650/X-2 Will my 650 crank work in a 750big pin motor ?

[650FLOWRIDA]

recently blew my 650 up and wanted to bore it out to 700 but instead i came across a really good deal on a 750big pin motor already bored out to an 800 with dual carbs. the 750 came with no crank, so i was wondering if i could just get away with using my 650 crank ??

people have told me that the only thing that are differnet are the strokes ? guess i better start shopping cranks then!
