A freind brought an 86 big red to me because it was smoking badly.
It was worse on startup so I assumed valve seals.
Changed seals and found very little play in the guides.
It still smoked.
I pulled the cylinder and the oil rings were very slack in the bore so I assumed once again I had found the problem. Wrong. still smoked.
What next?
Cylinder was honed and found to be very slightly out of round but still has lots of compression. 170lb.
Appears to be no play in the valve guides but have no way to measure them.
Lost.
