i got a gas leak on my girlfriends z400. it only leaks when i gets shook up over the bumps. the gas comes out of the bottom drian on the carb? does anyone have a reason as to why this may be. it runs great and does not run like its loadin up or gewttin flooded

 

It's coming out of the screw on the drain? Maybe the screw has come loose or the gasket is tired? N

 

check the gasket
