fuel gauage stuck on full fuel gauage goes to full and stays
Several things could be causing this. Make sure the connections under the tank are ok. The fuel sender inside the tank could be bad. The float could be stuck on the side of the tank. Sometimes this happens on early 2000's bikes. I the float is stuck, you have to go into the tank and bend it away slightly from the side of the tank.

Many bikes have had this problem and here's the fix...
Check the float in the tank. They are known for hanging up. You will have to bend the arm in a way that repositions the float away from the tank and the hoses around the unit (not up or down) but sideways. Bending it up or down will change the readings on the gauge and make it inaccurate. You have to pull the panel on top of the tank to do this. Just remember to replace the screws and gasket when you do this, they are self sealing and cannot be reused safely. If not that , then here's a post that will give you the parameters for testing the sending unit.
hopes this helps ya.
