Hey can anyone tell me what the stock front sprocket size is for a 00' 400ex? I think the one on mine is aftermarket or has been replaced since the bolts holding it in look newer. And whats the stock chain size? Mines got too much slack and its been adjusted all the way. Thinking about dropping down a tooth size in the front to get a lil more bottom end pep but not too sure.
