I had that same problem with mine for a few days this spring. Turned the key and they cycled fine. Started the bike and the fuel gauged pegged and stayed there. The Tach was also reading low. Tried turing the bike off and back on right away, the fuel gause did not cycle properly. After riding a couple of miles, I turned the bike off and back on and everything was normal again. This went on for a few days, I'd just turn the bike off and back on after a mile or so. Figured I'd look at it over the weekend, but after a couple of days, everything went back to normal. Never had a chance to find out what the cause was.
