I picked up a non-running 1981 XS400 Special. Long story short, the motor spun freely and the starter would spin the motor, but it refused to start. After digging into it, I found that the exhaust valve adjustment screw and locknut had completely fallen out of the rocker arm for the left cylinder.
Luckily, both were sitting there by the valve so I was able to fish those out, but then also found that the rocker arm threads were stripped. I now have the cylinder head off and the defective rocker arm removed with a new one on the way.
My question is could there be damage to the valve face since the adjustment screw wasn't even present?
