Now that I've read through some of my book on the kinematics and dynamics of machinery I see that analyzing the balance of reciprocating engines is much more involved than what I was doing with my calculations. The book devotes at least two chapters to analyzing reciprocating-engine balance and the only calculations that I did that were valid were the ones where I calculated the accelerations of the connecting rod ends. Those accelerations would probably only be representative of the actual forces on the crankshaft if the crankpins and connecting rods had no mass. Here are 14 of approximately 100 pages on engine balance from the book. Maybe later I can plug some specs into these equations and graph them to see the net forces and torques for the different motors.
