125VX to 200VXR

HEllo,

i was wondering if i change my cylinder from a 125cc to an original 200cc

Do i have to change anything else.

I need to buy a 125cc cylinder kit and +some more money and get the 200cc cylinder.

The question:

Would it fit to my engine?

Would my cranck resist?

Any else changes?

 

Any reply is highly appriciated

 

 

Thanks
