Congratulations on that 85mpg tank
I made one too, the best this year: 2.75l/100km=85.6mpgUS, which is 58% 2-up. I had a worse successor too, and I even know the average: it's 2.95l/100km, a tad worse than 80mpg... it breaks a long row of 80+ tanks. Tough luck
But at least it was a hundred percent 2-up. Much of it on main roads, in high speed pulse&glide. But I tried to slow down as soon as the traffic got lighter...
