Review on Prokomon Vacuum Carburetor Synchronizer PT1171 by Todd Stovall

Works with jigs. I had to use zip ties to hold the supplied hoses to the gauges. The hoses were too loose to use directly on my Nighthawk 750 vacuum port, but various sized screws are included in the ports. So I unscrewed it and used the connectors that came with it. One of the pressure gauges was not at zero and there is no setting. So I had to switch to a different sensor for one cylinder. But it works. Wonderful.
