Zoom Slanthead Engine

What is your opion on the zoom 68.5cc defect on cylinder where
intake bolts up with the small holes way back on the cylinder?
Those that ordered jet black will not even notice it. Thats why
I ordered Jet Silver to inspect. Other than that it is one of the best
casting for looks and straight fins I have ever seen. There back where it is
difficult to spot. Took end of paperclip and it went on through and made hole a
little bit bigger.

It is very difficult to spot the pin hole in the casting because of
the location. What led me to find it was the intake casting of cylinder
is different than the other engines. Same location on both sides of
cylinder intake. Sorry I had to return the camera that I borrowed.
Stay above bolt holes and go all the way back to cylinder where fins attach.
At first I thought it was a black speck , so on jet black engine you will not
notice it.
