Ok, 1998 VFR 800, for some reason when i top the bike right up (nearly over flowing)the fuel gauge seems to not work properly, it reads only 3/4 when full and will continue to read wrong untill i run the tank 1/2 emptyish then top it up again (but not 100% full). but then some times it works fine ??????? I've had the sender out, chacked all conections, shook it, tapped it, etc, etc but no luck.
