I fixed mine long before the resister fix was around to which I kept pulling the sender from the tank and bending the float road litttle by little till it read like I wanted.
Correct me if I'm wrong, but I read a post somewhere, not on this forum which said after removing the sending unit from the tank, you can plug it back into the bikes harness, turn the switch on and adjust (bend) the float arm until you get the reading you want. Hence no need to keep pulling the tank off and removing the sender.
