Kawasaki Prairie 700 Smoking after warm

[Lance Workman]

Kawasaki Prairie 700 is the machine. It’s starts and runs but has a miss. After running it til it’s warm, it’s start smoking like your spraying for mosquitoes. Has oil in the breather also. Checked compressions and getting low 40psi both holes. I know this has a decompression lobe. Any other ideas? Leak down check? I’m guessing it pretty much has to be rings. With it blowing oil back into the breather. Normal typical sign I suppose?

Pretty typical symptoms of worn smooth out or broken rings.  Set of good rings, hone, handful of gaskets and i'd bet it's good as new.

Did hou have luck fixing the smoking?

Shouldnt even run on low 40s compression, so pressure relief valve is kicking in on reading. But i do think your compression is low and it needs rings.
