Stock, they do run rich.

2. Make sure there are no restrictions in the exhaust.
3. I am assuming that the bike runs ok with no FI light.
4. Check for hidden FI codes. There is an unused 2 pin connector in the tail section. Can be jumped with a paperclip. See manual for details.
5. What is your running battery voltage?
It is possible that the FPR has a pinhole leak. This will make her run rich to say the least. Pull the vac line off the FPR. It must be DRY of fuel. What is your mpg?
