Two strokes have an index pin in the piston to keep the ring from spinning. The reason for this is, two strokes have ports and if you allow the ring to spin, it will hook on the port and break the piston and/or the ring. Four strokes have no ports so they have no indexing pin.

Thanks!
I have yet to tear into the YFZ motor, so I am still accustomed to the 2-stroke motors. [img]i/expressions/face-icon-small-wink.gif[/img]
