by reducing weight of parts
That isn't always true. An engine with a larger displacement has an advantage but there are other factors that can increase power in a smaller engine that can out perform a larger engine.
You can increase the CCs of a bike by making sure the engine is working properly. Check the timing and gas consumption. You can also replace crank seals and valves to increase engine power.
Yes, it is possible to increase the cc of 100 cc to either 120 or 125 cc with a little fabrication.
Yes it is possible but if there is enough space. It will enhance the performance of the bike and it also increase the pick and speed of the machine.

A cc is one cubic centimeter. An engine measurement in cc is the total of the volumes displaced by the cylinders of the engine through one revolution.
1086 cc.
