1976 Honda CB500T · Carburetor Tools Buying guide

Balance two carbs after they are assembled

Confirm you have two carburetors and 5mm vacuum ports. The 1976 CB500T is a two-carb twin, so the kit matches that count when the port thread matches. It is universal, not a Honda-only tool.

Parts to consider

Universal Motorcycle Carburetor Synchronizer Vacuum Gauge ~ 2 Carb Synchronizer Two-carb synchronizerUniversal gauge kit with 5mm threaded extensions. Use it to balance two carburetors. It is not a CB500T-only tool and it is not a parts kit.View part

What you are actually buying

Two gauges, a mountable bracket, 180mm extensions with 5mm threads, 65mm extensions with 5mm threads, hoses, dampening valves, and instructions. That list is the whole kit. If a carburetor needs a new float or a #35 pilot, those are separate parts.

When to use it

Balance the carburetors after they are installed and the slides or throttle cables move together. A sync reading will not fix a torn diaphragm or a wrong jet. Do the mechanical work first, then connect the 5mm fittings.

Synchronizer questions

Is this a carburetor rebuild kit?

No. It is a gauge set for balancing two carburetors. The rebuild kit that names the 1975-76 CB500T is a different product, and each of those kits covers one carburetor.

What thread are the fittings?

5mm. The description says Honda, Kawasaki, and Suzuki bikes with two carbs typically use 5mm connections. Confirm the port on your carburetor.

How many gauges are in the box?

Two, plus the bracket, both lengths of 5mm extension, hoses, and dampening valves.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
