I really need to give this a try. My fuel gauge is really funky and it doesn't act like I read of others. When I fill my tank, it shows full and stays there for a LONG time. My miles to empty shows a range of 489-490 miles. Both the range and the gauge come down, but not nearly as fast as reality should dictate. It is as if the bike thinks I have 3 extra gallons at all times.
Then, quite suddenly, the gauge will start working correctly for a few miles. The range drops back to reality and all is well for 5 to 10 minutes and then it goes right back to thinking I have 3 extra gallons again. Its the damnedest thing.
