Al C. 1,399 #1 Posted June 9, 2016 A couple weeks ago I cleaned the cylinder head on my K341. This is the first time I opened it up. It was pretty dirty. I noticed a notch on the top of the piston head after I cleaned it. Can anyone tell me if this is a problem? Picture attached. Appreciate anyone's viewpoint.
