I am going to be getting into the engine of my 07 wr450, and If I'm going to do any little hop ups, now is the time. I'm curious about how yz cams work with e start, how hot cams work with the e start, and how higher compression pistons work with the e start. I am in no way willing to part with my magic button. I love it. Ideally I want a bike that grunts like a wr down low, but will rev out well like a yz. I'm not really looking for a ton more power, or a setup that is too finicky. I love the reliability of my bike and don't want to sacrifice too much of the durability of the stock setup. Let me know what has worked for you guys and what hasn't. Thanks.
