Looks pretty cool. Years ago my best friend bought a 250X that someone shoehorned an XR500 motor into. It ran strong and he could almost keep up with my 250R but he kept shearing the kickstarter shaft off and he sold it. I guess that was a known weak point on those engines, I wonder if that's why Mickey Dunlap used the 350X bottom end here.
