Is this real?

Is this a legit video? If so, what on earth has he done to this engine to get going this fast?

the answer is about a minute in. he sacrificed take off for top speed. there's nothing special done to it.

He geared it up a lot (smaller rear sprocket) and probably squeezed More horse power out of the engine. The bike looks on the lighter side also.

yeah he also has a pretty sweet looking pipe , you can really hear where it gets on the pipe

So if I get a really small rear sprocket, I can get over 40 mph easy along with some other performance mods on the engine?

with major modification, I still have room to accelerate at 40 with stock gearing. with a 36 tooth rear and bolt ons (expansion chamber, aftermarket head, maybe aftermarket carb) you should be able to hit 40 easily.
