1975 Honda CB500T · Carburetor Tools Buying guide

What you can verify on the kit itself

Two gauges, a mountable bracket, hoses, dampening valves, and instructions come with 180mm and 65mm extensions. Both lengths are 5mm thread. No other thread is described, and the CB500T is not named.

Parts to consider

Universal Motorcycle Carburetor Synchronizer Vacuum Gauge ~ 2 Carb Synchronizer Two-carb vacuum synchronizerUse this kit on a bike with two carburetors. It includes two gauges, a mountable bracket, the necessary hoses, dampening valves to control needle jump, and instructions. The 180mm extensions and the 65mm extensions are both specified with 5mm threads, the size those Honda, Kawasaki, and Suzuki models typically use.View part

You are not choosing an extension length

The order is not a short-extension kit versus a long-extension kit. Both the 180mm extensions and the 65mm extensions are included, and both are 5mm thread. Hoses are included too, described only as the necessary hoses, with no hose length printed. If the ports are not 5mm, no second adapter is described.

What the dampening valves are for

The dampening valves calm needle jump while you compare the two carburetors. You also get two gauges, a bracket, hoses, and instructions. No vacuum spec or engine speed is given, so balance the carbs against each other rather than a printed number.

Synchronizer kit questions

Will this kit sync a single carburetor?

It is for two carbs, includes two gauges, and also mentions throttle bodies. It is not a one-carb tool and does not name the CB500T. Count the carburetors first. Honda, Kawasaki, and Suzuki are the brands, typically with 5mm connections.

Is any extension a different thread from 5mm?

No other thread is printed. Both the 180mm and the 65mm extensions are 5mm. Hoses are included, but no alternate adapter is described. If the carburetor fitting is not 5mm, this kit does not offer another size.

Are hoses, dampening valves, and instructions included?

Yes. With the two gauges and bracket you get the hoses, dampening valves, and instructions. The extensions are 180 mm and 65 mm, both with 5 mm threads. There is no third gauge and no third extension length.
