If your fuel gage is working it is the thermistor in the tank, I think there is thread telling how to replace the thermistor without replacing the whole fuel sender.
Always wanted to do that, but does not get cold enough down here for the lake to freeze over.
Glad y'all had a good time, just make sure you do not steal someone's girlfriend and they push your shack into an ice hole.
I agree helmet is best but it can make a sore neck, handle bar too much vibration also had good luck with the suction cup mount on the fairing right above the headlight.
