Then you repair and re-weld it.
Or... or... just hear me out here...
Since you'd have the entire thing basically stripped to a bare frame anyhow, how about going through each of the frame weld points and inspecting them, rewelding as needed, and adding bracing where identified weak points exist.
Just because you have 40hp in a bike frame doesn't mean all 40 horsies are being applied at any given time either.
Hell, even on a stock bike, unless you're going WOT up to 8000rpm on every ride, you're not even using all 15-16hp there either.
Anyone capable of stuffing an EX250f engine into a cheap XR clone frame is certainly capable of reinforcing and ensuring the frame is able to handle it.
