I think running that crankcase breather into the snorkel could cause some problems for ya, you might want to just extend that hose and run it alongside the snorkel up to the top. The big problem I see with it is that you're going to have a lot of airflow restriction with that little 1" snorkel pipe, which is going to create a bunch of vacuum in that part of the intake. That's bad, you want the crankcase vented to atmospheric pressure or your engine is actually going to be sucking a bunch of air (and likely a bunch of oil) out of your crankcase and through your intake. It would be a pretty simple fix, just wanted to bring that to your attention now before you start running into problems later with your oil disappearing and it smoking like a mofo. Just put a nipple-nipple hose adapter on there and extend the breather alongside the snorkel, and put a crankcase breather filter on the end of it, problem solved.
You do realize that thing is going to be ridiculously restrictive, right? I bet that thing drops 5 hp or more off the top. If I was going to do a snorkel setup on a warrior, personally I would have kept the stock airbox, sealed the lid, and drilled a hole in the underside of the box for the snorkel pipe. That might allow enough room to run 2" pipe all the way which is a lot less restrictive, keeping the airbox would also eliminate the need for a filter at the top of the pipe, and you can even take the airbox lid off when you're not going to be getting wet so you can get your power back.
