welcome, no not much in the 400 section, Nice looking 400. Looks like it has been taken care of. I have a 98 foreman 400, they are great bikes, just alittle shy on ground clearance. On the DJ kit, that is just the settings they got the best results from, so this gives you a good starting point. No two bikes are the same, so some adjustments will be needed. This is something that you are going to have play with to get it set right. On my 400 I'am running a 1.5" custom snorkel, stock exhaust and the factory OEM 130 jet. I just moved the needle to a richer setting and adjust the air/fuel mixture as needed.
Where was the crankcase line hooked up before? The crankcase vent will be fine running it up to the pod or along side of the snorkel. Just make sure to install some kind of filter on the end of it. Same for the carb. vent, pod or on snorkel.
You didn't list what size jet you where running, I assume a DJ126
As far as the hesitation, I would try moving the needle around to different settings. The needle is easy to move so I would try this first. Also try different setting on the air/fuel mixture, about 1/4 turns each try.
