I posted some time ago that the petrol gauge on my 2019 650 XT was refusing to go down below half full. I have worked round this since then by resetting the trip to zero each time I fill up and checking that against the range remaining. Normally when I fill up the range shows about 230 miles. Yesterday when I filled up the tank took 11.39 litres and the range remaining before filling was 90 miles. After filling the range jumped to 311 miles ! By my calculation that 70 mpg. I don't know if something else is brewing with the gauge itself but will wait & see. Incidentally I mentioned the problem to the dealer in July when the bike went in for it's annual service & MoT. They said they were very busy but would have a quick look. The mechanics report said they thought I was looking at the temperature gauge and not the fuel gauge !. I decided not to be really offended, paid & left.
