The worst was right at 3200-3500 rpm and 6-8% throttle. The ignition has a big advanced timing spike centered at 3500 rpm. On the ramp up (3200-3500) it had a very touchy throttle. On the ramp down (3500-4000) it seemed to have a huge flat spot, which took a lot more throttle. This is right at 55 mph.
This sounds exactly like what I'm seeing with about 80 miles on the bike. I'll give it a little bit of time to sort itself out. I hadn't considered the warranty being an issue but it's probably wise to hold off on invalidating anything until I'm sure there are no major problems.

Thanks all for the advice. Orange Crush has been an amazing resource for this new owner.
