I've rode with Jason for a few years now. Pretty straight forward riding, and regular maintenance. This is just bad luck... Jason, I think you did some self-tuning on the juice box. Take it back to a factory default. Maybe it was dumping to much fuel. If you can't find the stock exhaust, maybe factory settings will fly at the dealer. I'm sure someone here knows a Yamaha mechanic. My years in the business, it usually came down to the tech saying it's abuse. With an advanced call to that tech and a case of beer you might be golden to get the work done at that shop under warranty without pulling the parts. Couldn't hurt to ask...
