Enhance Motorcycle Performance with Niome Vacuum Carburetor Synchronizer Carb Sync Gauge for a 2 Cylinder Engine Review

The only thing I didn't like was the hoses are very thin and tend to shrink, just had to go to the parts store and buy new hoses and that's it

Exactly what I was looking for to balance the carbs on my 2 cylinder bike. The valves, when properly adjusted, stabilize the needle, just don't close it too much. Make sure the needle wobbles a little.

Hardware is well protected for transport, sensors work as promised, no calibration needed for what I received. Vacuum dampeners are a little cumbersome to set up (to eliminate ripple), but doable for anyone. Fast delivery of course. Bargain.

The tubing was taped to the back of the instruments, the paint was peeling off in some places and the tubing was cracked in others. The small threaded adapter came with a nut that was too wide. Not enough threads to use the included o-ring and still screw it into the carburetor. Spend a little more money and get a good set.

You can't remove the hoses from the bike or the pressure gauge, they just break. You go out of calibration (arrow not at zero) every time you're done with it. I pulled my carbs after trying to use this sensor to sync them and just looked at it on the bench, the carb sync wasn't even close. All in all POS, save money and buy a real pressure gauge.
