hey!!! I just realized how it happened!
when I got the bike the front brake wasn't working so I had it towed through AMA.
The tow company came with a flat bad track and they put the bike on the center stand and tied it down from the handlebars and the seat... during the transport we also had to stop because the bike was spinning!
I didn't make the connection immediately when the bike started leaking oil (9 days later).
I just called AMA to see if they have some kind of insurance to cover damages due to improper towing... they'll call me back in 24/48 hrs.
