To start my GPZ 550 I have to use starting fluid. As long as I spray starting fluid into the carbs the bike will run. As soon as i stop sraying the bike dies. I took the carb apart and can´t find nothing wrong. I know the carbs are getting gas from the tank because I checked that. My question is how does the gas move from the fuel bowls and into the motor. The bike will not even try to start when I use gas. I just bought the bike last week so I´m learning about it.Thanks
