Well, we all know what happens when you assume...

Thanks Jay for your input as well. I do have a set of extra set of bone stock carbs for a newgen that I know work great and before I go back to logical square 1, I'm going to swap the jet kit over to that set and give it a shot.
I might put that set on, as is, and see what you get before swapping jets.

Danno would know better, but I didn't think it would run terrible with the stock jetting and your set-up. Not perfect, but decent. You could also just put the snorkel and stock air filter in while you are at it for testing purposes - if you wanted to get closer to Square 1.
