2012 yfz Carb Jetting

I've been looking to the yfz forums for a few weeks now looking through old topics for advice but I'm new to both the forum and yfz's. I bought a new to me yfz 450 about a week ago. I was told it was a 2008 but when I took it to my girlfriend's dad who knows quite a bit more than me about them he told me it was a 2012. I'm trying to figure out what kind of jetting I need for the setup I'm running. 2012 yfz 450 with hmf competition exhaust, uni air filter, and an open air box. At the moment my header pipe glows red and it backfires quite a bit and I think it's running way too lean. I'm looking to get a jet kit and I need some advice on what to buy. Any help is very appreciated!
