Fuel Gauge not accurate? Road King Classic
Last year I purchased a 1996 Road King Classic. Its got the fuel gauge right on the tank obviously because it does not have a fairing. However, since purchasing it I've had an annoying problem thats driving me nuts! After about 50 miles, the low fuel light comes on, and obviously stays on.. Also, it shows about half a tank left after using a little over a gallon of gas. Just to test, I drained the tank and refilled it, after nearly 2.5 gallons the tank was barely off empty.
So I pulled out the fuel float assembly, bent it down, and was able to get a more accurate fuel reading from the needle. However the gas light still came on at about 75 miles. So one day at the dealer I asked them how much a replacement fuel float assembly was, and it was about $35.. What the heck, mine is obviously 10 years old, maybe its just worn out. So I bought it.
Today I put the new one in, and its back to how it originally was.. I need to put in 2.5-3 gallons to just get the needle MAYBE up to 1/4 full. After about 4.5 gallons it was up to a little over half. Put about 5.1 gallons in and its still not up to full. The fuel light didn't go out until after about 4 gallons of gas were put in.
Ok, so does anyone understand what the problem is? I can't imagine they intend the fuel light to come on after 1 to 1.5 gallons are used.. I would think it would be the opposite, maybe 1 to 1.5 gallons it would come ON. I guess I could just bend the float down again, and that would get my needle more accurate, but I want to FIX it..
So I guess my only other option is the actual fuel gauge itself? Although I imagine thats probably in the $50-100 range just for the part.. and its probably not worth it unless I would KNOW it would fix the problem. The other thing it could be is just a defective design, but I guess others in here would be complaining about it.
I'm curious if anyone has any opinions or experience with this. I can only assume that the fuel light comes on when the float hits a certain level, and if mine is coming on early its because the gauge is defective or the float is way off. I'm perplexed.. If anyone has a fuel gauge off a model that may be compatible I guess I would be willing to buy it off you (like from a wrecked bike or someone who bought a different style.)
Any ideas would be appreciated.

RE: Fuel Gauge not accurate? Road King Classic
Wait a minute, we have fuel indicators on our bikes! Say it isn't so!!!
Mine is actually fairly accurate, but it does the 'stay on F forever, then drop like a rock' routine. The light comes on (FI bike) about 170 miles or so, and I've gone another 20 with no problems (so maybe 1/2 gallon was left when the light comes on). I know I can squeeze about 190-210 miles out of a tank, so I just watch the trip meter and judge it based on that.
