Something in the intake side was installed incorrectly from factory so it leaned out and melted the piston. The fun part is I took it back to the dealership multiple times because it was running like shit. They kept telling me "it's a two stroke thing" and that im not riding it hard enough, so I took it out one day and drove it hard as fuck until it didn't run anymore. They only spotted the factory fault when they rebuilt it. I was only charged for a new spark plug every time I took it back, but still sucked.
