Gas Gauge Problem
I tried a search but didn't find anything. The other day I was ridding and noticed that the gas gauge was at half a tank but when i rolled the throtle in gear the gas gauge would go down to a quarter or less. When I was at a stand still gas gauge went to normal and when I rolled throttle with clutch in it didn't move. Only jumps down when in gear and rolling throttle. I'm not sure if I'm losing power at all,it's one of those things where you go " was it always like this ". It's an 07 Roadglide, im going to Americade and just wanna make sure it's nothing serious, I called dealer and they said it might be resistor.

The gas tank level is measured by a float inside the tank, part of a device that is connected electrically to the gas guage. It is mounted offset in one side of your tank. You may find that when going round bends the level will change, also when the bike is on the jiffy stand. When you sit on the bike and lift it upright it will change again, which is when it is at its most accurate.
If the level drops when parked on the jiffy, when compared with bike upright, you know the float is in the righthand side of the tank! If the reverse happens, the float is in the left. Hope that helps you decide if all is well!

My gas gauge started acting funky a couple years ago, doing the same thing others had described over the years. Now I just keep it full, and ignore the gauge. I lived w/o a gauge for many years before, so will be OK w/o an accurate one now.

The gauge on my '09 works pretty good but I have never trusted any gas gauge on any bike. I use the Tripometer and always have. Never failed me yet.

You will get different readings depending on what the bike is doing, uphill, downhill, slowing down, speeding up etc. That said, the gauge processes the info from the unit in the tank and that processing can get out of whack if the gauge stops processing properly. Had mine replace under warrantee as I was getting all sorts of strange readings. But they are never accurate, the only thing any gas gauge tells you for sure it that you have a gas gauge.
