Anyone Else Had Trouble With A T100 Gas Gauge?

I bought a new T100 a year last March and have had problems with the fuel gauge. My problem was, no matter how hard I tried to sqeeeeze in more fuel the gauge wouldn't show more than 7 bars. At first my dealer changed the rev counter, and handed the bike back to me, but that hadn't solved the problem. Next they changed the sender unit which cured it. Now the eighth bar works but only when the tank is totally full to the brim.

 

FWIW I’m pretty sure my Speed Twin gauge sticks around 100 miles. From what I’ve seen, very similar set up. Hovers up and down for 20-30 miles. Potential 3rd warranty issue. 1800 miles on the bike.

 

Little glitches on my 2020 T100 I figured were just quirks, but now I'm wondering if there's a problem: Doesn't reset to show full until sometime after I've filled it and ridden a bit; the miles to go indicator can fluctuate strangely. Will have to pay closer attention to the bars.

 

Yes my 2018 exactly the same. It does sometimes and others it just stays about 5 bars. But eventually does rise.
