1979 Honda CB400TII Hawk II · Carburetor Tools Buying guide

Check adapter reach and readable vacuum gauges

This kit brings the two readings together on a mountable bracket. The important purchase checks are the 5 mm extension threads, access at the motorcycle and a practical route for each hose.

Parts to consider

Universal Motorcycle Carburetor Synchronizer Vacuum Gauge ~ 2 Carb Synchronizer Twin-carb vacuum gauge kitTwo gauges with a mountable bracket, hoses, damping valves and instructions. Includes 180 mm and 65 mm extensions with 5 mm threaded connections.View part

Choose adapters for the connections you have

Inspect the vacuum access points before ordering, particularly if the carburetors have been changed. The included extensions use 5 mm threads, with different lengths to help reach the connections. Confirm both thread suitability and physical access rather than selecting a kit by gauge count alone.

Read the kit and Honda instructions together

The supplied damping valves help control gauge needle movement. Use the kit instructions for that equipment and the correct Honda procedure for synchronization preparation and adjustment. A stable, visible gauge arrangement makes the comparison practical without inventing settings from the markings on the gauge face.

Common buying questions

Why are two extension lengths supplied?

The kit includes 180 mm and 65 mm extensions, both with 5 mm threads. Compare their reach with the access on your motorcycle; the availability of two lengths does not establish that every connection will fit.

Does the kit include a way to steady the gauge needles?

Yes, damping valves are included to help control needle movement. Follow the supplied instructions for their use and support the two gauges where both readings can be observed during the Honda synchronization procedure.

Which instructions should I use for the carburetor adjustment?

Use the Honda service information appropriate to the 1979 motorcycle and its installed carburetors. The kit instructions explain the measuring equipment; they do not replace model-specific preparation, adjustment steps or specifications.
