Gas gauge issues

[Gary N.]

Having some issues with my gas gauge on the '06. It all seems to have started after my last trip when I had the magnetic tank bag attached but that just might be a coincidence. Never had an issue with the tank bag on the '03.
The gauge won't show full anymore, always one bar down and after about 50 miles or so it reads all over the map. Some times no bars will show at all and some times it will read anywhere from nothing to 3/4. The low fuel light and count down meter seem to be still working but I don't trust it.
Had to start using the reserve valve again just in case.
I don't remember reading about anyone having issues with the gas gauge before.
My have to go for my first warranty job on this bike.

Reboot. Oops not a computer.. well kinda... Pull the Battery Leads for a few minutes then reconnect this might straighten out it brains like a reboot on the onboard PC.

Good Luck

Mine did that a couple of times, I unplugged the connection at the tank and cleaned the connectors and put some dielectic grease on it and it hasn't happened again.

Gary, mine did something similar about 5 years ago. There is some sort of sensor or sending unit under the tank that goes bad. The dealer replaced that along with a new dash panel because he said the gas gauge was bad too. The gas gauge is part of that panel and cannot be seperated so basically I got a whole new dash under warranty.

Seems like it's working OK again. The dielectric grease in the connector has made a difference. I need to run a couple of tanks of gas to be sure.

I had that problem at 24,000 mi or so. Replaced under warranty and got 00000 on the odo after I got it back. Rod

Well I haven't been riding as much as normal this year but I finally think I've got the gas gauge problem solved. I tried the easy fix first and it worked. Greased up the connector and everything is back to normal.

Terrific! Thanks for the update :)
