Review on 🏍️ ALPHA MOTO Motorcycle Vacuum Carburetor Synchronizer Carb Sync Gauge | Honda Suzuki Kawasaki Yamaha CB KZ GS XS 550 650 750 850 900 | Video Demo | Made in Taiwan by Sean Perry

Gauges look nice and have a nice finish and the kit comes with multiple connectors and four hoses to connect to the bike. It seems to have everything you need. However, the kit does not come with instructions and the gauge readings do not reset to the same digit for each gauge. I'll try to fit each sensor to the same throttle body first to make sure they all read the same vacuum reading before using the tool. The dials have markings for all 5 units of measurement, no markings for individual units of measurement. It would be nice to see all the throttle bodies showing the same value without having to guess. Under each gauge are adjustment knobs that seat the needle into the valve seat. This is to prevent the display from jumping, but I have no idea how to install the buttons because there are no instructions. I couldn't find any instructions online either.
