Sled motor in a polaris atv?

[trimoto.125]

Hi I was just wondering how hard it woul be to put a snowmobile motor in a belt driven polaris atv. Also will a rotax 340 f/c motor be enough and will it overheat?

I have seen videos of a guy that put a 800cc sled motor in a 2x4 scrambler, it was insane.

if you go for it, i would change the pully ratio on the fan so it spins faster, and fabricate a good sized air shroud to feed it. I have a 340 kohler in a 225dx frame with a good sized shroud and it runs much better just after the sun sets than it does during the 85-90* day.

I was thinking about putting a skidoo blizzard 9500+ motor in one but now im kinda leaning towards an odysee frame
