gas leak

[Orange-65]

I have a gas leak coming out of the drain tube front left next to radiator. Leak only occurs when bike is running. It is an 05 RSV. I have taken the quad carbs completely off, cleaned all the floats and needles....Put it all back together and was going for a ride but again the leak......Any thoughts????

Sounds like the drain screw isn't seated either by grit or damage?

I cleaned all the bowls, needles, ckecked all floats, reasembled and put back on. It only leaks if the motor is running....Could it be a pump problem?

I don't believe the bowls get 'pressurized' by the pump, when the bowl float raises and shuts off the flow the pump stops. When running you have fuel flow, vibration and probably upright to get the leak?

You are leaning toward a float or trash on a needle being the prob????
