just looks like a different head design...definitely different tho

[danger_ranger83]

look at the valve thingys...its weird

[Fasglas]

Those use to be called rotary valves...old stuff. Rotary valves have been around since Moby Dick was a minnow. I had several old two stroke motorcycles from the 1960s that had rotary valves instead of reed valves.

Good ole barrel exhaust valves (2 stroke). Gives you that BRAAAAAAAAAP!

Though they were only 1/4 to 1/2 turn valves.

But cool find for actually being in the combustion chamber. Wonder what kind of leak out you get?
