Bike wouldn't start this morning. I loosened the side panels and slid the tank back, then propped it up vertically to check for kinked lines. No kinks. I pushed on all the connectors, and everything was properly seated. I tapped on the fuel filter. I sat the tank back down, turned the ignition on, and it started immediately.
So, I'm thinking this is a fueling issue. Either the injector or the fuel pump... but I'm leaning towards the fuel pump. I've read that the sock can deteriorate when a bike sits for a long time with the same fuel in it, and then it gets sucked into the pump and clogs it up. And this bike did sit a lot before I bought it from you. I'm betting that sloshing the fuel around and upending the tank is what allowed the bike to start. I'm going to get a siphon pump to drain the fuel out and then remove the tank and inspect the fuel pump to see if the sock is present and accounted for.
I'm not sure how a fueling issue can cause my catalyst to burn out, but if the whole problem is a faulty fuel pump I will be THRILLED. Easy and cheap to fix.

Well, it did sit idle for a while but I'd start it once in a while to let it warm up. I noticed if I let it sit up for a few weeks then start it the pump would make a light squawking sound but after warming up it and starting it again it wouldn't make that noise. Sounds like you might have found the problem. As far as the catalyst, maybe a partially blocked fuel filter would create a very lean condition and possibly superheat the catalyst? FI systems are a little bit of my mechanical knowledge range. A clogged injector wouldn't be out of the question, those holes are tiny.
