I've noticed that when I fill up the tank then ride around the meter tends to go from full to about 90% at a reasonable rate, then I'll take a short ride, like just up to the party store and back, which can't be more than two miles total, and when I get back it's down to just over half full, like maybe some screw is lose or something. I'm not sure if I can trust it. Is there any way to check that the gauge is functioning properly?
My first thought is to drain the gas somewhere, then plug the tank and fill it with water, let the water out and watch the gauge to see if it jumps
Faulty Fuel Gage?

Drain the tank then add gas a cup at a time. See what the gauge does. These aren't terrably accurate but once you figure it out it should be consistant from tank to tank.

Let's give it a try, how hard could it be?

Ok, I bothered to pay attention while refueling just now
I don't know how much gas was in the tank but I put over a gallon in, and it was only a gallon tank.
At about half a gallon the meter registered more than no gas
At about 90% of a gallon it registered totally full
So how do I reset the meter to read properly?
Other than where the display is does the meter on an SB vary much from other models?

If the bike is an SB50 its not electrical at all. Its just a mechanical gauge with a solid foam float at the end of a plastic rod. You won't be able to change the range it covers, but could adjust where it zeros by heating and gently bending the rod. Personally, I don't think its worth it - its not very accurate anyway and you will probably not get a good seal again when you re-attach the gauge window (its below the fuel level at full).Kenny_McCormic wrote:It is a stepper sender, not linear or anything. Ru it empty and see what it reads.
