I just bought a 2012 LXV 150 ie with 82 miles. I've been riding it for a couple weeks and have about 300 miles on it. My engine overheated and began to stall. I haven't noticed a fan going on and was wondering if this is common. I also noticed that when it was shut off, the could hear it buzzing (like it was injecting gas). I opened the gas cap and it stopped. I did smell a lot of gas prior to that. I don't have the owners manual for this scooter.
This happened on my old 2006 GTS 200 as well.
