200x w/ 250R swingarm???

[Ridered916]

Hey guys Im new here so I dont know how many times this has been asked but does anyone know if the swingarm and shock from an 85, 86 atc 250r will fit an 84 200x? And has anyone heard of putting a 400ex engine in the 200x frame. Thanks for reading. Hope I get some promising answers

a 200x swingarm and frame is way to narrow for a R swingarm


and no a 400 wont fit
