whoever gets their hands on the bike next needs to start at square one and verify that the original work (mechanics) was done correctly, then go from there.
Then again, if you're looking for a good excuse to ride from Northern California back to Missouri, sending the bike to Jim is like money in the bank...it'll be right, or it won't leave his shop.
