Hi Jay and welcome to the forum, I think you'll find that you need to change the pilots and the needles, I had a dynojet kit for my 4XV and the pilots had to be changed at the same time as the needles

No idea I'm afraid, I bought the kit but never had it fitted I'm afraid
As Jon said Al is the 4XV guru so he'll probably know

Welcome in Jay
to be honest i'm not going to be much help because personally i'd take it to a reputable rolling road & get it set up properly

as to your popping on decel mine pops on decel but not tickover ,just found this on allthingsmoto.com
"Most times a lean condition WILL be indicated by popping, but not always. TW"
"Any 4 stroke engine--even those that are flawlessly tuned will pop on decel. It is harmless, but can be annoying--granted. However, I would never alter the jetting of an otherwise performing motorcycle to get rid of it. Go by the seat of your pants and the color of your spark plug rather than the popping as an indication of the jetting of your scoot!"
Ok so the bike was a crosser but i think the theorys the same , heres the link
