If you are synchronising the carburetors on your Honda CX500, GL500, CX650 or GL650 motorcycle you will need to know the location of the intake vacuum ports and the carb sync screw. The sync screw is inbetween the carbs on all of the models but it is not necessarily obvious if you aren't sure what to look for. Below are some pics that might help.
So far we only have the one pic - we will add to it over time. In the meantime, the vacuum ports are on the aluminium parts of the intake tubes between the carbs and engine head - this is the same for all models. One port per side.
The sync screw on your Honda CX500 with the single spine frame looks like this:
Inbetween the carbs. We will get a wider shot.
Coming soon. It looks the same as the one pictured above, it's just stuck inbetween carbs that are a lot closer together.
The location of the balance screw:
Near the vacuum port for the vacuum line tha goes to the petcock, on the front side of the carbs (front as in front when installed in the motor).
Now head back to the main carb page for the CX and GL V-twins for the next step.
