Both the OHV version and the FlatHead version of the Lifan 79cc seems to fit on a frame on which I'm working on,
but, which one of them has less "downsides"?

I read so much threads regarding OHV and flat head engines which I can't take a choice, I kinda don't trust the flat head,
despite its has proven to be an excellent motor.

With an OHV you can play around with the valve lash without grinding the valves, at the price of an heavier and more complicate
engine, while with a FlatHead, you have a bullet proof and simple engine, perhaps, if you mess around with grinding the valve for setting the lash,
you're screwed.
