Dida search for this and came up with a bunch of "check the dry break" answers, but I don't think this is my problem. Here's the situation. Low fuel light comes on and goes off randomly. Yesterday, went on a ride of about 165 miles. Low fuel light was on when I started, so I stopped and filled up. Only took about 1.5 gallons. I went on the ride and after about 50 miles the light came on. I knew I had plenty of gas and suspected the dry breaks, so I just kept my eye on it. No sputtering, engine continued to run fine. Stopped and had lunch at about 80 miles. Got back on the bike and the low fuel light was out. I went about 10 miles and the low fuel light came back on. Stopped for gas at about 100 (took only 1.5 gals to fill up!) and the fuel light was still on. Rode the rest of the way home, about 65 miles with no problems, except the light. So, it is obvious to me that plenty of fuel is getting from the main tank to the reserve. Does anyone know how the low fuel sensor works? Is it some kind of float or other kind of sensor. Do they go bad? Is there any record of connector problems? I am very open to suggestions at this point.
