Default Engine starting to smoke

Ok my 2010 grubee skyhawk 66/80 is starting to smoke, I noticed it the other day after after coming to a stop.

I know that it smokes when its warming up so thats not it, I think something happen internally cause it wasnt doing this until now.

I have around 170 miles on the engine, mostly I only cruise with it around 18-22 MPH but have taken it to 35 a few times. My breakin was 24:1 then normal mix after breakin is 32:1

when keeping it around 18-20 its smoking some, but when running it at 25 or over it will smoke bad.

Could it be the compression ring or what ever its called thats around the piston gone bad or could it be something else?

God Bless
