2009 MUV Big Red

My engine smokes during hard acceleration and deceleration. I am looking for any other reason for this issue. So far it’s not looking good. Compression test cold 85-90 psi. If my specifications are correct compression ratio 9:1. Cylinder compressing should be 140+. The Engine runs good and starts good. 7600 mile indicated. Let me know what you think.

I talked with Anderson Honda Madison IN, yesterday. Info: Starter crank speed 350rpm will produce 80 psi compression check. So cyl and pistion should be good and its just head work.
