Make them fix it. You paid for a working and relatively accurate fuel gauge, make them fix it. My fuel gauge does not flux and is relatively accurate. Like a number of other folks said, keep a track on your mileage.

I have no bouncing at all. It goes all the way down to "E"..stays rock solid and I have about a half gallon left.

I'm starting to thing my gauge or float or whatever is worth MONEY with all the posts about fubared gauges....LOL No problems here....

And let me add that if mine did bounce around like a loose hand of a clock I wouldnt accept them telling me it's normal. Because they have a problem with gauges aint my problem. They would Fix it because I would be a relentless PIA to them and they make alot of $$ off me in other stuff and they know that so they wouldnt be so quick to tell me to go screw off....Have them fix it.

As far as the rest of the antiquated float, sending unit and gauge are concerned - well that's another story.

I agree and think the OP's gauge, float, etc. are all operating properly. OTOH it's hard to determine for sure without actually watching it. One thing for sure, and this hasn't been verified that I know of, if the OP's gauge is fluctuating while he's moving at a consistent speed that isn't normal behavior, IMO. Mine will fluctuate upon acceleration and deceleration, how much depending on the inertia delivered. I use the gauge as a guide but don't trust it past about ¼-tank, although I do find the warning light to be fairly consistent at notifying me that I have about one gallon of gas remaining. When it comes on I look at the odometer and add the number of miles I think I have based on the conditions, but I don't stretch it to the last few miles. I don't trust it that much, and when the light comes on I start looking for a gas station. I also have learned that certain graduations on the gauge are fairly accurate indicators of how much gas has been consumed. I can usually guess how much gas will go in to fill the tank within 0.2 gallons based on the gauge.

Even with its weaknesses, I rely on both the gauge and miles traveled equally, as my gas mileage varies wildly depending on conditions, as much as 15mpg. I can do the math based on my experience with the bike and about what gas mileage I know I'm getting, but I use the gauge as much for determining how much gas I have remaining.
