I don't think that a 4 stroke.... look how low the carburetors sit on the back of the engine.
I swear that looks like a 350 air cooled twin 2 stroke of some sort with only little dump pipe on each cylinder instead of a tuned exhaust. Kawasaki made a Mach III 350 called the S2. Perhaps someone shoved a kawasaki street bike engine into a blaster frame...

I dont think it can be a 2 stroke judging by the sound and the fact is has a 4 inch exhaust... 2 strokes need the expansion chamber in the exhaust to run properly. I dunno, maybe you are right. Just a guess.
Guessing all the wiring hanging out might be EFI as well...
2 stroke doesn't have to have a tuned expansion chamber to run. It has to have a tuned expansion chamber to run WELL. LOL With a short "headpipe" the pressure wave is passing out into the air without being used to draw the old charge out or push the new charge back in.
Paulie, I think the "4 stroke sound" is simply expanding gasses coming out of a short piece of headpipe.
It looks like a kawasaki Mach II S2 engine shoehorned into a blaster frame.

X2 on SI it's not hadt to believe all the hinds of odd sized 4 and 2 cylinder streetbike motors people put into quad frames all I can say is I hope the frame is tough enough to handle all the weight from a 4 stroke motor.
That definitely sounds like a 2 stroke twin to me. Before expansion chambers were thought of the way you got a 2 stroke to breathe better, was to kinetically tune the header pipes.
Awwww it's a baby banshee 
Def carb not efi- I seen the carb haha
Also sic is right about the straight pipe. If your old enough and into r/c there was a time before expansion chambers.
'tuned' straight pipes were used. I used to run a tuned straight pipe on my 1/4 scale raco jackrabbit which can be seen on the quarterscale legends website (shameless self promotion)

I'm old enough, and cut my teeth on kinetically tuned "Villers" header pipes way prior to expansion chambers.
If I remember correctly to get the best out of a tuned header pipe an excessive amount of spark advance had to be used.
If you were slack with the kickstart and it fired early it would give you a sore leg and just about lift you over the handlebars.
