gas cap question
i've noticed this problem a few times but, i went to the pump and filled up. went riding and after 50 or so miles the gas gauge reads less that half, by 80 miles it reads just above a quarter tank. so i go back to the pump and i put fuel in and it's 1.8 gallons. why does the gauge keep doing that. anyone else have this trouble. i want to replace them anyway and possibly go with a dummy for the left side.

I have a kuryakyn gauge on my left side tank - it's the LED style and seems to read pretty accurately. The one issue I have is that after every fill-up my fuel light comes on (the one on the speedo face), and stays on for 50-75 miles. Sounds like a different but possibly related issue? Maybe a float or sending unit problem?

I still do this as well. From back in the day when I had no gas gauge at all. Just remember to reset the trip meter at every fill.

Your sending unit in the tank is probably bad. Like other mentioned, I reset the trip and that is my gas gage most of the time. Even on day trips, 100 miles for me and I need a stretch anyway. My gage works correctly and the light comes on at about a gallon left. Only reason I know is I checked. Other bike is carb and only has a reserve. After reaching down a few times to turn reserve on, I knew I did not want to do that silliness running out of gas with idiot cagers tailgating me ever again. I fill up ever 100 miles. Not big deal for me however. Son's bike is newer and does not work period.

The stock gauge is notoriously inaccurate anyway.
I changed my speedo for a new analog one from HD
(Combination Analog Speedometer/Tachometer, 5" - Spun Aluminum Dial - p/n 74774-11)
That one is far more accurate... When the stock gauge pegs at "E", the new one says 1/4 tank left, which is right.
