<DIV>Aluminum fatigue could be part of the problem. After how many flights the piston is developing cracks. If this a general problem?</DIV>

<DIV>I don't think it's a fit problem John, the YS has a teflon insert on both ends of the piston pin that keeps it in place and protects the liner. They push out easily with the pin, so it is basically a free floating piston pin, besides it is fairly evident that the crack is originating from the top of the piston as the center looks like it is pushed down.</DIV>
