You'll have poor performance if it's too big or too small. Needs to be the right jet or within a small range of jets that will prob work alright to run well. Gotta be careful drilling jets because if the hole is no round at all it can make a big difference in how much flow there is.

If you bore the cylinder and keep the same size piston it'll either never start or damage itself or both. Do not do that. You should be able to find big bore kits that would include what you need. Stock GY6 150 cylinder/piston would be larger than the 125.

Under the valve cover, on top of the cylinder head.

I think 58.5mm is the largest that will bolt on without opening up the cases. PFS part number 169-314 is an example.
