I would first check the connections under your seat where they come off the tank. These bullet connectors are known for bad connections.

Absolutely, check the bullet connectors. But also, are you sure the fuel gauge sending unit (in the tank) even has a float? That was my problem.

I used this awesome thread (thanks to Jethro) to fix mine about two years ago. http://www.thegsresources.com/_forum...e+sending+unit

Know that even if you have a float, your pickup could be loose and not connecting with the pickup coil, or it is milaligned and outside the range. Read this thread it'll really help you out. It's the first thing I did, and I was mechanically retarded.

Also from that thread in a later post "The system works on resistance, the more the resistance the lower the reading on the fuel gage. Lower the resistance and the needle moves towards full, when the wiper arm moves it changes the resistance output." I'm not sure what the resistance range should be, but you will need a multimeter to check the resistance as you manually raise and lower the float. That will help you make sure that the blade is in the right range of the coil.

It's really less complicated than I'm making it out to be, honest.

Leak?

I've had gas gas gauge problems in the past and worked through all of them, successfully, and agree with all of the above comments. Now.....

This is purely a guess. If the tank showed full when you filled it but quickly went to the empty spot on the dial, I would guess, maybe, the float has a hole in it and it filled up with gas after you filled it. That guess is based on little information since I don't know how much gas was in it to start with or where the dial was to start with.

Good point chucky.... I hadn't even noticed that it did work. If it worked as some point, you most likely have a float lol. Though the resistance readings could certainly be off, or it could be a problem with the float.

To add to my post, if this hadn't been a situation where the gauge worked at some point, one thing you'd also want to do is use a paperclip or something to bridge the bullet connectors on the gauge sie (not the tank side). Once bridged, the fuel level on the handlebars should start to rise to the top, and once the bridge is removed it should fall back to empty.

Thanks, guys. Based on this info, it sounds suspiciously like a float problem.

When I got the bike, it had about half a tank. When I filled it up, it read full. Then somewhere down the road it read Empty. I'll let you know what happens once I get some riding in and get around to it later this season. I can live with it for a while to get some miles in on the new machine! \\

Well, based on that, I now think there's a good chance that your connection between the tank and seat are loose (as Bill said). I hope so because that's a really easy fix.

If it's not that, you're going to have to consider JC's advice and check it out that way. It must be one or the other because I don't think your float has a hole in it. Let us know!

Who needs a gas gauge ? Mine has never worked.
