I bought this as I tried a standard analogue manometer and found it to be fiddly and inconsistent. The SynchroKing Balancer is easy to set up and operate. I am able to get 4 carburetors within a few mmHg of each other. It comes in a protective carry case that keeps all the parts together. My only minor complaint was having to change over the original vacuum nipples to the ones supplied to have the vacuum lines fit correctly as I would like to keep the bike as original as possible, but this small sacrifice is well worth it. Only thing I had to purchase to complete the changeover was the vacuum connector caps which are a few dollars at the local Autobarn.
Great product fitted the sensor as instructed, hooked up the battery and after warming up worked perfectly. Tuning a turbocharged 2l, 6 cylinder on lpg. 👌
