Has anyone swapped in an already larger motor? XR 200? XL 175??

The Lifan pushrod 200 fits into a XL 100 frame & so I assume the 125 frame also, but I'm trying to stay with the "General".

Anyone have experience?
The xl185 motor goes straight in with a minor mod to the frame to clear the lump at the back of the kickstart, and taking the bolt holes out to 10mm. I'm currently working on putting a 185 barrel on a 125 six speed bottom end with a 185 crank and a one-off 125k2 cyl head converted to roller bearings on the cam.

There's a lot of info around on the net if you look for it.
