Well, the results from the dyno were quite unexpected. Seems the carbs are running very lean. Air fuel ratio's 16-18:1. We did one run without the cleaners and it got a little better.
New direction. I am running Zenith's with 32mm chokes. Stock jetting. We are going to go back to the 27mm chokes for the next test. I will also have some main jets drilled from a 115 to a 125 (0.047 to 0.052 inch) just in case we are still lean.
So the flatness of the engine appears to be a lean condition.
