Fuel pressure regulator part number
I'm looking for the part number for the fuel pressure regulator for a 2004 F4i.
I see that #20 here has 3 different part numbers:
THROTTLE BODY
How would I determine which is the correct one?
16740-MBW-J21
16740-MBW-J31
16740-MBW-J32
I'm troubleshooting poor fuel economy (~30mpg with very mild riding) and I've come across several posts where the FPR was the culprit and is considered to be a common part to fail on these bikes.

Welcome Crew Technician
Go with the J32. The most updated part number and has replaced the previous ones. The others are not even on other fiches.
You can pull the vacuum hose off the left of the FPR and see if its leaking. If it is not it is probably fine. Could still be working incorrectly but the leaking is a sure fire way to tell.
