Greg,
This will be my first calculation on this so feel free to check me. I made this on the assuption that a system is using the big Chalupa with a 18:1 transmission feeding the chain. So backing into a time period of one revolution at 1200 RPM (max power on the curve vs speed), one rev would take .05 seconds. Assuming that the chain slack and all the gear slack could take about 1/4 of a turn to overcome at the output shaft, then the input shaft would have to turn 4.5 turns. So 4.5 x .05 seconds= 225 mSec, very close to the delay you are experiencing. Fudge in your actual speed and you will get even closer I bet. Does this sound feasible?
