    Pull the sending unit out and check the magnet, they come loose, just need to re-glue it. If that is what it is, it is an easy fix.

    Sending unit is under the Gauge panel, left side. Don't remove it with a full tank of gas or it'll spill! Drain it down to about 1/2 tank first.

    My gauge quit working too. Im off to get the superglue to reinstall the magnet. For a while I was filling up by keeping track of milage. Generally 220 (130 miles ) to 240 (145 miles ) between fills. Thats not always a good way of doing things as it turns out. My calculations were for cruising at 70 mph aprox. Not 85 mph into a strong headwind. Drained her at 190 115 miles about 5 hour ride from home. Got a ride with the first car that went by to a gas station and on the way back I was at the highway helmet and gas can in hand, and a guy in a pickup with a dirtbike in the back went right by. Was I ticked. 2nd car gave me a ride back to the bike and I was away. Got to Calgary ( 7 hours from moosejaw ) and got a call from my partner in moosejaw wondering why my bike was on the side of the road. Turns out a Greyhound bus driver that knows my bike saw it on the highway and called him to see what was up. Hard to be invisible here.

    AFA the gas gage, mine also was sticking then jumped at least 1/8 of a tank each time. I have smoothed it out some with help from the forum. Get some sandpaper and gently smooth out the 2 front edges and the round shaped back side. I took a look at the receiving unit inside the tube and saw that that were pickups every 1/8 tank all the way down the tube, thus the reason for the gage dropping 1/8 each time. When reinserting the float and the magnet remember that the magnet goes up. Ask me sometime how I figured that one out.

    Well, my bike's gas gauge left me dry on the side of the road today.
    I was on my way to participate in a Patriot Guard Riders mission
    about 150 miles away. Bike sputtered and quit.
    I figured the fuel filter was plugged, as my gas gauge showed about
    1/4 tank of gas left. I think I will replace the fuel filter.
    Thank goodness I was only 7 miles away from home, and have a super
    next-door neighbor who also rides. He brought some gas, we put it
    in, and I drove it home. Started right up!
    As I have been reading ya'll's posts on the issue, I will try to tackle
    this when I run my gas tank down to less than half(thanks Don!),
    as I just filled it up.
    I have read your posts about the magnet, the float, sanding the float,
    cleaning it with fresh gas, and reinstalling. I appreciate you guys
    having had some experience with this, as I am sure it will help me out.
    I will fill you guys in on how it goes in a couple of weeks, after I get home
    from my family vaction/holiday.

    Bill

    P.S. As my next-door neighbor(Jerry) has been drooling about some
    bike "things" I have on my bike, I have just ordered those items
    to be sent to him next week while I am on vacation.

    Let this be a lesson to all of you. Never trust the gage. I always go by miles travelled.

    Well, I have my gas gauge sending unit apart.

    Reglued the magnet. (Waiting 24 hours to reinstall)
    Will inform ya'll if I am successful or not sometime
    late this weekend.....

    Well, my gauge quit also last week, after 46,000 miles. But I removed the sending unit, and there was that magnet...it had came off as said here. Cleaned, reglued with Super Glue, and works great now...all total, about 10 minutes work from the start to finish. I honestly believe that this problem is connected with so many problems I hear of from local auto dealers...ethanol in the gasoline. It is simply an alcohol, and it does not like glues, adhesives, or rubber lines, and plastic/rubber components at all. I am told that since the introduction of ethanol into the gasoline supply system, the auto dealers have been inundated with customer conplaints. They range from check engine lights, plugged fuel injectors, slivers of rubber etc. in the fuel systems causing a few major problems. It is harder and harder to locate stations that do not sell gas with ethanol, but we still have one here in our area. I think that by 2012 all gas has to have it in it. Another situation of government intervention...

    Excuse the dumb question - any way to know where you can still buy gas without ethanol? Does it go by state, or by gas station brand? Thanks!

    Don't buy it in Missouri if you don't want ethanol, all gas contains 10% since January.

    Well it happened to me today. My gas gauge was reading 1/2 full and all of a sudden I sputtered dead to the side of the road. Assuming the fuel pump took a dump I took the top seat panel off and checked the clear glass fuel filter I have in line between the petcock and fuel pump (I also have another clear glass filter between the pump and carb so I can monitor fuel flow all around - thanks Jack lol) and noticed it was empty. Then I looked in the gas tank and saw it was bone dry. Well anyway after waiting on the side of the open stretch of desolate road I was on for a about a half hour while several so-called douche-bag bikers drove right by like I was fkn invisible 2 righteous dudes with their girlfriends on Harleys stopped and drove to the nearest gas station and brought back 3 gallons of fresh Premium in a borrowed container and I was on my way. The dudes refused to accept a dime from me too. They just said for me to help them if/when the time ever came. I was very appreciative and we went our seperate ways. Well it's off now to take out the sending unit and repair whatever's wrong .

    I just took my sending unit apart and sure enough the magnet had detached from the foam float. I'm not so sure however that Super Glue is the correct adhesive to use to make the repair. I called the tech people at SuperGlue.com and they told me super glue will not hold up over time immersed in gasoline as it's not made for that application. But then again if the magnet is glued to the top of the foam and the foam is floating on the gas the magnet may never actually be in the gas. I may just use a little bit of 2 part liquid epoxy.

    Sonny,

    I used 2-part liquid epoxy.
    Waited 24 hours, then reassembled
    and reinstalled the unit.
    So far, so good!

    Yep that's what I just did. Should be ok. Now I'm curious to know what glue is originally used and why some magnets become detached to begin with. But anyway I like easy simple fixes :D which leaves me more time for this :beer8: .

    My gas guage stopped working too. I put some fuel in and it went to 3/4 full and stayed there. When I fueled again later, I filled it up and it went to full as I expected. Unfortunately, it stayed at full and hasn't moved. It sounds like the same problem, but I am not sure. Any thoughts?

    Also, I don't know how to fix it, but I am trainable. What do I need to take off and how do I access it? (Step by step like you're talking to an amateur please.)

    Thanks Guys,

    BD,
    Take your instrument panel off by taking out the two long bottom screws. Lift off and you will see on the left the round fuel sending unit (3 screws hold in). Note the orientation, remove and you'll notice at the bottom of the tube that there are screws to remove and the bottom comes out. You then access the float and magnet. Again...note the orientation. Fix and re-assemble in reverse order.

    This has been discussed before but I wouldn't use Super Glue. Their tech line people say it is not fuel proof and will eventually break down in that environment. If you are going to bother fixing it you might as well do it the right way and use a good 2 part epoxy. Just my .02

    Hey Matt,

    Thanks for the direction on fixing the gas gauge. I followed your instructions and it turned out to be an easy fix. The magnet was off and after I glued it, fuel gauge worked fine.

    Thanks again, I have to admit it felt pretty good to fix it myself.

    Default fuel gage

    Does the magnet go in the groove? Seems like yal never mentioned that particular part of the equation!! Or does it simply lay flat on the top of the float?

    Jim

    somebody just call me please.. that will work much better and much quiker.. Thank you,
