I just got back from a ride and I fueled up before I left and when I got back. I rode 154.3 miles. Now granted, I only broke 100mph a couple of times for short periods. I rode twisties at a fairly good pace for the most part and then had some time on the interstate getting to and from. When I filled up after the ride, it took 3.822 gallons. That works out to a little over 40 MPG.

I think you must be right. You thought you filled up, but forgot to. That would explain it. Otherwise, you'd be smelling the fuel leaking out.

Glad you figured it out.

 

Here's something I do religiously every time I fuel. I reset the trip reading.

This way, there is never any ambiguity and I always have a pretty good idea about how much gas is left in the tank.

Try it...its a pretty good system.

 

ditto,

BTW, first fillup got me about 38.5mpg. Must be because the engine hasn't broken in and I'm uneven with my throttling (losts of wasted fuel).

 

i do the same. last tank i got 155 miles on 3.8 gallons. about 100 miles of that i was at/over 100mph on the highway. that's right at 40mpg.

 

What about an absolute thrashing of the bike.Would your mpg drop into the teens

 

this is also something i have been wondering.... there are times when i can get a 155 miles to a tank...then there are others like the other day when my light came on at 92 miles... I fill it up to the top everytime.... dont understand why the length of the fuel is so unpredicatble.
