Got home after a 50-ish mile ride today and after turning off the Vespa, it started making a weird, rhythmic moaning sound from the transmission area (check the video below for an audio sample). I'm no genius but this can't be good. Anyone have any ideas? Again, this is after the bike is completely off, keys removed. Thanks for any information.

The MV Wiki is actually full of useful stuff...

FAQ: Why does my GTS groan/moan/moo or fart when off?

Thanks so much for the link/info jimc! Good to know it's nothing serious. *whew*

Perhaps I should add the video to the wiki for future worriers!

Old thread but I found this happening on my GTS too... If I don't want to hear it I just loosen the gas cap and release the pressure, then retighten and go about my way...

It's just relieving pressure from the fuel tank through the evap system

Weird moaning sound coming from my Vespa
Hey I think that I live just down the road from you. I lost my cat a few days ago would you mind checking your pet carrier to see if she crawled in there? That may be the answer to your noise. 😳
