My 2003 Nighthawk 750 gets stuck floats if I leave it for more than a week without riding it. I've had the carbs rebuilt and synchronized, and I switched to ethanol-free fuel, but it remains to be an issue. It just demands to be ridden at least once a week.
To resolve the issue, I suggest dumping a can of Seafoam or other carb cleaner in the tank after siphoning as much old fuel out as possible and then top it off with fresh fuel. Then tap the carbs with a screwdriver handle to see if you can free the stuck floats. If none of that helps, the surefire way I've gotten the floats unstuck is to strap the motorcycle to a trailer and take it for a drive. All the bounding around helps free up the floats. Your only other option is to ride it, putting fresh clean fuel in the tank as often as possible. The dripping gas seems dangerous, but when it happens to my bike, it only drips gas at idle. With the throttle open, it seems to stop dripping gas. On Tuesday, March 21, 2017 at 4:01:37 PM UTC-4, Keith Meier wrote: > > Was thinking about picking up another Nighthawk.
