4 1/4" stroke and more I really don't like.. it puts the oil rings WAY to close to the pin, .... JMHO.




Curious, exactly what dimension between the oil ring and pin is too small?

I prefer the 4.25 arm w/ 2.2 big end, 7.1 rod and .990 pin for the following reasons: 1)Bigger, 2)lighter piston, 3)better rod/throw ratio, 4)lighter rotating. And there is no down side.

But, in the end, it likely makes no measurable difference to us street guys.
