The Bonneville lugging the Ural chair turned in 40-45 mpg. Solo I've squeezed 70 mpg out of it. I don't think a Ural solo would achieve this difference as the Bonneville had the gearing changed via the front sprocket (or do they change the final drive?). 70 mpg involves a lot of motorway at 55 mph, so is pushing the point a bit.
FI needs to be a modern system. I had BMW R1100's that never differed my more than 1 MPG either side of 40 regardless of running light and solo at 50 mph or fully loaded with a chair at 100 mph. It was pointless trying to save fuel as the system defeated you. The Brick seems to be similar. The Bonnevilles with FI I've had as loaners and the Tenere I test rode were mapped differently and weren't as smooth, but I'll take the 60 mpg performance in exchange for a bit of lurching at low RPM and cold engine weediness. I think if you want FI you need to be specific about efficient FI.
