61mm kit is readily available.

Here are some ideas, the big bore is a good option.

There are cams for the CB125, but that would be a shot in the dark.

You would think that the body parts would be easy to find given the ridiculous number of them that were manufactured.
Taiwanese is the guru for these mod (they had strict law can't swap engine...)

Hi mate
CG150 ZS162FMJ to 200cc big bore kit, seems if you for a standard barrel and piston from the 200cc you loose compression due to lack of stroke?
Is there a kit or piston that compensates for this? Does 125cc head Have enough combustion chamber surface area?
What's the best way to really get more cc and power?
Chinese mechanics told me little to no gain due to lower compression as the stroke is also a little shorter
125 head need mod? For combustion chamber?
Seems to get it right you need a crank too huh
175cc same issue?
