hp2 32:1 after 11-12 tanks.
bottom of exhaust port - pretty clean, pretty dry
top of exhaust port - some black and it's sticky
plug - not sure what to think there!
muffler - pretty black. I don't recall h1r 800 or ultra being this black. recall being the key word. Kinda sooty IMO.
piston top - no pic - peering through spark plug hole - looks a lot like keith's 261. Nice transfer wash bare metal. Rest is moist black.
piston skirt - drenched with oil. no scratches.
edit - mixing up some more hp2 - going to run it at 36:1 and see what if anything changes.
