I need help! I have a CT-525 with about 1 season on it. Never ran over 7500 RPM, never been hot and always had good oil preasure. My problem started when I blew a motor last week, took the bottom end out. Number four pistion was completely gone. And I think that is what started it all. I put a new CT-525 in and 15 laps later number 4 pistion is gone and not much left of the bottom end. Was turning about 7300 RPM and no warning signs, did not start to knock or miss just Kaboom. Anyone have any ideas on what could cause this? MSD box? Need help.
