Sounds like you've found out what I had suspected, the counter balance shafts are only used to keep from shaking the mirrors off, in a passenger car, and in your application, you seldom run in that range anyway, or are thru it fast enough, it isn't an issue, is my "theory" correct? If you'll recall, the Vega had a "bob weight" attached to the transmission, which eliminated their vibration harmonics. Thanks! Bob!
