petrol drip, gt550

[carlo]

Hi
After first time start up, this year, i found dripping of petrol underneath and back of swingarm, left side.
Is there a tube from carburator overflow inside? I have never seen that on picture or schema?
Thanks for answer

If it's the overflow then the flow should stop if the tap is in the "on" or "reserve" position. it should only leak when in the "prime" position and is probably a sticking or dirty needle valve. The overflow pipe runs from the carb down the back of the crankcase and out in front of the swing arm.

Thanks for answer.
I had just tryed to start up in prime position several times(before going to on position.)Then now I can see what happened.

Nice 550 Carlo. Can you post a better pic ? I would also highly suggest adding an inline filter, if you already don't have one. Like mentioned earlier, small rust particles will find their way to the needle valve. Build up there and prevent the needle valve from closing. Therefore, flooding and fuel leaks will occur. Or a leaking petcock.
