I am really happy with my 02 BigBear 2x4x4. However it would be even more fun with a bigger engine. I dont want to internally modify the stocker.Has anybody swapped engines with driveshafts? Ive done 2 pickups and a car, but never an ATV.

 

I've never heard of it being done to an ATV. On car's its different because you can get just about any engine to bolt up to any bellhousing as long as you have adaptors. With ATV's you dont have that. I think it'd be nearly impossible to do this. Unless you have a lot of time and a lot of money, your better off buying a larger machine.
