You must not know anything about scooters or auto mechanics to ask that. First off, for example A 50cc scooter, is a scooter with an engine that is 50cc, which is roughly a cube that is 50 centimeter's on all of its sides., rougly. You can't make the engine bigger, nor can you turn it 'UP' or Raise it. There are claims of making it bigger but you can't. In actuality of what is going on, is that they are increasing the power it puts out by replacing other parts like the carburetor and rejetting it, the scooter's computer, and other parts to make it push out as much power as bigger sized engines do.
Say someone says that they had a 50cc scooter and made it goto 60-70cc, what that really means is that they either replaced the engine with a 60 or 70cc engine, or they changed the stock/OEM parts that came with the bike with high performance parts excluding the engine itself and made it as powerful as a 60cc or 70cc scooter.
That's all it means.
I hope this helps you in your quest to making your bike stronger mate.

One last thing as well, an engine is an engine, a 50cc engine is an 50cc engine, it creates 0 horsepower, but depending on how you tune it and tweak it, if you know how and how you modify it, will determine how much you get out of it. With most cheap setups and stock setups, you'll get about 3 horses out of it, but with enough tweaking and aftermarket parts, you can get 5-6 horses out of it, which is the same as a 100cc scooter, but I'm sure the parts and the money to pay someone to tune out your engine to do that costs more than a new 100/150/and even 200cc bikes. However if you are from south America or some parts of Europe, this isn't a bad thing as you can still legally enter into races that are limted to only 50cc engines. and take out the competition
If you could raise your CC's, then there would be no such thing as engine swapping for cars, as that is a really really big part of the car mod industry. As car's engines are also in CC's as well, but only a true car enthusiast would be interested in that. So now you know, CC's is the measurement size of an engine's displacement, not the power you get. anyway goodluck mate!
