Syncing carbs on CB550

I probably need to sync mine as well.

Additional info:

Mistakes made were syncing with the RPM way too high. It should be at idle or about 1000 RPM for the Cb550. This is where the adjustment is most sensitive.

With these particular carbs, you pick the carb with the highest vacuum, declare it the "master" and never adjust the slide on that one. You adjust the other three to the reading the "master" carb has.
Reason being, is that it is possible to skew all the slides adjusters so that idle speeds can't be achieved by the idle knob (likely what was wrong with the bike in the video).
