My 06 Busa's temperature needle stays put at the very bottom of the temperature gauge. When I turn on the bike, all the other needles dance, even the red LED in the temperature gauge lights up, and then turns off. All my fuses seem fine, and the radiator fan turns on while idling, but I cannot figure out what is happening with that gauge. Do I need a new sending unit? Is it that my needle somehow became unconnected to the gauge? How can I find out, and has this happened to anyone else?
