You will spend close to $550-600 when all said and done on bigger carbs. Gotta remember your gonna need selection of jets/needles, cable, filters, outerwears, etc.. plus what you already said. You can get them all from the same place and save shipping if you look around too. If you want to wait a couple of weeks we are going to be running some Holiday specials that should be worth the wait $$$$$!!! :biggrin:
