China 230cc engine to crf250 conversion?

HI guys, i just bought a 09 crf250 frame & swingam was wanting to try fit the China 230cc in somehow,
I currently have the crf250 clone chasis, it's OK but it's heavy steel chassis, the Honda frame is soo much lighter so far i can see the bottom mounts maybe an issue, in know there is a crf450 with 230cc motor ,on here, want to try the 250 size 1st, if anyone has tried this let us know
Thanks

I tried to put a 230 OHC into a CRF250X frame, The Motor can be shoehorned in, but the shock is on the opposite side, so the "carb to airbox" is enough out of line, that I gave up on it.....

There are loads of variations of intake manifolds - looked at that? short on custom making it etc
