Lifan made a 200cc OHC about 10 years ago. One member on here had one on an old Honda 200x.

The model number on the neck says 200gy. So thats that.
My crazy days are long gone. Although i still run around on my xs650 chopper. No blinks, no horn, no rfront fender. I figure at 250 lbs, i should gear it pretty tight and stay off the road. Wich is fine. Im just looking for single track crawler. I have plenty of street worthy bike to scare the kiddies

There's an engine number down by the shift lever. That will tell what you have.

I have that very motor and the stamp near the gearshift is incorrect. The only way for me to determine actual displacement was to remove the head and measure.

For the unfamiliar, one calculation is bore squared x stroke x 0.0007854 = 193.48cc

It should more accurately be V = πr²h, where r - Bore radius, and h =stroke.
