XR400 cam benefits

[Mitch400EX]

What are the benefits of running an XR400 cam? I've heard of people doing this a lot. But I've always thought the innards of the XR400 and 400EX motor were basically the same.

The XR400 cam is a little more aggresive than the stock 400ex cam,,and it's simple drop in part no additional mods necessary,,,,add the cam with a higher compression piston and you'll really wake up the beast...
