...one of my specific plans for the trip is to observe lane splitting. I can't say if I will try it myself, but if conditions seem safe and I feel OK, I will....
Do you have FZ1 mirrors? If yes, leave 'em home and put the OEMs on. When lane splitting on a KZ1600 it was wide enough that I had to adopt a slight weaving pattern to keep my mirrors from hitting the car mirrors. Trucks with towing mirrors were sometimes high enough to avoid problems, but if they were lower they were a problem to miss. Following an experienced lane splitter really helps the learning curve but ride your own ride, you don't have to keep up.
I was following an experienced lane splitter on his Harley (with pillion's CA sister) and he was a lot more aggressive than I was, but I made up for it when I could shoot gaps in the traffic with high horsepower and tons of torque
Harley rider later commented about the rate we could close distances. I will observe that at least 40% of his ability to lane split was facilitated by his concussive exhaust announcing his intent or displeasure.
I also learned about filtering to the front of the traffic line at traffic lights and work sites. In New England that would result in sure death at the first attempt.
