Here are some shots as the damage to the chain guide rail became more visible and apparent. With every removed item the view became scarier.

There is also a view of the number two and number three pistons and cylinder bores. The cylinder bores look to be in amazingly good condition. There was a lot of flakey black soot in there, which left some crumbly ash after I wiped it out. I will be rolling the engine over a few times to clean out the crevice between the piston and cylinder and trying to polish the stain away at the top of the cylinder bore. There is no wear lip or any other sign of anything bad in the piston to cylinder interface.

Another set of photos coming to show the split dynamic balancer. Jim
