Time for an update with some new pictures!
Rocker Arms pulled and organized.

Valves look great! Little crud on the #3 but will easily scrape off.

Likewise on the pistons cylinders smooth and free moving

Cylinders in great condition

Everything looks good on this side

Sprocket is covered in old smelly crap- I'll be cleaning this soon

Clutch/Shifter looks good how do I tell if the gears are worn? gotta open the case still?

Engine as it stands today

Anyways so thats the engine currently. Im starting to wonder about cleaning what Ive pulled so far, painting the cooling fins like I want buying the new gaskets I'll need and put it back together. Everything internally is looking MUCH better than I had expected.
Thoughts from the group?
