I have an '04 R1100S, too.

Gas mileage is always in the 40s even when I run it hard.

I do hit the choke or enrichener to cold start, then turn off after the bike fires, feather the throttle for 10-15 seconds, and ready to go. Not a big believer in warming things up to engine temp before departing. I just run at low RPMs for a few mintues.

I have an '02 BMW R1150RT and it is a little touchier on start ups. Bikes are different.

Something is not right on that if you are getting up 20s or low 30s MPG for sure.

Does the S bike run fine?

If so, I think I would check the mileage a few more times with different brands of gas before being concerned. Remember one time one of the BMWs dipped down into the mid 30s and then the next tank of gas back in the 40s. Clearly a gasoline issue

Gas quality seems to make a difference.

S bikes are wonderful rides.
