I was breaking my new motor in with the bike up on a stand and everything was going fine ..... all of a sudden it bogs and dies. I see fuel dumping out of the air filter so i turn it off and cleaned up the spilt gas. Then i started it again without turning the fuel back on. Ran fine until the bowl was empty so i turned the fuel back on and it started dumping out of the carb again. I did install a pulse fuel pump from an old briggs motor. Is it to strong maybe? The motor was smaller than mine so I doubt it. Any ideas would be appreciated...
