well my engine for my 250 i just had built has died and ive had enough.

i am going to build a 250ex hybrid. im hoping a 400ex swing arm or 300ex will bolt up but i dont know.

engine wise i was thinking about a crf 250 i dont think i could squeeze a 450 in there.


any help would me much apreciated
