Crazy though,t 250cc in a razz

[125ccrazz]

So i picked up a 250cc buggy motor the other day, came from a rocketa,liquid cooled 4 stroke.
And i really would love to put it in my razz. But i need help finding parts or maybe just it just can't be done.
i would think they are very similar, if not the same as in 250cc scooters. Right now the motor just has a output shaft that went to a transmission.

Can i just put an output shaft from a scooter ?

Thoughts? Feedback ? ideas for parts?
