Just posting my personal experience with the flash from AC. Hardest part was getting my big clumsy hands on the back side of the panel to remove that one allen head screw. Re-installing went much easier. So, anyhow, I shipped mine last Monday, and had it back on Saturday.
I had a busy weekend doing other things non bike related, and have only put about 20 miles on it since, but wow! what a difference. I went with the most aggressive options in both T and S mode. I agree with AC that this may not be the best setting for the majority of people out there, but I think it's perfect for me. Thanks AC for making this bike fun to ride!
Take care,
Chuck
