250r powervalve in a 400EX??

[Bigg Pimpin]

Anyone got experience putting a CR250R engine in a 400EX? Besides needing a forward kick what else will be needed? I am sure the motor mounts and such will have to be fabbed up but besides that how hard will it really be. Doesn't seem like it would be that difficult to me but I could be wrong. Thanks

the frame needs to be painted wit some special paint for less vibration or something like that.
