Default Replaced FPR - mpg drops from 39 to 35.

Replaced the fuel pressure regulator (was getting the 2-blink FI light error code & had already replaced the map sensor).

Lo and behold the bike runs very much better. However, mpg has dropped from 38-39 down to 35. Also, she runs about 1 to 2 degrees warmer (which I'm attributing to a slightly leaner condition w/ the new fpr - old plugs showed too rich of a mixture).

Any ideas on the drop in mpg?
