Cylinder head replacement and verification of port processing effect Monkey Custom Part 2 

Monkey Custom Part2
This is a replacement for test run video and cylinder head port handling.
I wondered what would happen to an engine that was just port-processed at 50㏄ and tried it.
As a result, 11000 rpm can be rotated with a margin, but when running with high rotation specifications, it is necessary to replace other parts with parts that support high rotation.
