Looks like the the wrist pin bushings are toast on the 89. Just disassembled the pistons for cleaning and inspection.

The radial play is 0.050 mm, that exceeds the factory limit of 0.037.

Edit. I re-measured in metric and got 24 or 23.99. So the pins should be ok.

Here is a pick of the #5 bearing. That is done.
