200cc engine identification and info

[l-ovie]

Hi all
I have just recently bought a second hand 200cc Yamoto, shaft drive atv and I cannot find any info on it. From what I can gather it seems to be a 200cc loncin (or copy of) OHC??...see attached pic....what do you think?

I want to ensure everything is ok and up to spec, for example valve clearance? I have come across what seem to be conflicting specs (or me with wrong engine identifcation:hmm:), .002" for both or .003" inlet and .004" exhaust.

Does anyone know where I can get service manual or similar??
Your help is much appreciated!!!

Hi, Are you still looking for the manual? I've just rebuild an old 200cc ATV same as your stamp, I think it might refer to Fuxin Manufacturing Limited, they make engines. The Clymer manual for 1980 Honda's 125-200 is the engine you want to take your spec from. I did and my engine is humming. I'm only passing on what I found to be good advice. There's going to be some differences but if you're any way handy you'll figure that out. Valve clearances etc are all there. I have a copy and can email you it if you want.
