how much improvement??
My dad just bought me a 2000 400ex and it already had an edlebrock quicksilver carb, pro circuit t-4 slip on, and a k&n air filter. I have never drove a stock ex so i have no room for comparison but i was just wondering how much of an horsepower increase those mods. made over stocksince i know a stock 1 has 27? thanks
