I have a 2014 non ES Super Tenere with 44,700 miles.
I've never kept accurate track of my MPG, other than the computer on the bike that provides the average MPG. My computer ordinarily read in the vicinity of 44 MPG average. On the fuel gauge, I consistently would ride just at 75 miles when the first bar disappeared.
On February 2 I replaced the original battery on the bike. After replacing it, I happened to notice that the average MPG on the computer was showing substantially lower than normal; in the low 30's. I attributed that to the removal of the battery, and thought that the computer might have to re-establish some sort of baseline. Gradually the MPG began climbing back to where it normally was; it got as high as 43.8 MPG, but then began to drop back again. The average on the computer now reads 42.6 MPG. In addition, I noticed that the first bar on the fuel gauge started disappearing at around 60-65 miles, rather than the previous 75. I figured I'd let it go for a bit and see if it settled back to normal.
On February 28th I replaced the spark plugs. One of them had been corroded from water intrusion, so I decided to just replace the four of them. I checked and set the gap before they were installed.
On March 1st I synchronized the throttle bodies.
On March 15th I figured I'd check the actual MPG after I got fuel, and the math worked out to 39.6 MPG.
On March 18th I changed the air filter and again synchronized the throttle bodies. I would note that, on this occasion, I reset the standard throttle body airscrew back to it's factory original setting (fully closed) and then opened the screw a half turn,
Today I checked the MPG again after a fuel stop, and it worked out to 35.9 MPG. The first fuel bar went off today at 61 miles.
The problem is that I don't have an actual baseline to refer to before and after the battery change, since I was never in the habit of checking the actual fuel use. The only thing I can say that changed is that the first fuel bar now disappears a lot sooner than it did before the battery change. I can't imagine anything I did that related to changing the battery would have anything to do with fuel consumption, and I noticed the fuel consumption issue before I did any of the maintenance described above. The bike appears to be running normally; power delivery is the same as usual, and it idles the way it's supposed to. I've been using 93 Octane fuel, and the last two stops were at different stations. Based on the fuel gauge, it's seems that I'm using more fuel than before the battery change. Any suggestions from people more knowledgeable than I what might be going on here?
