Carb Tuning - Synchro attachment

[jtlandreneau]

1978 CB550K, just rebuilt the engine - wanted to tune the carbs to get her really purring (idle is OK at the moment, couple of dead spots in the upper RPMs)

I bought the vacuum gauge kit with the 5mm brass extensions, but can't find where they attach. It looks like my intake runners (carb manifold?) doesn't have a screw to take out to which I could attach the syncro.... Thoughts? Pictures? Forum link? Been searching the internet tubes for a while now... figured it was time to ask the experts.

Post pictures of your carbs, maybe your just missing the screws

Hopefully the pictures make sense... Don't know where to attach the Synchro gauge, no holes in the Intake manifold
