We have finished a race with 1 less rod and piston. We just pulled the saw out cut the rod hammered the piston up, and backed off the adjusters. She shook a little more but finished the last 100 miles of the race. It was like sitting on one of the for massager's at the fair for 3 hours. You could not feel anything but your head, arms and hands. It was hard to walk after words. My ass felt like jello for 2 hours. I was scared fart......
