Help a rookie out-84 big red

My girlfriends dad has a 84 Big Red, he bought new, it is like miont condition, all original. now he is old. So how can I tell what size the engine is?
It has reverse with low and hi range trans 4 spd autmatic.
Im not into ATV'S, im a sledhead, and gear head...trying to help a old man out.
He wants to sell it and buy something more stable like a smaller 4 wheeler.
So how can i find out engine size and value?

Thanks,
Carl

Well, does it say anything else on the machine? I'm guessing either a 125, 200, or 250...I know, but look around for numbers.

ATC70, ATC110, ATC125M, ATC200ES Big Red, ATC200M, ATC200S, ATC200x, ATC250R is what was available.

no allit says is BIG RED, it has a facvtory hitch and decals, gonna ake some pic s and post em
