125 Converted To 200 Anyone Done One?

I have a 125 Pro FM237 forward kick for my next project and am considering sizing up the barrel and piston to a 200 when I go through the engine.

I would love to hear from anyone who has done this first hand on either the Fantic or a Minarelli rear kick engine.

What other than the barrel, piston and carb will need changing?

Will the 125 flywheel be heavy enough?

I haven't ridden a 125 yet and wonder if the 3hp increase is really worth it, especially if the 125 barrel is in good condition.

I had a 1983 Fantic 125 pro twinshock forward kick bike with Densi ignition , it had a 1.492 kg flywheel , i played around with different engine parts over the years , and at one time had a 205 (156cc) mono engine in it , motoplat ignition flywheel weighed 1.601 kg , so extra weight not really needed . Bike gone now , but i think i ended up with a 51- 52 tooth rear (428) sprocket .... Best handling bike i ever had ...
