Sometimes when I gas up and the tank is low I get a code that comes up on the odometer when I reset. It scrolls through Cal 01 to Cal 07. My Clymer Manual doesn't say anything about this. Anyone want to explain? I was hoping someone with a Harley manual for a 1999 Road King could help me out with this one. Not sure if I posted the code exactly as it appears in the post, but it's close. Thanks to anyone who can help.
