If the petcock is leaking there will be signs of that in the tray that surrounds the fuel filler. Also have a look at the overflow hoses under the bike.

If you look at #6 in the parts diagram, this is where mine was leaking.

It's a tube that feeds fuel from the accelerator pump to the nozzles at the top of the carbs. It has 2 o-rings on it that can leak, and is leaking on mine.

ah yup could be.. smelling fuel on a vehicle that uses Gasoline..
I'd be expecting to "see" liquid most time as well, when I smelled it..

like i said, my Petcock wasn't leaking liquid, but it was leaking vapors maybe..
it stopped doing that when I replaced it
You would think with a pressurized (4psi) that it would be leaking fuel but it wasn't

mrbelvedere,
Did you find your leak? I ask because this weekend I had the smell of gas when I went for a spin around the neighborhood ('94 GL1500). Found a trail of liquid on the rear cylinder head cover on the left side, but was unable to locate its source. I've removed most of the tupperware (including the air filter case), but I'm still not able to locate the source of the leak. My next step is to run the starter to see if I can see where it's spitting out. Strange thing is there's never been any puddles or spots under the bike.
Thanks.
