Early 1990's Suzuki Quadrunner 250 with Neon Green engine

Hi all, new member here. 

Picked up a really cheap non-runner last night from a neighbor. He had gotten it from someone else who had rebuilt it a few years ago and it has decorated his garage since.

It is an early-90's (1992 or 93?) Suzuki LT250, but the weird part is the engine is a neon green color. I am now wondering if someone swapped the original motor out of this quad. Does anyone have experience with these that could give me a pointer as to what this could have come out of? I have heard that some Arctic Cat models had the same Suzuki motor - could that be where this came from? It is a 2WD, and has the typical chain drive/RWD system with both front and rear (rear drum) brakes. Very little rust and mostly complete, for the price I paid it isn't bad, but I am not sure how to pinpoint the engine type, and I would like to have that figured out.

Just want to make sure what I am dealing with before ordering parts. I will need a carburetor by the looks of things, and air/oil/fuel filters, plugs, etc. 

Thanks in advance for any help, appreciate your experience with these quads.

Update: looks like the engine may have been painted green by a previous owner when it may have been in another bike. It turns out (after we deciphered the VIN) that this Suzuki quad is a 1985 (we were told 92 or 93) LT250E. The engine in the light of day looks a lot like a Suzuki engine despite the weird color. Now that I know it is an 85 I can proceed.
