When I put the plug back in after looking at before I rode today I thought to myself something did not feel right, I was actually wonderering if something was going on with the threads even before this I thought the threads felt a little weirdScrew the plug into the head tight and test how far it extends into the combustion chamber with a spare piston. If the plug leaves a mark, then you need a new head. I don't think the plug is the issue.
Pull the cylinder off and check the piston pins and rings.
