what is in the first picture?
I'm amazed at how clean that piston head is.. but confused as to how it can be so clean, and the cc top and valves so dirty at the same time.
Regardless, I wish the piston heads in my Fusion's engine were that clean.

the cam wore and dished the intake follower (1st pic) so the valve timing was off, beyond adjustment, after six months of getting worse after more adjustments it wound up in Wes's garage for repair.

Indeed.
OTOH, I assume you can take some comfort from your Fusion's dirty bits still forming a working engine, unlike the shiny one's pictured.

It looks good. So much for TCW3 carbon fouling an engine.......
Valves look sunken. I put 56k on a kawasaki mojave and they didnt look like that.

Why does it clean the top of the piston, but not the cylinder head?

ATV itself looks good for its age too.
My 2005 Rancher looks a little rough. Has been in the Phoenix sun for a long time.

Just guessing, but the head will be colder than the piston...

The bore looks mirror-smooth judging by how clear the reflection of the lettering on the piston is.
Looks like the cross-hatching on the cylinder is gone so minus a point for "upper cylinder lube" there.

What brand of tcw-3? What engine oil used? How often did you change oil?
By the looks of the head the valve stem seals have been leaking a little.
For reference here is a rebuild of a 2007 Recon with pics.
