I found the problem, when i play the float without start the engine, everything is in perfect working condition, but when i start the engine & i play the float, the fuel indicator is inaccurate. Anyone know to solve this problem?

I already tried running with full tank, but I already running more than 100km the indicator still not moving, that's unusual practice. just now I tested the float with multimeter, there is no abnormal ohm (full position - 8 ohm, empty position 98 ohm)

I dun think is the tank float problem cause the gauge never show the actual quantity of petrol when the bike moving. when I switch of the key & turn on again the gauge will show the actual quantity of petrol.
