Never had this happen before. No oil leaks, everything looks dry as a bone around the oil filter, drain and hub oil drain. I overfilled the gas a bit to the top and noticed this small (silver dollar) sized liquid/oil stain on the ground next to the Vespa (by the muffler) It smelled like gas but had a reddish tint.

Any ideas what this might be? Defiantly not motor oil. Think it's from the overfill?

The liquid had more of an oily consistency than fuel consistency but smelled gassy.

Never seen this before, but seemed to occur an hour or so after the full top-up of gas.

If it smells like fuel, happened when some fuel spilled, and is located near the scene of the spill, why overthink the situation? The spilled fuel probably dissolved some stuff as it dribbled down and ended on the garage floor. NBD.

I didn't spill the fuel, I just filled it up all the way to the top. Nothing has reappeared, so I'm not worried about it anymore

Mystery spots under vehicles can always be nerve-wracking. Have you taken it out for a spin since noticing the stain?

If you cannot replicate the liquid spot after a ride and everything looks dry around the various engine parts, I'd agree that it's nothing to worry about.

Yes, you did spill fuel, into the evap system cannister if you filled to the top of the neck. Perhaps there is a small leak from that.

That's exactly what I was thinking. It rides just fine and has no more leaky spots so hopefully we're good
