Just curious here. I have a 440 kit in the bike.. The carb is off a 450.. Why do we need to jet it up so much if it is coming off a bike that is a few CC bigger, in most cases makes more hp in stock trim then we make... Any good explanation on it??
So far(I know I will have to go bigger) I have the stock seconds in, a 190 main jet..
