is it possible to mod a 100cc engine on a 70cc dirt bike?

It's possible, I put a 125cc on a 50cc it took some work but thats because 125 is alot larger than the 50. You might not even have to make any mods to the 70cc frame. 100cc motor isnt much bigger than the 70cc.

You want to ask this question in the motorcycle section. This is for bicycles and you will get lame answers like Eric's.
