[QUOTE="Pushrod Twin, post: 93205, member: 340"] Yes Bill, different frames do have different vibration characteristics & some people recommend a change in balance factor when changing frame types. I accepted Terry's crank as it was, added my pistons & took my chances. I may go through the weighing & adding or drilling performance, if I need to go back in there, as I did when I built the motor the first time. I will make a pair of flywheels for my B motor, they will be replicas of standard Vincent ones but from normalised SAE4340 because I have a pair of rods I matched & a pin & a new mains spindle etc. That set will get the balance calculations when the time comes.
