Its not easy to see the wash. You may want to use improved lighting on the tops of the pistons and take close up pics of each cylinder.
 
That's all I have for pics, added the picture of the head as well. Motor is no longer apart.
After these pics were taken, found the powervalves to be well out of adjustment. Fixed that, but haven't ridden it since.
One was much looser than the others, but cant remember which
Also, the sled had a bad flat spot in the middle, almost felt like the needles were too low. But that may have been powervalves.
