An inline gas filter is needed. If you have one it may need to be changed for a new one. Longer term, you may need to clean out your tank.
Best of success.

...What's the simplist way to resolve this problem? I'm guessing i will have to remove the carbs?
With engine running, rap smartly against the float bowl with a plastic mallet. This will often dislodge a speck of crud caught between the float needle and seat. If successful, would also drain the float bowl to hopefully flush out any remaining grit or crud.
Good Luck!

The technical term for that is "normal"...:laugh:Thank you for your response.I have replaced the petcock, and when its in the off position it stops leaking.
Most of them will seep if the petcock is left ON because gravity never stops pushing. The needle to brass seat is a metal to metal seal so some gas can seep by. If it leaks a lot quickly, you need to take the seat and needle out and polish the contact surfaces to make sure they are smooth. Or, buy new ones if they are available.

Thanks for all the advice guys, as far as how the dirt/rust might have got there, although I'm in a state of denial the tank does need to be cleaned and maybe por15? It looks like its just a cpl of patches of surface rust so I've just been ignoring it:blush:
Even if the tank is pristine, you will have a bunch of sediment and crud in the bottom of it because it is in the gas we buy. Take off the petcock and rinse the inside of the tank with some mineral spirits and get the crud out. Then clean the petcock and you should be good. Inline filters are always a good idea.

If you have a bit of crud between float seat and needle valve, you can remove the gas hose to the carbs and blow (kind of gently) with some compressed air and that will usually blow out the crud. If you want to go nuts, after ensuring that your tank isn't the source of crud and installing an inline filter, you can install a new needle seat assembly. I would suspect the accelerator pump check valve though... just from the fact that none of the other carbs are spewing. By the way, it isn't all that comforting to have gas overflow on a HOT engine. You might consider some hoses attached to the overflow barbs and routed over your swingarm.
