I have a warranty. The thing is that the dealership decided they don't even need to un-bolt and change the gasket. They decided to just re-torque bolts without changing the gasket. Right now, my warranty will be gone soon (December). I guess I told them that if it leaks again, hopefully they can re-torque it with a new gasket, maybe for free, because they decided to go the cheap way the first time. So it is a little worrying, frankly.
The issue was, that they told me, some bolts on this top cover could be undone by hand. In a way, some bolts didn't press the cover at all, there was no torque downwards pressure at all. So, when the engine revved high, it is likely was spilling oil through those badly clamped areas.
I recognized my leak because I seen someone post the same thing, telling it was the top cover issue. Maybe our bikes were all done by the same poorly trained assembly person.
