As Hoosier said, we're not there but, from what you're describing it really sounds like a fuel problem. Just for shits and giggles, check your pilot screws too. Make sure they're not screwed all the way in. If that's the case you won't be getting any fuel at all. Someone correct me if I'm wrong here but, I believe with the airbox, these should be about 3/4 turn out. Mine are 1 and 1/4 but I'm jetted. So often these problems end up being something silly that you don't think of.
Case in point, I was working on a CM400 for a customer the other day. He left then came back pushing the bike. Dies out on him. No spark. I went through EVERYTHING. Completely confused. Then just at random I disconnected the kill switch. Boom, she fired right up. Wires got pinched. So, just goes to show. Simple can be the biggest problem.
Good luck
It ain't a custom till you have customized it yourself.
