Part 1 of 4: CFMoto 250cc Head Rebuild 172MM Low Compression GY6

In part 1 of 4: I dismantle the head all the way to piston removal. Part 2 will show the head rebuild process with exerts and specs from the service manual.

Project Difficulty: Medium "Not Rocker Science but requires patients and attention to detail" (Requires some specialty tools)
My goal with this 4-part series is to give you the confidence that you can do this!
