Many many thanks guys, can't wait to try your solution. Am having the same problem, no fuel gauge reading but the low fuel light would come on after burning up 3.5 - 4 gallons.
As a twist to the plot, my clutch switch was acting up so I pulled out the two wires and connected them to an on/off switch on the handlebars. To really play with a thief's mind, the switch has to be in the off position for the bike to start. That switch is right next to the auxiliary light switch, with a normal on/off function. You have to know the right combination of which switch is off but really on, and which is really off to start the motor. So effective I don't bother removing the key anymore.
Next time starting the bike, will try turning off the clutch switch to see if the fuel gauge works again. Have already replaced the fuel float, fuel filter, triple checked the wiring thinking that might be the problem. Never dawned on me that the clutch switch could be the cause of the fuel gauge not working.
I don't have a side stand, the was removed to make room for the bike sub-frame to attach a sidecar. But twisted the two side stand safety wires together to eliminate any starting problems.
Thanks again for your sharing your discoveries.
