I have a 2004 Foreman 450ES with swamp lite tires? What kind of carb kit do I need?What about a Dyno kit? Where do you get it and how much?? Is it hard to do? It hesitates alot now and I have a jet or something in it that came with my HMF exhaust. I don't know anything about a carb, so I don't know if I put it in right or not.
