Checking the X-distance
Info
The X-distance is the distance defined for the piston protrusion, when the cylinder is clamped down and the piston is at top
dead center.
The X-distance must be checked very carefully. If the X-distance is too large, the compression decreases and the engine loses
power. If the X-distance is too small, the engine knocks and overheats.
