Crankcase polished (not mirror finish because of hard work location, but its pretty smooth 
)
The engine is already mounted. Im going to polish the head, and mount the clutch part and magneto,
Some photos soon.

Here we go..
Another little job i did:
That will improve the combustion flow to the exhaust, hope so

That will improve the travel speed of the flame front, help reduce the formation of carbon buildup, and reflect more heat down into the combustion chamber while slightly reducing the temperature of the cylinder head. As for increasing the combustion gasses ability to flow to the exhaust port, no it won't really do that.
The pits left in the casting from the factory will accumulate carbon buildup and lead to hot spots which can cause pre-ignition; especially that large one near the edge, right in the middle of the squish band.

The oil seals i get from a great store here in Portugal. I can send to anyone at the price of their cost, just send me a PM
Yes, that polish in the crankcase will increase the speed the gas flows..
Soon the engine will scream (maybe not scream because of break in period, bu the first start i will make a video
